The Nationals’ September swoon has largely been tied to poor performances by their starting pitchers, and in particular by abbreviated outings by those starters.

Unable to consistently complete five or more innings, members of the Nats rotation have not only dug their team into early holes, they’ve put added strain on a bullpen that’s not built to withstand this much work.

So the last thing anyone wanted to see tonight in the opener of a weekend series against the Dodgers, the first of 17 consecutive scheduled games heading into the season’s final week, was another short outing by MacKenzie Gore. The left-hander lasted only four innings, and even though he technically kept his team in the game, the work that was then required of the bullpen was too much to overcome in what finished as an 8-5, rain-delayed loss to Los Angeles.

Not even the thunderstorm that popped up with two outs in the top of the seventh could salvage anything for the Nats. The rain didn't last long enough for officials to call the game at that point, so Davey Martinez had to ask Amos Willingham (his sixth reliever of the night) to pitch the final 2 1/3 innings following a 1-hour, 34-minute delay.

In the end, Martinez summoned all but two of his eight bullpen arms. Willingham was the only one who recorded three outs. Two were charged with two runs a piece: Robert Garcia and Jordan Weems, who combined to allow the decisive four runs in the top of the sixth of a game that saw Nationals pitchers issue nine total walks.

It was an eventful off-day for the Nationals, who have made a roster move heading into tonight’s series opener against the Dodgers. Riley Adams unfortunately did break the hamate bone in his left wrist on Wednesday night, so he’s on the 10-day injured list and out for the rest of the season. Taking his place on the roster is Luis García, who was recalled from Triple-A Rochester and will get another shot to prove he has made adjustments since his demotion last month.

García is right back in the lineup, batting eighth and starting at second base. Keibert Ruiz is catching, but I would imagine we’re going to see more of Drew Millas down the stretch now that Adams is out. Lane Thomas also is out for the third straight game, his back still not fully healed. Thomas said the other day he expected to return “Friday or Saturday,” so he still has a chance to make good on that.

MacKenzie Gore, meanwhile, returns after going on bereavement leave and will be making his first start in 10 days. The left-hander looked like he needed a breather after that last outing in Toronto, so we’ll see if the extra rest did him any good. It’s not an easy challenge for him, facing a tough Dodgers lineup tonight.

Lane Thomas is out of the Nationals lineup for the second straight night after receiving an injection in his back, but the outfielder expects to be back playing this weekend.

Thomas was encouraged by results of the MRI he received Tuesday, saying it did not show any injury of significance.

“Just a little inflammation in a few areas,” he said. “Got an injection. You just can’t do anything for 48 hours after that, so I should be good for Friday or maybe Saturday.”

Thomas admitted his back had been a minor issue for a while, but it flared up on him while making a throw one week ago in Toronto. He was held out of the lineup the following night but returned to play the rest of the weekend against the Marlins and wound up homering three straight days.

When the back was still bothering him after all that, Thomas was sent for Tuesday’s MRI and missed the Nationals’ series opener against the Mets.

CJ Abrams has missed only 12 games this season. Lane Thomas has missed only five. Tonight, the Nationals will be without both stalwarts for the first time in 2023.

Davey Martinez’s lineup card for the series opener against the Mets doesn’t look like any previous one he has submitted this season. Rookie Jacob Young is leading off, with Joey Meneses batting second, Keibert Ruiz slotted third and Riley Adams hitting cleanup for the first time in his career.

Such is the byproduct of a lineup missing the team’s usual No. 1 and No. 2 hitter.

Abrams’ day off was scheduled, according to Martinez, who noted how the 22-year-old shortstop has looked worn down in the last week as a tough schedule and the reality of September baseball converged.

“The way he plays the game, he’s constantly using his legs,” Martinez said. “He plays a premium position. He’s constantly running, on his feet, stealing bases. He’s been doing a lot of things, diving everywhere. I just felt like over the last few days – and the fact it’s going to be so hot – having a day off yesterday and a day off today could reset him a little bit.”

MacKenzie Gore will remain on bereavement leave and miss his next scheduled turn through the rotation.

Gore, who would’ve been on turn to start Tuesday against the Mets, went on bereavement leave Thursday. Manager Davey Martinez said today the left-hander won’t be back in time to make that start and instead will be pushed to a later date.

“When he comes back, we’ll figure out where he’s at,” Martinez said. “I want him to go through his routine, and then we’ll figure out where to plop him. If we have to back off a couple guys a little bit, that would actually be a good thing if we can put him in the middle of those guys. We’ll see how he feels when he gets back.”

Though the circumstances that led to this weren’t intended, the Nationals did want to find a way to give Gore some extra time off down the stretch of his first full big league season. The 24-year-old has totaled 132 1/3 innings, most in his professional career by a significant amount. His previous high was 101 innings in 2019 as a minor leaguer with the Padres. He totaled only 87 innings between the majors and minors last season while missing time with an elbow injury.

Gore last pitched Tuesday in Toronto, allowing one run over five innings but needing 106 pitches to do it. With Patrick Corbin and Joan Adon now scheduled to start a two-game series against the Mets that includes off-days on both the front and back ends, Gore will wind up getting at least 10 days of rest before potentially returning to the mound next weekend against the Dodgers.

Johnny DiPuglia, the Nationals’ longtime head of international scouting, has resigned after nearly 15 years with the organization, creating an opening for a prominent position within the front office as its longtime general manager continues to negotiate his own extension.

DiPuglia confirmed his resignation but did not offer details of the move, which was first reported by the Washington Post.

Initially hired in 2009, DiPuglia was tasked with overhauling a Latin American scouting and development operation that was in disarray following a scandal involving the falsifying of supposed top prospect Esmailyn Gonzalez’s name, age and playing ability. That scandal wound up costing both former GM Jim Bowden and special assistant Jose Rijo their jobs, with Mike Rizzo ascending to the GM position and hiring DiPuglia away from the Red Sox, where he served as Latin American scouting director.

Over the ensuing decade-plus, DiPuglia, 60, was rewarded with several promotions, most recently named vice president and assistant GM for international operations in November 2019. One month later, he was honored at baseball’s Winter Meetings with the Professional Scouts International Scout of the Year Award.

Under DiPuglia’s watch, the Nationals both spent considerable money on Latin American prospects and watched several of them become major leaguers, with Juan Soto headlining a group that also includes Victor Robles, Luis García, Joan Adon, Jose A. Ferrer, Wander Suero, Reynaldo López, Wilmer Difo, Jefry Rodriguez and Israel Pineda.

Finally back home, the Nationals are feeling the effects of their 10-game road trip that took them to four different cities in 11 days.

Lane Thomas was scratched from manager Davey Martinez’s original lineup for tonight’s homestand opener against the Marlins after he still felt stiffness in his back. The right fielder was replaced by Alex Call in the seventh inning of yesterday’s loss to the Blue Jays after telling his manager he felt his back tighten up on him during the game, which Martinez said three days playing on artificial turf can do.

“We just scratched him,” Martinez said during his pregame media session. “He's still a little bit tight, so I don't want to take a chance. He's gonna get worked on and hopefully, he's available to pinch-hit.”

Everyone else in the lineup moved up the order, putting Joey Meneses in Thomas’ usual No. 2 spot behind leadoff man CJ Abrams. Against Marlins lefty Braxton Garrett, the Nats have Jake Alu in left field, Jacob Young in center and Alex Call in right.

Martinez wasn’t prepared to definitely announce his lineup during his pregame press conference, but he was prepared to announce Josiah Gray will start Sunday’s finale after the right-hander threw his routine bullpen session today.

After a successful 5-4 road trip, the Nationals have returned home to begin a nine-game homestand, starting with four games this weekend against the Marlins.

A team they have struggled to beat since the start of last season, the Nationals finally won a series against the Fish, taking two of three against their division rivals in Miami last weekend. While the Nats have been winning over the last two months (29-19 in their last 47 games), the Marlins have been falling down the standings by dipping below .500 for the first time since May with a loss to the Rays last night.

Joan Adon will get his second start against the Marlins in less than a week. He impressed Friday by completing six shutout innings with no walks and three hits while earning just his third major league win. The young right-hander will try to reverse his fortunes at home tonight: He has a 10.29 ERA over two starts at Nationals Park compared to a 2.25 ERA in his two road starts.

Braxton Garrett will also get his second chance at the Nationals in less than a week, as he was Adon’s opposition last week in Miami. The left-hander turned in a quality start with three runs over six innings, but that was enough to charge him with the loss. He tossed six innings of one-run ball with eight strikeouts here back in June.

There was a pregame roster move to report: The Nationals placed MacKenzie Gore on the bereavement list and recalled Joe La Sorsa to the active roster. Gore was possibly in line to start Sunday if the Nats decided to give Josiah Gray extra rest after his bullpen session tomorrow. If not Gore nor Gray for Sunday, they could use a bullpen game instead, especially with rosters expanding to 28 players tomorrow.

TORONTO – While they’re certainly doing everything they can to try to keep winning as many games as they can, the Nationals are still using the final month-plus of this ever-encouraging season to evaluate young players who could (or already do) fit into the long-term plan around here.

When both sides of the equation come together like they did tonight in a tense, 5-4 victory over the Blue Jays, it’s a win-win for the organization.

"We're playing the best ball we've been playing all season," said closer Kyle Finnegan, who survived a harrowing bottom of the ninth. "For the young guys to be a part of it, and to see they can contribute to a playoff-type atmosphere, is great for them."

The Nationals not only bounced back from rare back-to-back losses and gave themselves a shot at a sixth consecutive series victory Wednesday afternoon. They did so thanks to the contributions of young players, two of them key pieces to the rebuild, one of them a surprising potential addition to the list after he seemingly had been written off, the other a recent call-up who made his presence known tonight with a big-time moment in the field.

MacKenzie Gore overcame a laborious first few innings to finish strong, allowing just one run over five innings to emerge with the win. Keibert Ruiz’s three-run homer proved the difference. Carter Kieboom’s two-run homer added another chapter to the third baseman’s growing comeback campaign. And Jacob Young’s 300-foot strike from center field to the plate completed a brilliant double play to end an eighth inning that was about to turn south on the Nats.

TORONTO – The Nationals have won five series in a row. They had also won three series openers in a row before dropping Monday night’s game to the Blue Jays. And they haven’t lost three games in a row since early July, when they were swept in a four-game series by the Reds and then lost the following day to the Rangers before embarking on this current 27-17 run.

So this has surprisingly become unfamiliar territory for the Nats, looking to bounce back and recapture control of a series. They’ll attempt to do that tonight, looking to take an early lead on José Berríos and then get a quality start out of MacKenzie Gore.

Gore was not good in his last outing, surrendering a pair of homers (including a grand slam) to Aaron Judge at Yankee Stadium and departing after 80 pitches in four innings. He was hurt by his defense that night, but he didn’t pick up his teammates when he had the chance. And he expects more of himself.

Though they needed to use four relievers to cover six innings Monday, the Nationals bullpen should be in decent shape if Gore can go at least five innings, preferably six. Kyle Finnegan, Hunter Harvey and Mason Thompson are all fresh, with Finnegan having not pitched since Saturday and Harvey having been off since Friday.

NEW YORK – What was already the Nationals’ worst night in weeks, strictly from a performance standpoint, turned worse in the bottom of the seventh at Yankee Stadium.

A 9-1 loss to New York included a disastrous second inning for MacKenzie Gore and a defense behind him that was tough to watch, but that paled in comparison to the sight of Stone Garrett being carted off the field in tears after suffering what appeared to be a serious lower left leg injury.

The Nationals, who had won 20 of their last 30 and were trying to deal the Yankees their first 10-game losing streak in 110 years, were far more distraught about their young outfielder, whose promising season may have come to a devastating conclusion as he tried to make a spectacular catch to rob DJ LeMahieu of a homer that barely cleared the fence in right.

"Just one of those situations ... just sucks to see ... praying for him," Gore, one of Garrett's closest friends on the team, said as he unsuccessfully tried to hold back tears, needing to step away for a minute to compose himself.

His team already trailing by six runs at the time, Garrett raced back to the wall in search of LeMahieu’s deep drive. He planted his left foot in the padded wall to get leverage for his leap, then fell to the ground and writhed in pain as LeMahieu circled the bases and a crowd of 37,266 roared before fully realizing what happened.

NEW YORK – It’s been two years since the Nationals last won eight of 10 games. It’s been way longer since the Yankees last lost nine in a row. And way longer than that since they lost 10 in a row.

Tuesday night’s 2-1 victory secured the Nats’ first 8-2 stretch since June 2021. It also secured the Yankees’ first nine-game losing streak since 1982. One more tonight and the mighty Bronx Bombers would have their first 10-game losing streak since (gulp) 1913. (For what it’s worth, the Nationals haven’t lost 10 in a row since 2008, which isn’t a bad streak in itself, all things considered.)

MacKenzie Gore will try to do what Josiah Gray did Tuesday night and keep the Yankees from scoring runs in bunches. Gore was outstanding his last time out, shutting out the Red Sox on one hit over 6 1/3 innings before a blister opened up on his left middle finger and forced him from the game. The Nats hope that won’t be an issue again tonight but will keep an eye on it, for sure.

Davey Martinez would probably like more than two runs (each via solo homer) tonight, even though that was barely enough offense to win Tuesday. His lineup will be facing Luis Severino, who enters an astonishing 2-8 with a 7.98 ERA and 1.88 WHIP.

Victor Robles wandered through the Nationals clubhouse Wednesday afternoon, a familiar face but in many ways a forgotten one.

It’s been nearly two months since Robles last played, and he has appeared in only five games since early May, a persistent back injury having sidelined him for the better part of the season now. And given the lack of progress he’s made to date, time may be running out for him to make it back in 2023.

“I worry that we’re definitely getting closer to … I mean, he’s still got to go out and rehab,” manager Davey Martinez said. “He’s got to play. He’s missed a lot. But hopefully we can get him playing again before this year’s up. That will be the goal.”

Robles initially hurt himself sliding into second base on May 6 in Arizona and spent the next six weeks on the injured list. His return to the active roster was short-lived, with only five games played in mid-June before it became clear he wasn’t fully healthy yet and needed to go back on the IL.

The 26-year-old has split his time between D.C. and West Palm Beach, Fla., getting treatment and doing what he can to try to get better. But it’s still an extremely limited rehab program.

There have been some notable bumps along the way, some duds every once in a while when he takes the mound. But there have been more than a few really good nights for MacKenzie Gore in his first full season with the Nationals.

And none as good as the one the crowd at Nationals Park witnessed tonight. Even if it did end abruptly and earlier than anyone would’ve preferred. Though the final outcome more than pleased the home team and its fans.

With a devastating combination of precision, power and efficiency, Gore put together his best start as a big leaguer, overwhelming the Red Sox for 6 1/3 scoreless innings before departing with a blister on his left middle finger, an early departure that prefaced a wild finish that saw Boston rally to tie the game but the Nats respond with back-to-back homers by Keibert Ruiz and Stone Garrett for a 6-2 victory.

"That was frustrating," Gore said of the blister forcing him from the game. "But it's something I deal with. There's no panic button or anything. There was a lot of good tonight. We got ahead of guys. Keibert was awesome. We turned a lot of double plays. And we hit some big homers."

Jordan Weems, who replaced Gore on the mound, gave up a game-tying homer to Pablo Reyes in the eighth. No problem, because his teammates were ready to pick him up. Ruiz launched a three-run homer to right-center off reliever Garrett Whitlock, the young catcher’s latest clutch blast in a season full of them.

So for the first time in a while, the Nationals did not mount a late rally Tuesday night. As such, they dropped their series opener to the Red Sox, 5-4, that score holding up from the fourth inning all the way through the ninth. They’ll look to bounce back tonight, whether taking and holding an early lead or rallying again, in the middle game of the interleague series.

After watching Josiah Gray record only nine outs Tuesday, Davey Martinez needed to use five relievers for six innings to finish out the game. So some length from MacKenzie Gore tonight would be very welcome if the left-hander can provide it. Like Gray, Gore has dealt with some high pitch counts and early exits. He’s also surrendered home runs, three of them in his last start against the Phillies.

The Red Sox also send a lefty to the mound in James Paxton, the veteran who hasn’t pitched much since 2019 due to injuries. Paxton has been good since returning healthy this season, though, with a 3.36 ERA in 15 starts. He just tossed 5 1/3 scoreless innings against the Royals last week.

PHILADELPHIA – The Nationals made the decision yesterday to move to a six-man rotation. What was still to be determined was the order in which those six starters would pitch.

They came to that decision today, announcing Joan Adon will start Friday’s series opener at home against the Athletics with Jake Irvin and Trevor Williams following for the rest of the weekend.

That means Josiah Gray will be the first to benefit from the extra rest afforded by the six-man rotation with a week in between starts as he’s lined up to start Tuesday’s series opener against the Red Sox. MacKenzie Gore and Patrick Corbin, tonight’s starter in the Phillies series finale, would then follow suit, each of them also getting a week in between starts.

“We're trying to spread the younger guys out a little bit and give them a couple of extra days off,” manager Davey Martinez said during his pregame media session. “So that's how we decided to do it and that's how it's gonna work out.”

Adon will make his second major league start tomorrow after pitching well in Saturday’s start in Cincinnati when he took a perfect game into the sixth inning and finished with a quality start. It remains to be seen how far the Nationals will push the 24-year-old, who has already surpassed his career high for total innings in a season.

PHILADELPHIA – Yesterday’s news that the Nationals are moving to a six-man rotation wasn’t surprising. It was more a matter of when they would finally decide to do it.

The time works out really well now.

Joan Adon is here and pitched well in his return to a major league mound on Saturday, pitching a perfect game through 6 ⅔ innings. He’s earned another chance to stick with the Nats.

Meanwhile, the young pitchers that have been here all season are entering the Dog Days of August and are either approaching or have already eclipsed their career highs in innings for a season. So, it’s a good time to give Josiah Gray, MacKenzie Gore and Jake Irvin extra rest for the home stretch.

But what other ramifications does a six-man rotation have?

PHILADELPHIA – It has never happened. Not in the team’s 18-year existence since relocating to Washington, D.C., in 2005.

The Nationals have never been no-hit.

In fact, entering today, the franchise had the longest active streak of avoiding a no-hitter dating back 24 years, 0 months and 22 days to David Cone’s perfect game against the Expos at Yankee Stadium on July 18, 1999.

That streak came to an end tonight as Michael Lorenzen, making his first home start for the Phillies since being acquired at the trade deadline from the Tigers, no-hit the Nationals in a 7-0 win in front of 30,406 raucous fans at Citizens Bank Park.

“That was the coolest moment of my baseball career, going out there for the ninth,” Lorenzen told reporters after the game. “Just walking out of the dugout and hearing the fans go wild, it gave me the chills. It gave me that boost of energy that I needed for sure."

PHILADELPHIA – What has long been under consideration – and even to a lesser point expected – came to fruition this afternoon: The Nationals will start using a six-man rotation with Joan Adon getting inserted into the mix.

This has been a topic of conversation for some time now. It was almost more a matter of when not if.

And it makes sense for this young pitching staff. Josiah Gray and Jake Irvin are approaching their career highs in innings for a single season, and MacKenzie Gore has already surpassed his career high. And Irvin and Gore both have recent injury histories.

As for the veterans, Patrick Corbin has proven his durability as a starter throughout the course of a major league season. But Trevor Williams was used mostly as a reliever last year and has already pitched the most innings he has since 2019.

“We actually decided we're gonna go to a six-man rotation,” manager Davey Martinez announced during his pregame media session. “Adon's gonna be plopped in that spot. Just because with Jake Irvin, with Gore, even Josiah, I know he could finish out, he could throw a lot more innings, Trevor Williams who's been a reliever, we want to make sure that we keep their innings intact and understand what we're trying to do — not only for now but the future. So it made a lot of sense to us to bring Adon up here, give him an opportunity to pitch, but also stretch out our pitchers so that we can manage their innings a little bit better.

PHILADELPHIA – Two games down, two to go in this four-game set in the City of Brotherly Love.

After splitting yesterday’s doubleheader, the Nationals have won five of their last six games, six of their eight and seven of their last 10. Don’t look now, but they are only 1 ½ games back of the Mets in the National League East and down to single digits in the Wild Card race at only nine games back of the Reds and Cubs for the final playoff spot.

Don’t want to get anyone’s hopes up, but just for comparison’s sake, they were 13 ½ games behind the fourth-place Marlins and 24 ½ games out of the final Wild Card spot at this time last year.

MacKenzie Gore will get his shot at some of the Phillies’ left-handed power hitters tonight. The southpaw is 6-8 with a 4.34 ERA and 1.420 WHIP in 22 starts. He too will be tasked to keep the Phillies in the ballpark after they hit five home runs between the two games yesterday. Gore has allowed 1.4 home runs per nine innings on the year, but has allowed four longballs over his four starts since the All-Star break.

He’s also looking for a little payback after getting knocked around for seven runs in just 2 ⅔ innings in his start here in early July.
