OAKLAND, Calif. – On a day when several struggling hitters finally came through in some big spots, and on a day when their No. 5 starter turned in his third consecutive strong outing, and on a day when they opened up what felt like a comfortable lead in the rubber game of a weekend series, the Nationals somehow still found themselves lamenting a loss at the end of the day.

How did they fall to the Athletics, 7-6, and drop this series? With a bottom-of-the-sixth bullpen meltdown the likes of which they won’t soon want to remember.

When the critical inning began, the Nats held a 6-1 lead, with Trevor Williams cruising toward what should have been his third straight win to begin the season. When the inning ended, that lead evaporated, with Williams pulled three batters in and relievers Derek Law and Jordan Weems allowing six runs to score, all with two outs.

Manager Davey Martinez could have left Williams in longer but knew the veteran’s history of late-inning troubles. But after using his top four relievers (Kyle Finnegan, Hunter Harvey, Robert Garcia and Weems) each of the previous two days, Martinez’s options weren’t as appealing as they might otherwise have been.

Put that all together and you get a particularly frustrating loss for a team that was seeking its second straight series win to cap off a successful week in the Bay Area.

OAKLAND, Calif. – The Nationals have a chance to win their second straight series this afternoon and depart the Bay Area with a 4-2 record in advance of what should be a tough series at Dodger Stadium beginning Monday night. A win today over the Athletics would be good for morale heading to L.A.

The Nats have gotten great starting pitching so far this weekend, with Jake Irvin and MacKenzie Gore combining to allow one run on five hits in 11 innings. But the bullpen also has been taxed, with the top four guys (Kyle Finnegan, Hunter Harvey, Jordan Weems, Robert Garcia) each appearing in both games. You would have to think Davey Martinez wants to avoid using any of them a third straight day unless absolutely necessary. Some length from starter Trevor Williams would help a lot.

At the plate, the Nationals will try to be more productive against Alex Wood than they were against Paul Blackburn or Joe Boyle. Wood has been around for more than a decade now, and he’s faced the Nats a whopping 16 times in his career. Most of those starts, though, came years ago when he was with the Braves, and he was facing a very different lineup than he’ll see today.

OAKLAND, Calif. – Riley Adams has been an everyday catcher before. Just not very often in the big leagues.

Since joining the Nationals in August 2021, Adams has been the team’s No. 2 catcher, backing up Keibert Ruiz, making one or two starts a week except for rare times when Ruiz has been unavailable.

This week has turned into one of those rare times. Ruiz hasn’t played since Monday, beset with flu-like symptoms that have prevented him from playing in any of the Nats’ last four games and likely will sideline him again for today’s series finale against the Athletics.

Aside from one start Wednesday by Drew Millas during his brief promotion from Triple-A Rochester, it’s been all Adams behind the plate this week. And he’s handled the situation with aplomb, delivering both offensively and defensively for a team that has desperately needed it.

“He’s a godsend for me,” manager Davey Martinez said following Sunday’s 3-1 win. “Anytime I call upon him, he does the best he can. Today was another example.”

OAKLAND, Calif. – It’s days like this, performances like this, that make you realize why the Nationals were so high on MacKenzie Gore all along.

The Nats have had promising young left-handers over the years. They’ve had guys with good fastballs. They’ve had pitchers determined to be the best.

But they’ve never had all of that wrapped into one package. Gore has everything going for him; he just needs to start putting it together on a regular basis. And on this day, he did.

With an unhittable fastball that overwhelmed the Athletics lineup, Gore struck out 11 in five scoreless innings, leading the Nationals to a 3-1 victory in one of the signature starts of his burgeoning career.

“It’s beautiful,” manager Davey Martinez said. “He goes out there and attacks the strike zone. He goes out there and competes. Hopefully, we can now see that consistency.”

OAKLAND, Calif. – Things you don’t expect to see when you come to California: a tarp covering the infield. Yes, it’s raining here today, and it’s supposed to rain on and off all day. We can only hope it doesn’t prevent the Nationals and Athletics from playing as scheduled, or at least with minimal delay. Because the idea of a Sunday doubleheader, with a flight to Los Angeles at the end of that, can’t be appealing to anyone.

The Nats got a really good start Friday night out of Jake Irvin, who gave up one hit (alas, a homer) in six innings. They’ll hope for more good stuff today from MacKenzie Gore, who was very strong last time out against the Phillies and now faces what on paper looks like a far less imposing lineup. (I know, I know. Careful what you wish for.)

The Nationals also could use a much better offensive showing than they put forth Friday night, when they managed only one run (Jesse Winker’s ninth-inning homer) and went 0-for-10 with runners in scoring position. The good news: They don’t have to face Paul Blackburn again. It’s right-hander Joe Boyle, a rookie making his sixth career start. He was beat around by the Red Sox but then shut out the Tigers over five innings last time out.

OAKLAND, Calif. – As the Nationals looked up at the massive scoreboards at Oakland Coliseum, they saw the number one listed in the Athletics’ hit column most of the night. It would be changed to a two late in the evening, but that’s not exactly a big number, either.

And yet here the Nats were, coming up to bat in the top of the ninth, trailing the game because one of Oakland’s hits off Jake Irvin was Lawrence Butler’s third-inning homer and none of their own hits had produced a run.

Jesse Winker, at long last, took care of that annoying situation.

Winker’s leadoff homer in the top of the ninth off A’s closer Dany Jiménez finally got the Nats on the board and Irvin off the hook. But when they couldn't take the lead, the game moved into extra innings, at which point Trey Lipscomb made a baserunning blunder and Kyle Finnegan surrendered a walk-off single to Lawrence Butler for a tough 2-1 loss.

"We created some opportunities; just couldn't get that run in," said manager Davey Martinez, whose team went 0-for-10 with runners in scoring position. "Winker was our offense today."

OAKLAND, Calif. – The revolving door that is the 26th man on the Nationals roster stopped on a new name today: Amos Willingham. The club wanted to carry an extra reliever for this weekend’s series against the Athletics, so Willingham got the call to replace catcher Drew Millas, who flew to San Francisco for one game Wednesday before getting sent right back to Triple-A Rochester.

Turns out the Nats might have preferred to keep Millas around a little longer, because Keibert Ruiz remains sick with flu-like symptoms, leaving the team with only one healthy catcher tonight in Riley Adams.

Ruiz hasn’t played since Monday’s series opener against the Giants. Adams caught the following night, then Millas was called up for Wednesday’s game, which he started before being optioned back to Rochester at the end of the day.

Millas’ spot went to Willingham, recalled from Rochester this morning to give the team an eighth reliever.

“We thought we needed another guy in the bullpen,” manager Davey Martinez said. “So he’s going to be with us until otherwise noted. But I really felt like we could use another guy in the bullpen to help us out a little bit. They’ve been out there quite a bit already, so having another guy in the bullpen helps.”

OAKLAND, Calif. – For only the third time in club history, the Nationals are playing at the Oakland Coliseum. They were here in 2014. They were here again in 2017. And now they’re back in 2024. And sadly, this appears to be the last time they’ll be coming here, with the Athletics announcing plans to relocate to Sacramento for three seasons while they wait for their proposed new ballpark to open in Las Vegas. It all makes for a sad situation here for a once-proud franchise and its loyal fan base.

The Nats will look to keep things going in a positive direction tonight after taking two of three across the bay in San Francisco. They’ve got Jake Irvin on the mound for his third start of the season, seeking his first truly good start. (He actually pitched pretty well against the Phillies last week but was done in by one bad pitch to J.T. Realmuto, which turned into a three-run homer.)

Keibert Ruiz once again sits, so he must still be feeling sick. That’s not ideal, because the Nationals sent Drew Millas back to Triple-A Rochester after Wednesday’s game and called up reliever Amos Willingham this morning. So it’s Riley Adams behind the plate, with no real help unless Ruiz feels well enough to play in an emergency.

Major League Baseball, for all its warts, can stake claim to something no other major North American professional sports league can claim: Very few franchise relocations in recent times.

For five decades, in fact, there was only one MLB relocation: the Expos’ move to Washington prior to the 2005 season to become the Nationals. In spite of all of the sport’s other issues, this was a particular point of pride for baseball when comparing itself to the NFL, NBA and NHL.

And then came this week’s news of MLB owners unanimously approving the Athletics’ plan to relocate from Oakland to Las Vegas, and all of a sudden an issue that has barely been on baseball’s mind for a half-century is now the predominant story in the sport.

Baseball, of course, experienced plenty of franchise relocations prior to this long run of stability. The 1950s saw the Dodgers and Giants head west, the Braves move from Boston to Milwaukee, the St. Louis Browns become the Baltimore Orioles and the A’s transfer from Philadelphia to Kansas City. The 1960s then saw the original Senators become the Minnesota Twins, while the Braves (Milwaukee to Atlanta) and A’s (Kansas City to Oakland) relocated again. And the early 1970s saw the Seattle Pilots become the Milwaukee Brewers after only one season and the expansion Senators bolt for Texas to be rebranded as the Rangers.

But that’s ancient history at this point. Modern baseball has been defined by the stability of its franchises, and the addition of expansion teams to grow the league to an even 30 organizations. So the Oakland-to-Vegas announcement feels like a really big deal because in this sport it is a really big deal.

When Jeter Downs stepped to the plate to lead off the bottom of the ninth this afternoon, he had no realistic reason to believe he was about to jumpstart a game-winning rally.

The Nationals trailed the Athletics by five runs, having slogged their way through a mostly lifeless series finale that saw Trevor Williams get roughed up again while their lineup failed to deliver with runners in scoring position again. They would just have to accept a Sunday loss to Oakland but a weekend series victory.

But in the dugout, Dominic Smith was trying to keep his teammates engaged, no matter the score. “We’ve got three outs,” the first baseman told them. “Don’t give any at-bats away. They all matter.”

So by the time Downs somehow found himself stepping back to the plate some 25 minutes later, now with a chance to drive in the winning run, the young infielder had every reason in the world to believe he and his team were actually going to pull this thing off.

And when he delivered the final hit to cap a stunning, six-run rally, Downs could only soak in the moment as teammates mobbed him in the middle of the diamond following the most inexplicable, 8-7 victory most of them had ever experienced.

Though the depleted group has performed remarkably well in his absence, the Nationals bullpen is about to get one of its key members back.

Hunter Harvey, out the last four weeks with an elbow strain, is on track to come off the injured list early this week, according to manager Davey Martinez.

Harvey faced live hitters before Friday’s game at Nationals Park, then threw off the bullpen mound prior to today’s series finale against the Athletics. Barring any complications, the right-hander should be ready to come off the 15-day IL, foregoing a minor league rehab assignment.

“I think Hunter should be ready here in the next couple days,” Martinez said.

Ready for what?

Hello from Nationals Park. Yes, I’m back to work. In person. Many thanks to Bobby Blanco for jumping in to cover in my absence during what proved to be a very eventful week. And many thanks to all of you who offered well wishes while I was recovering from COVID.

The Nationals, as you know, are playing their best baseball of the year. Really, their best baseball in more than two years. They’ve gone 14-8 over the last 3 1/2 weeks, and today they have a chance at their third series sweep in that time, having already disposed of the Giants and Reds.

To do the same to the Athletics, they’ll need a bounce-back start from Trevor Williams, who was roughed up in Philadelphia on Tuesday to the tune of six runs and eight hits in only 4 2/3 innings. The home run has become Williams’ biggest problem; he enters today’s start having surrendered 25 of them this season, second-most in the National League.

The Nats lineup came through with two big hits during Saturday night’s win – Lane Thomas’ game-tying RBI single in the eighth, Keibert Ruiz’s walk-off homer in the ninth – but overall that group went 2-for-15 with runners in scoring position. That’s not usually a recipe for success. They’ll hope to convert in the clutch more this afternoon against A’s left-hander Ken Waldichuk, who enters with a 6.30 ERA and a whopping 5.2 walks issued per nine innings.

The Nationals have been playing well at home over the last month, a stark difference from the first half of the season. It took until the ninth inning, but that trend continued tonight against the Athletics.

With the game tied 2-2 in the bottom of the ninth, Keibert Ruiz stepped to the plate and delivered a first-pitch walk-off home run to right field for a 3-2 win in front of 28,635 screaming fans.

“I was looking for a good pitch to hit," Ruiz said after the victory celebrations. "I got it and I put a good swing on it. Just grateful to god for this opportunity. I've been dreaming for this moment for a long time.”

He got a perfect pitch to hit from Oakland reliever Lucas Erceg. The right-hander left a 97-mph fastball right down the middle of the plate for Ruiz to crush 391 feet into the Nationals bullpen and then trot the bases to his awaiting teammates for a cold Gatorade bath at home plate.

“I can't describe that moment," Ruiz said. "Like I said, I've been dreaming for that moment for a long time and really grateful to god.”

The Nationals have won seven of their last 11 games after last night’s 8-2 win over the Athletics while continuing to play well at home. They have won 10 of their last 12 games on South Capitol Street and have a chance today to clinch their fifth straight home series.

Jake Irvin will look to provide some length after Joan Adon only lasted three innings Friday night due to leg cramps. The right-handed rookie is 3-5 with a 4.93 ERA and 1.440 WHIP over his first 17 major league starts. He has pitched into the sixth in three of his last four outings but only made it to the fifth last weekend in Cincinnati.

The A’s will send out their own right-handed rookie Luis Medina for tonight’s game. The 24-year-old is 3-8 with a 5.47 ERA and 1.532 WHIP over 16 big league appearances, 12 starts. He, too, has been able to provide solid length in his recent starts, but only made it to the fourth in his last outing against the Giants.

Update: Lane Thomas has been scratched from tonight's lineup. He was hit by a pitch in the right wrist last night. Stone Garrett is now in right and batting sixth.

Tonight was supposed to be the first turn of the Nationals’ new six-man rotation, with Joan Adon making his second start since being inserted last week.

But the thing about a six-man rotation is that they need six men to pitch in it.

Adon’s availability moving forward is now in question after he was pulled from tonight’s 8-2 win over the Athletics with cramps in his legs while warming up for the fourth inning.

“I just started on my warmups and I felt it right away in my calf and in my groin a little bit," Adon said after the game, via interpreter Octavio Martinez. "One was my calf on one side and my groin on the other.”

The 26-year-old right-hander, who threw an impressive quality start Saturday in Cincinnati, threw a couple of warmup pitches to backup catcher Riley Adams in between the third and fourth innings. But before Keibert Ruiz could even get his catching gear on, manager Davey Martinez and head athletic trainer Paul Lessard were out of the dugout checking on the starting pitcher and then departed with him.

The Nationals are back home after a successful 4-3 road trip to Cincinnati and Philadelphia. Now they welcome the Athletics, who own the worst record in the majors at 33-82.

The Nats themselves are at 50-66, only five games back of their final 2022 record. They’ll have a chance to surpass that mark on this nine-game homestand.

Joan Adon, recently added as the sixth man in this rotation, will make his second start since rejoining the Nats last week. If you didn’t hear by now, he took a perfect game into the sixth inning before giving up a two-out single Saturday against the Reds. He finished with a quality start and seven strikeouts, earning him more opportunities to pitch at the major league level.

Veteran right-hander Paul Blackburn starts for the A’s in the opener. The 29-year-old is 2-5 with a 4.35 ERA and 1.500 WHIP in 12 games (11 starts) this year. He has been strong over his last three starts, pitching to a 1.56 ERA over 17 ⅓ innings including six shutout innings in his last outing against the Giants.

Blackburn has never faced the Nationals, nor has he faced any current Nats hitters. Same goes for Adon against the A’s.

The Orioles had a surplus of quality minor league infield prospects and they were still seeking a pitcher to slot into their 2023 big league rotation, especially a lefty. Today those two added up to a deal where the Orioles acquired lefty starter Cole Irvin and Single-A right-hander Kyle Virbitsky from the Athletics in exchange for minor league shortstop Darell Hernaiz.

In the deal, the O’s gave up a top 30 prospect – Hernaiz was No. 16 via MLBPipeline.com – but they also acquired a pitcher that has averaged 180 innings the last two years with an ERA of 4.11. He has made 62 starts the last two seasons, but still has four years of team control remaining and will not even be arbitration eligible until after the coming 2023 season.

Here are a few more notes on the new O’s lefty after the deal was officially announced by the Orioles this afternoon:

* Irvin went 9-13 with a 3.93 ERA last year over 181 innings. He recorded strong numbers in WHIP (1.160) and walk rate (1.8) while making 15 quality starts. He produced 1.4 fWAR to rank second among A’s pitchers.

* An A’s beat writer tweeted today that Irvin was likely going to be Oakland’s opening day starting pitcher this year.

The Orioles succeeded today in finding a starting pitcher for their unsettled rotation, consummating a trade after failing to reach terms with a free agent.

Left-hander Cole Irvin and minor league pitcher Kyle Virbitsky were acquired from the Athletics for Single-A infielder Darell Hernaiz. Lefty reliever Darwinzon Hernandez was designated for assignment to make room for Irvin on the 40-man roster.

Irvin, who turns 29 on Tuesday, could be the only left-hander in the Orioles rotation on opening day with John Means recovering from Tommy John surgery and DL Hall a consideration for the bullpen. He’s made 62 starts over the past two seasons and posted a cumulative 4.11 ERA in 359 1/3 innings, with 1.8 walks and 6.4 strikeouts per nine frames in 2022.

The Orioles get more than durability with Irvin, who registered a career-low 3.98 ERA and 1.160 WHIP last year in 30 starts. He’s under team control through 2026.

The Phillies were the third team to draft Irvin, landing him in the fifth round in 2016 out of the University of Oregon. The Athletics acquired him in a cash deal on Jan. 30, 2021.

In years past, today’s result between the 44-86 Nationals and 49-82 Athletics would have been actually important. The finale of a three-game set between teams who have two of the worst records in the major leagues and split the first two matchups would have had draft-order implications for the following year.

But alas, the implementation of the MLB Draft lottery gives the three teams with the worst records an equal chance at next year’s No. 1 overall pick, rendering this just another getaway-day game between two bottom-feeders.

Whatever the stakes, the end result was an exciting 7-5 walk-off victory for the Nationals in 10 innings.

Who else but Joey "Four Bags" Meneses to deliver the game-winning blow?

With two runners on base in a 5-4 game in the 10th, the Nats' new slugging right fielder and No. 2 hitter stepped to the plate to hit a three-run homer for an extra-inning win.

With a victory this afternoon, the Nationals would win the first series against the Athletics played in D.C. since 2005 and the first ever at Nats Park. And they would win this matchup between two teams with two of the worst records in baseball. A matchup that is now meaningless with next year’s MLB Draft lottery. 

After Aníbal Sánchez earned his first win of the season last night, Paolo Espino will look to do the same today. Entering his first career start against the Athletics, Espino is 0-6 with a 4.35 ERA in 34 appearances (14 starts) this year. He made two relief appearances against the A’s in 2017 as a member of the Rangers. 

Espino will be pitching on normal rest after making his last start on Saturday, thanks to Monday’s off-day. Cade Cavalli was supposed to make his second major league start this afternoon, but landed on the 15-day injured list with right shoulder inflammation. Cory Abbott was recalled yesterday to take the top prospect’s spot on the roster and will be available out of the bullpen.

The Athletics will get to see one of their own top prospects make his major league debut in Ken Waldichuk. The 24-year-old lefty is Oakland’s No. 3 prospect, per MLB Pipeline, and was the centerpiece of a four-player package the A’s received from the Yankees in exchange for Frankie Montas and Lou Trivino before the deadline. Waldichuk posted a 2.84 ERA, 1.158 WHIP and 137 strikeouts in 95 innings over his 21 starts between Double-A and Triple-A in the Yankees and A’s systems.

Major league rosters expand to 28 players today. Catcher Tres Barrera and right-hander Mason Thompson have been recalled from Triple-A Rochester.
