The Nationals spent the last two nights facing a Braves team desperate for every win it can get as it tries to beat out the Mets for the final wild card berth in the National League. For the next four nights, they’ll face a Marlins team with absolutely nothing to play for. So, the intensity level may be ramped down a bit here over the weekend.

The Nats have absolutely owned Miami this season, winning their first eight head-to-head matchups before finally losing for the first time last week. They’ve got a chance to really put the finishing touches on a dominant performance with at least three more wins this weekend, which would also go a long toward their goal of improving upon last year’s 71-91 record. (They need to go 7-10 the rest of the way to do that.)

Mitchell Parker gets the start, and two of the rookies strongest starts this season have come against the Marlins. The lefty has allowed two runs in 10 innings against them, though he hasn’t faced them since June 16.

The Nationals lineup faces an unknown in Darren McGaughan, a 28-year-old right-hander making only his third career start. A waiver claim from the Guardians earlier this summer, McGaughan owns a 5.14 ERA in 106 career Triple-A starts. He’s not a flamethrower: His fastball averages only 89 mph, and he throws more sweepers than anything else.

Some 3 1/2 months since he last pitched for the Nationals, Trevor Williams took the mound this evening in Harrisburg for a long-awaited rehab start.

The right-hander, out since May 30 with a flexor strain in his elbow, tossed three scoreless innings in the Double-A game against Reading. And barring any setbacks, he’s likely to return to Harrisburg and build up to four or five innings Sunday afternoon, then be activated off the 60-day injured list and rejoin the Nats rotation.

“It’ll be nice to see him back on the mound for us before the season’s over,” manager Davey Martinez said. “So we’re going to try to build him up for that.”

Why are the Nationals so determined to get a 32-year-old pending free agent starts down the stretch of a season that won’t extend into October? It’s not just about giving Williams a chance to pitch a couple more times in the big leagues and perhaps help his cause as he looks for a job in 2025. It’s also about giving the four young starters who are a part of their future the best opportunity to finish the season healthy without being shut down early.

The Nats have been closely monitoring the workloads of MacKenzie Gore, Jake Irvin, Mitchell Parker and DJ Herz. Each has exceeded his previous career high in innings pitched, with three weeks still to go this season.

PITTSBURGH – It’s hard to sweep a doubleheader. It’s even harder when your Game 2 starter can’t get out of the fourth inning, you have to ask four relievers who already pitched in Game 1 to come back and do it again five hours later and you have to ask a lineup loaded with inexperienced hitters to mount a ninth-inning rally against Aroldis Chapman.

How remarkable, then, was the Nationals’ 8-6 win over the Pirates tonight? Under the circumstances, perhaps their most remarkable win of the year.

Having already won this afternoon’s opener, the Nats pulled out all the stops to win the nightcap. Davey Martinez had four of his relievers (Derek Law, Jacob Barnes, Robert Garcia, Kyle Finnegan) pitch both ends of the doubleheader. And after watching Barnes and Garcia combine to give up the two runs that put Pittsburgh on top in the bottom of the eighth, Martinez watched his team rally to score four runs off Chapman in the top of the ninth, with Ildemaro Vargas coming off the bench to deliver the biggest hit of them all.

"They didn't give up," Martinez said. "I talk about these guys every day, about them playing hard to the last out. And they did it again today."

Vargas’ two-out, two-run double to right on a 3-2, 99-mph fastball from Chapman left the PNC Park crowd of 18,937 stunned and the visitors’ dugout bursting with joy. The veteran utility man, who was dressed in full uniform at 11 a.m. but never appeared in a game until 9:40 p.m., smiled wide as he coasted into second base after right fielder Connor Joe came up just short of a diving attempt that would have ended the game.

PITTSBURGH – The Nationals got the job done in Game 1 of today’s doubleheader against the Pirates. DJ Herz tossed five no-hit innings before departing with his pitch count at 87. Dylan Crews homered, doubled and drove in two runs. The bullpen hung on, with Kyle Finnegan barely surviving another harrowing ninth inning to close out a 5-3 victory.

Now it’s onto the nightcap, with the Nats hoping for a rare doubleheader sweep behind another rookie left-hander on the mound. Mitchell Parker makes his 26th big league start, and his 25th was perhaps his strangest yet. He struck out eight and walked only one but gave up four runs over six innings, done in by some terrible defense that included an errant pickoff throw of his own. There’s only so much Parker can control, but if he can simply make the few plays he has to make in the field, he’ll help his cause a lot.

Davey Martinez has a couple of lineup changes from the opener. Jacob Young gets a rare night off, out of the lineup for the first time since July 31. That opens up center field to Dylan Crews for the first time in his brief major league career. Drew Millas will catch Parker, but Keibert Ruiz is still in there, serving as designated hitter against Pirates right-hander Mitch Keller.

If managers preach to their teams they can’t give the opposition more than 27 outs, what do they say about giving them 32 outs?

Truth be told, it probably never comes up, because how often does a team make five defensive gaffes in one nine-inning game? At the major league level, nonetheless.

What, then, will Davey Martinez have to say to his players after today’s 14-1 dismantling by the Cubs, one that was defined not by the hits the Nationals gave up or failed to produce themselves but by the five misplays they made in the field during their least aesthetically pleasing game of the season?

"We're going to pound the same message: We've got to catch the baseball," the manager said in one of the more animated postgame sessions of his seven-year tenure here. "It was awful today. I can't say nothing about it. Our defense was not there. I thought (Mitchell Parker) threw the ball really well. We've got to play defense behind him. You can't drive in runs and let in three or four more runs. You've got to catch the baseball. Defense is a big part of the game. I say that all the time. We've got to catch the ball."

Martinez has had to confront these questions before, but usually as it pertains to one or maybe two plays during the course of a game. Five? This was unprecedented, leaving him to answer how he planned to deliver the aforementioned message to his players.

It’s September, which means there are only four weeks to go in the season and rosters now expand from 26 to 28. For the Nationals, that means the major league debuts of infielder Darren Baker and reliever Zach Brzykcy, who both are being called up from Triple-A Rochester today and joining the active roster. There may not be much playing opportunity for Baker, who plays second base and a little bit of outfield, but Brzykcy (pronounced BRICK-see) should get a good look out of the bullpen the rest of the way.

As for today’s game, the Nats need a win to avoid what would be a very frustrating sweep. Each of the last two games were there for the taking, but they couldn’t avoid one big inning on the mound and then couldn’t deliver one more clutch hit in the ninth inning. They’ll hope to get out to a lead today and then maintain it, perhaps even get the ball to Kyle Finnegan.

Mitchell Parker gets the start, and he had an erratic August. He allowed one or fewer earned runs in six or more innings in three of his starts. But he was torched for nine runs in Philadelphia, and lasted only four innings (despite giving up only two runs) last time out against the Yankees.

The Nationals will be facing left-hander Jordan Wicks, who returns from a long stint on the injured list after having an oblique strain.

To clear space on the 40-man roster for Baker, the Nats transferred Trevor Williams to the 60-day IL. That doesn't change the right-hander's timetime for potentially returning before season's end.

It was undoubtedly the best development of the first half of the Nationals season, a young starting rotation that seemed to break through as one, four potential building blocks all succeeding at the big league level and offering real hope for the near future.

And things turned south for all four of them as the summer progressed. MacKenzie Gore and Jake Irvin no longer looked like All-Stars. Mitchell Parker and DJ Herz looked like rookies with a lot of things that still needed to be ironed out.

So consider the last week-plus a key turning point for that group, which along with veteran Patrick Corbin has turned dominant again.

Over their last nine games, Nationals starters have combined to post a 1.94 ERA and 1.098 WHIP, striking out more than one batter per inning and never once allowing more than two earned runs.

Everyone in the quintet has contributed to the resurgence, but Gore’s part in this play – capped off by Wednesday night’s win over the Yankees – has been the most encouraging.

They came to see Dylan Crews do something big in his major league debut. They left having seen a pedestrian night from the Nationals’ top prospect, three big blasts from the Yankees’ potent lineup and three soul-crushing catches at the wall that spoiled any chance of a victory on one of the most anticipated nights in recent franchise history.

Gleyber Torres, Austin Wells and Jazz Chisholm Jr. each homered, and though Aaron Judge did not, the majors’ leading home run hitter did rob two potential bombs at the wall in center to dazzle a bipartisan crowd of 32,812 and steal the show during a 5-2 New York win on a night that belonged neither to Crews nor Juan Soto.

Crews, the Nats’ first-round pick in last summer’s draft, went 0-for-3 with a walk, a strikeout, a flyout and a groundout in his first career game. It was a rather uneventful night for the 22-year-old, whose biggest moment may have been a fourth-inning throw from right field that just missed nailing Anthony Volpe at the plate.

"First off, playing against the Yankees, and playing against Judge and Soto for the first time, it was a pretty surreal moment going out there," he said. "And obviously playing with my new team I'm playing on now, the Nationals, it's a great feeling. I'm just going to come out tomorrow and do it all over again."

Batting second behind CJ Abrams and in front of James Wood, Crews came up to bat with runners on base only once; he struck out with two on and one out in the sixth, unable to connect with a 3-2 fastball from Nestor Cortes.

It’s a big night on South Capitol Street, and that would’ve already been the case without Dylan Crews crashing the proceedings. Juan Soto, Aaron Judge and the Yankees are in town, and that would be the big storyline under any other circumstances. But now we’ve got the added drama of the latest top prospect to debut for the Nationals.

Crews, who is in right field, joins a Nats lineup that already features James Wood, CJ Abrams and Luis Garcia Jr. They’ll all be facing left-hander Nestor Cortes, who is having a decent but not great season. Cortes enters with a 4.00 ERA and 1.153 WHIP in 26 starts, his biggest issue an inability to keep the ball in the yard. Opponents have hit 21 homers off him, though only two in his last five starts. And in each of his last two starts, he’s tossed seven scoreless innings on three hits with zero walks. So the young Nationals have their work cut out for them. Crews, by the way, will bat second in his debut. (And for those who didn't hear the news Sunday night, Riley Adams was optioned to Triple-A Rochester to clear the roster spot for him.)

So does Mitchell Parker, who faces probably the toughest lineup he’s had to face yet as a big leaguer. The rookie lefty was really good against the Rockies last week (one run, five hits in seven innings) but in his previous start he was torched by the Phillies for nine runs in three-plus innings. Suffice it to say, the Yankees lineup bears more resemblance to the Phillies than the Rockies.

There are a few storm cells set to roll through the area this afternoon, but (fingers crossed) the forecast looks OK for this evening, setting up a big Monday at the ballpark.

Mitchell Parker has endured through three disastrous starts in the last five weeks, once failing to get out of the first inning, once failing to get out of the third inning and most recently getting torched by the Phillies for nine runs.

Those outings could’ve completely spoiled the left-hander’s rookie season, left him spiraling out of control or perhaps even facing a demotion to Triple-A Rochester. Instead, Parker has found a way to shrug them off and right his ship before it goes too wayward.

And with seven sparkling innings tonight to lead the Nationals to an easy 6-1 victory over the Rockies, he enjoyed perhaps his best display of resiliency yet.

"This is who we saw earlier," manager Davey Martinez said. "This is who he can be."

Parker cruised through Colorado’s lineup tonight, needing only 83 pitches to complete seven innings for the fourth time in his 23 big league starts. The 24-year-old remains a work-in-progress, and his 4.26 ERA suggests there’s still plenty of room for improvement (and especially consistency).

The Nationals have scored 14 runs over their last six games. It will not surprise you to learn they’ve gone 1-5 in those games. Scoring runs is good. Not scoring runs is bad. It would really help their chances tonight if they could score some runs.

The Nats will be facing a Rockies starter who has made only six big league appearances before, four of them losses, none of them wins. Right-hander Tanner Gordon is 0-4 with a 7.00 ERA, having allowed 40 batters to reach base in 27 innings, giving up seven homers in the process. A sixth-round pick of the Braves in the 2019 Draft, he throws a low-90s fastball, a slider and a changeup. This is someone the Nationals should believe they can hit tonight.

Mitchell Parker, meanwhile, starts for the home team. The rookie left-hander put together back-to-back quality starts against the Brewers and Angels, then got absolutely roughed up by the Phillies for nine runs in three-plus innings last week. That one start raised his ERA from 3.83 to 4.44. He really needs to get himself back on track tonight.

PHILADELPHIA – Mitchell Parker has been the Nationals’ biggest surprise this season. Entering the year, he was a middle-of-the-pack prospect who was called upon to make his major league debut three weeks into the season.

And here he is in mid-August with the second-best ERA in the Nats rotation. That was, however, until tonight.

Parker entered his 22nd major league start with a 3.83 ERA after allowing just two earned runs (four total) in 17 ⅓ innings over his last three starts. But he had yet to face the dangerous bats in the Phillies lineup during his rookie campaign.

The results in the first matchup weren’t pretty as the young left-hander was knocked around over three-plus innings and the Nats defense played sloppy in an eventual 13-3 rout at the hands of a division rival.

"As we talked about earlier today," manager Davey Martinez said after the loss, "two things that can't happen: We can't give away outs and we can't make pitching mistakes. Today, we did both.”

PHILADELPHIA – After splitting a quick two-game set in Baltimore, the Nationals continue their trip up I-95 to face the Phillies for four games at Citizens Bank Park.

The Nats only have one win in six chances against their division rivals, which came all the way back on April 7 in D.C. They were swept in three games in their more recent meeting here in May. But while the Phils still hold one of the best records in the major leagues, the second half hasn’t been too kind to them as their schedule gets harder to finish the season.

The Phillies entered the All-Star break at 62-34 (.646), but they have gone 8-16 (.333) to start the second half, including losing four of their last five entering tonight. They still have a six-game lead in the National League East, but the Nats can make things more difficult for them with a strong showing this weekend.

Mitchell Parker will try to put that in motion when he takes the mound for his 22nd start. The left-hander has started to regain his groove in the second half, allowing just two earned runs (four total) in 17 ⅓ innings over his last three starts. The 24-year-old has never faced the Phillies, so it will be interesting to see how he handles some of the big bats in their lineup.

On the other hand, the Nats have seen plenty of Zack Wheeler. The right-hander is in the middle of an All-Star season with an 11-5 record, 2.78 ERA and 1.002 WHIP. He gave up two runs in 7 ⅓ innings in a win over the Nats on May 17.

The Nationals already have enough trouble scoring runs and hitting for power when at full strength. Remove their All-Star leadoff hitter from the equation, and the task can feel impossible.

So, when word came down about an hour before first pitch tonight that CJ Abrams had been scratched because of back spasms, even the most optimistic Nats fan had to be concerned this could turn into a long night at the plate.

It was. Until the home team made it worth the wait with a late rally and a rare extra-inning win.

Alex Call’s line drive single just past drawn-in second baseman Luis Guillorme brought Jacob Young home from third and gave the Nationals a rousing, 3-2 victory in 10 innings to avenge Thursday’s 10-inning loss to the Giants.

"The boys wanted it," manager Davey Martinez said. "They wanted it tonight. You could tell. They didn't want another extra innings and not win. They wanted to celebrate."

Twenty-eight major league teams have come to D.C. to face the Nationals at some point during the last two seasons. The only one that hasn’t: the Angels, who remarkably haven’t played here since 2017. That streak finally ends tonight with the opener of a three-game series (weather permitting), and that means the long-awaited return of one of the most important players from the 2019 World Series roster.

Things haven’t gone so great for Anthony Rendon since he left Washington for Anaheim about a month after hoisting the Commissioner’s Trophy. He hasn’t come anywhere close to playing at the same level for the Angels, and he’s dealt with a smorgasbord of injuries on top of that. But he’s healthy now and will finally get the chance to get the ovation he deserves from the Nationals Park crowd.

The Nats, meanwhile, really need a quality start out of Mitchell Parker tonight after four consecutive subpar outings from the rest of the rotation against the Giants. The bullpen is pretty gassed at this point, so a minimum of five innings – preferably six – from Parker would be much appreciated from Davey Martinez.

The Nationals lineup faces an unfamiliar foe in José Soriano. The 25-year-old right-hander was exclusively a reliever last season and didn’t appear in the series in Anaheim. He’s done well as a full-time starter this season, entering with a 3.47 ERA and 1.206 WHIP despite a relatively low strikeout rate (7.4 per nine innings).

UPDATE: CJ Abrams has been scratched from tonight's lineup for reasons not yet disclosed. Nasim Nuñez will get a rare start at shortstop in his place. 

The situation practically begged for James Wood to do something big. Though the Nationals were leading at the time, the prospect of pulling off a 1-0 victory given the current state of their bullpen felt risky at best.

So here was a golden opportunity to extend that lead: Bases loaded, one out in the bottom of the sixth, Wood at the plate as the crowd tried to will the rookie outfielder to a clutch hit.

And when Wood’s sinking liner to left got past a diving Jackson Chourio and rolled all the way to the wall, that crowd roared as four Nationals sprinted around the bases, three of them scoring in front of Wood, who stopped at third with the clutch triple that proved the difference in a tight, 4-3 victory and a series win over the Brewers.

"That was a big moment, and he came through," manager Davey Martinez said of his 21-year-old phenom. "The kid's going to be OK."

It was the latest in a string of clutch hits by Wood, the 21-year-old phenom whose first month in the big leagues has featured plenty of ups and downs and still leaves much to be desired. But what Wood has lacked in consistency, he has made up for in frequently rising to the occasion in big spots.

The Nationals haven’t won a bunch recently. But when they have won, they’ve won in bunches. In fact, every time they’ve snapped a losing streak since July 12, they’ve followed that first win with another win. And if they can keep that pattern up today, they’ll wind up with a series victory over the Brewers, their second series win over the National League Central leaders in a month. At this point, you’ll take that, right?

Mitchell Parker faced Milwaukee in that previous series at American Family Field, and though the Nats wound up winning the game, his start was a disaster. That’s the day Parker failed to get out of the first inning. And he followed up that start with another short one against the Padres. Fortunately, he bounced back in Arizona with five innings of two-run ball, so he should enter this one feeling better about himself.

The Nationals jumped all over Aaron Civale in the first inning Saturday. They’ll try to do the same today against a brand-new face: Tobias Myers. The 25-year-old rookie has been pretty good for the Brewers, with a 3.10 ERA and 1.143 WHIP in 16 games (15 starts). And he’s allowed two or fewer earned runs in seven of his last nine outings, so the right-hander presents a real challenge today.

PHOENIX – The news was only minutes old, and Davey Martinez was still trying to process it and express his thanks to Lane Thomas while also trying to figure out what to do with his lineup for a game that was set to begin in less than three hours.

"It's tough, but I've still got 25 guys out there to get ready to play Arizona," the Nationals manager said shortly after 4 p.m. "They've been playing really well. We've got to be upbeat. It's part of the game. I can only control what I can control, and that's to get these guys ready to play."

The Nats were ready to play tonight, no doubt. They stormed out of the gates to score five runs in the top of the first, then opened up a six-run lead in the top of the sixth and carried a four-run lead into the bottom of the ninth. At which point disaster struck.

Kyle Finnegan, the subject of plenty of trade rumors himself, blew that four-run lead in the ninth and took a shocking 9-8 loss. The All-Star closer retired only one of the six batters he faced, giving up homers to Ketel Marte and ultimately a walk-off homer to Corbin Carroll that left Chase Field shaking and the visitors slumping their way back to the dugout.

"In this game, no lead is ever safe, no team is ever out of it," Finnegan said. "You've got three outs to get to win the game, and they're not going to concede the game. They're not going to give away at-bats. They're trying to win the game. And I think they just took really quality at-bats, and I wasn't able to make good enough pitches to get them out."

PHOENIX – It’s a dry 109 degrees here in the Valley of the Sun. Guess it’s only appropriate as the trade market heats up. There have been a number of deals made throughout the baseball world today, though nothing involving the Nationals yet. The day is still young, especially out here in the Pacific Time Zone. (Technically, it’s Mountain Standard Time, because Arizona doesn’t do daylight saving, but that’s not important right now.)

The Nationals come to the desert after taking two of three from the Cardinals, missing out on a sweep Sunday afternoon when Dylan Floro gave up a walk-off homer to Paul Goldschmidt in the bottom of the ninth. They’ll look to get this series off on a positive note against the defending National League champs, who have won 10 of their last 14 to get back into the thick of the Wild Card race.

It’s a matchup of left-handers, with Mitchell Parker against Jordan Montgomery. Parker is coming off back-to-back rough and short starts, having totaled 3 2/3 innings against the Brewers and Padres. The Nats simply need much more from him tonight, especially if they make any moves that deplete their bullpen. Montgomery, one of the top free agents last winter who held out forever before finally signing with Arizona, has been really good in three of his last four starts but was roughed up by the Royals for eight runs in 2 2/3 innings in the other.

Update: Lane Thomas is being traded to the Guardians, per a source familiar with the situation. The Nats are getting 19-year-old left-hander Alex Clemmey (Cleveland's No. 8 prospect per MLB Pipeline), 19-year-old shortstop Rafael Ramirez Jr. (No. 22) and 23-year-old infielder Jose Tena (No. 28 per Baseball America).

More to come soon.

As much as young starting pitching carried the Nationals through the first half of the season, everyone involved has known all along there were no guarantees that group of unproven arms would continue to perform at such a high level through the second half of the season.

This is especially true for the least-experienced members of the group: Mitchell Parker and DJ Herz, neither of whom opened the year in the big leagues but quickly burst onto the scene to make names for themselves.

Upon seeing Herz begin to struggle earlier this month, the Nats decided to demote him to Triple-A and give him an extended All-Star break to rest his arm and mind. He returned Tuesday night and impressed over five innings against the Padres.

The club might be tempted to do something similar with Parker after he got ransacked tonight by San Diego during an ugly, 12-3 loss that ended with utilityman Ildemaro Vargas firing up a crowd of 23,323 with a scoreless top of the ninth featuring a plethora of eephus pitches.

The Nationals are now 0-5 against the Padres this season, 47-50 against everyone else.
