When it came time to select a pitcher to promote as their September call-up, the Nationals knew they needed Andrew Alvarez, who will make his major league debut this afternoon as MacKenzie Gore’s replacement in the rotation.

When it came time to select a position player to fill the other slot on their expanded September roster, the Nats chose to go with someone who has been here several times before, in the hopes he can provide a much-needed spark to a team mired in an eight-game losing streak: Nasim Nuñez.

Nuñez was officially recalled from Triple-A Rochester this morning, the 25-year-old making his second big league stint of the season after spending all of the 2024 season here as a Rule 5 Draft pick.

The high-energy infielder may have a tough time cracking the lineup on a regular basis, but interim manager Miguel Cairo did say he’s “going to play some,” with shortstop CJ Abrams and second baseman Luis García Jr. getting occasional days off down the stretch.

“He’s exciting,” Cairo said. “A lot of energy. He was doing good at Triple-A. He was doing everything. He was hitting line drives, he was bunting. That’s the kind of player (we want). Energy. Good defense. He can change the game on the bases. I’m glad he’s here.”

Who do you want to send to the mound when you need someone to end a long losing streak? How about a guy making his major league debut?

OK, so it’s perhaps a bit unfair for the Nationals to put that kind of pressure on Andrew Alvarez. The 26-year-old left-hander was a 12th-round pick in the 2021 draft, and he’s not among the organization’s top prospects. But he’s nevertheless going to lead his team onto the field at Nationals Park this afternoon, making his big league debut against the Marlins while trying to snap his team’s eight-game losing streak.

Alvarez, who did produce a 2.37 ERA and 39 strikeouts over his last 30 1/3 innings for Triple-A Rochester, will try his best to keep the Nats in the game before handing it over to a bullpen that actually has been really good of late, including nine scoreless innings of one-run ball the last two days against the Rays. He’s one of two September call-ups joining the roster today, with infielder Nasim Nuñez also promoted from Triple-A.

The best thing the Nationals could do to support their rookie hurler? Get on the board first and give him a lead, something they’ve done only once during this losing streak. (And that 1-0 lead didn’t even last a full inning.) The Marlins apparently are going with a bullpen game today, so they’re going to see a bunch of arms, hoping they can do some damage against several of them along the way.

The worst summer in Nationals history came to a close this afternoon in much the same fashion as far too many ballgames over the last three months played out. A 7-4 loss to the Rays had all the hallmarks of previous losses, from a big hole created by a struggling starting pitcher to a futile attempt by the lineup to make up the big deficit.

In getting swept by Tampa Bay, the Nats saw their losing streak swell to eight games. At no point during the streak have they held a lead at the conclusion of any inning.

The misery extends far past these last eight games, though. The Nationals wrapped up the month of August with a 9-19 record. This after they went 9-15 in July. This after they went 7-19 in June. It’s the first time in club history they’ve failed to win at least 10 games in at least one of the three summer months.

That makes them 25-53 since June 1, a .321 winning percentage that easily ranks as worst in the majors during that extended span and would equate over an entire season to a 52-win pace.

"We were playing good," interim manager Miguel Cairo said, citing a recent 5-3 stretch against the Mets and Phillies. "It's not like they've given up or anything like that. They're battling. They're fighting. Today I told them: (25) more games. You've got to keep fighting. You've got to finish strong."

Andrew Alvarez will make his major league debut Monday afternoon against the Marlins, the 26-year-old left-hander set to be promoted by the Nationals from Triple-A Rochester to take the rotation spot that opened up when MacKenzie Gore landed on the 15-day injured list.

Interim manager Miguel Cairo announced the decision this morning, with Alvarez filling one of two allotted September call-up slots for the Nats. The other, a position player, will be announced prior to Monday’s game.

Alvarez doesn’t rank among the organization’s top 30 prospects, but he has outperformed expectations throughout most of his minor league career. Named the organization’s Pitcher of the Year in 2023 after posting a 2.99 ERA and 1.168 WHIP for Single-A Wilmington and Double-A Harrisburg, he reached Triple-A last season and has spent all of this season with Rochester.

Though his overall 2025 numbers (3-7, 4.10 ERA, 1.350 WHIP in 25 starts) don’t sparkle, Alvarez has stepped up his performance in recent weeks. Over his last six starts, he’s 3-0 with a 2.37 ERA and 39 strikeouts in 30 1/3 innings. He last pitched for the Red Wings on Tuesday, which lines him up to start Monday afternoon at Nationals Park on five days’ rest.

“He’s been one of the most consistent pitchers in Triple-A,” Cairo said. “He throws strikes, and that’s something I like. He was Pitcher of the Year, I think, a couple years ago. We want someone that can throw strikes. When you’ve got someone that can throw strikes and keep us in the game, that will be awesome.”

The Nationals have endured three losing streaks of at least seven games this season, which is not typically a sign of a good season. This current losing streak has seen them score a total of 16 runs, only five in their last four games.

So the focus heading into this afternoon’s series finale against the Rays has got to be offense, and how this lineup can somehow find a way to generate something at the plate, especially early on in an attempt to take a lead instead of trying to play from behind yet again.

The problem: The Nats will be facing a left-hander in Ian Seymour who just tossed five scoreless innings of one-hit, eight-strikeout ball against the Guardians in his last start. Seymour, drafted in 2020 out of Virginia Tech, is exactly the type of opposing starter who has given this team fits all year long. He actually throws more changeups (34.9 percent) than fastballs (30.8 percent) and nobody has produced an extra-base hit off that changeup yet this season.

Brad Lord, meanwhile, gets the nod for the Nationals, looking to bounce back from a rare dud, in which the rookie right-hander gave up seven runs in 4 1/3 innings at Yankee Stadium. Over his last two starts, Lord has seen his ERA jump from 3.26 to 3.84.

A crowd of 26,148 at Nationals Park spent all afternoon looking for a reason, any reason, to cheer for the home team.

The home team provided few such moments. The only significant crowd reactions for most of the day, if you want to call them that, came when security guards corralled and escorted two fans who ran onto the field in separate incidents during the course of the Nationals’ 4-1 loss to the Rays.

Such disruptions have been incredibly rare in the 18 seasons of the ballpark’s existence. Far less rare: Tepid offensive performances like the one the Nats put on display today during their seventh straight loss.

Though they narrowly avoided getting shut out for the 12th time this season thanks to an eighth-inning run, the Nationals never came close to mounting any kind of serious threat against Tampa Bay’s pitching staff until that point. Through seven innings, they totaled one hit and four walks, nothing else. They never put more than one runner on base in any individual frame, going 0-for-4 with runners in scoring position one day after going 0-for-12 in those situations in the series opener.

"It's about preparation," interim manager Miguel Cairo said. "We still have young kids. Young, talented baseball players here. They're learning. But you've got to go out there and execute your plan. The pitchers don't dictate what you're going to swing, first of all. You've got to have a plan. If it's not your pitch, OK, let it go. But if it's in the strike zone, you've got to be ready to hit."

Through good times and bad times, MacKenzie Gore has shown an ability to keep himself healthy and on the mound for the better part of three seasons now. But when the left-hander’s arm didn’t feel right in the wake of his last start, he conceded it was finally time to take a break. One he believes will be brief.

The Nationals placed Gore on the 15-day injured list today with left shoulder inflammation, an unexpected announcement but one that might in some way explain the 26-year-old’s struggles since the All-Star break.

Gore said his shoulder didn’t recover the way it normally does after Tuesday’s start at Yankee Stadium, which prompted the club to schedule an MRI.

“You always feel discomfort, especially going into September. It’s just recovering, it wasn’t right,” he said. “So we needed to get it checked out. We made a good decision; we got on it early. I should be alright.”

Gore said “nothing crazy showed up, like a significant injury” on the MRI. The Nationals are simply referring to it as inflammation in his shoulder. Though admitting the IL stint is necessary, the lefty expressed confidence it won’t be a long stint and insisted this won’t end his season.

It is an absolutely spectacular Saturday afternoon in the nation’s capital. I don’t know what we did to deserve this sustained fine weather in late-August, but eternal thanks to whomever is responsible for it. Now, can the home team make it worthwhile for everyone who comes to Nationals Park for this game?

The Nats are mired in a six-game losing streak, one that has featured several frustrating losses, but perhaps none as frustrating as Friday night’s series opener against the Rays. Despite totaling 12 hits and four walks, they scored only one run because they went 0-for-12 with runners in scoring position. Obviously, that won’t cut it in any situation. They have to be better today against right-hander Ryan Pepiot and the Tampa Bay bullpen.

Speaking of people who need to be better, Jake Irvin desperately needs a bounceback performance. It’s too late to salvage this month (0-4, 9.55 ERA) but perhaps the right-hander can at least end it on a high note and head into September feeling better about himself.

And the Nationals need someone in the rotation to step up and finish the season strong, because they just announced their most significant injury in a while: MacKenzie Gore has been placed on the 15-day IL with left shoulder inflammation. We’ll find out more shortly, so please check back for the full article before today’s game, but clearly this is not good news, especially at this late point in the season. Mason Thompson was recalled from Triple-A Rochester to take Gore’s roster spot for now.

PHILADELPHIA – When James Wood grounded into a double play with the bases loaded in the top of the eighth Sunday afternoon, there was plenty of reason for the Nationals slugger to be disappointed in himself. That 4-6-3 twin-killing may have brought home his team’s first run of the day, but it spoiled a golden opportunity to score a lot more than that during what wound up a 3-2 loss to the Phillies.

The real surprise about Wood’s at-bat, though, was the fact he actually made contact yet didn’t record a hit in the process.

In one of the stranger weekend performances you’ll ever see, Wood finished the series 4-for-12 with one walk and seven strikeouts. Do the math, and you’ll figure out the unusual part of this: Every batted ball he produced turned into a hit, until that killer ground ball to second. He struck out in every other at-bat.

Wood has worked hard to snap himself out of the prolonged slump he was mired in through most of July and into the early stages of August. He entered Sunday’s game batting .304 with an .886 OPS over his previous 14 games, looking much more like the best version of himself from the season’s first half.

But he’s not all the way back. Because while Wood is finally hitting the ball hard again, he’s not hitting the ball enough overall, leading to a gargantuan strikeout total.

PHILADELPHIA – Three-fifths of the Nationals rotation is giving them a chance to win right now. The other two-fifths is not, and that has become a real problem.

While MacKenzie Gore, Brad Lord and Cade Cavalli have offered the organization legitimate reason for short-term and long-term encouragement with their pitching performances, Jake Irvin and Mitchell Parker haven’t come close to matching their teammates’ numbers. It would be one thing if those two were at least gutting out five or six innings and keeping the score close, but even that has become a challenge.

It happened to Parker during Saturday night’s loss to the Phillies. And it happened to Irvin this afternoon during a 3-2 loss to the National League East leaders.

It certainly didn’t help matters that the Nats lineup was rendered helpless by Philadelphia left-hander Ranger Suárez, who struck out a career-high 11 batters over seven scoreless innings. But Irvin’s inability to complete even three innings made it feel like this game was much more one-sided than it actually was.

This is the recurring theme for the Nationals at this stage of the season. Over the last 2 1/2 weeks, they’ve gone 7-2 in games started by Gore, Lord and Cavalli while going 1-7 in games started by Irvin and Parker.

PHILADELPHIA – Riley Adams could only laugh when presented with the question: When’s the last time he batted third?

“I don’t know,” the Nationals catcher replied. “Maybe in the minors last year?”

He’s right. Adams actually batted third for the Rochester Red Wings in their final game of the 2024 season, capping off a frustrating season that saw him twice demoted to Triple-A following prolonged periods of struggle in the big leagues.

And the way this season began, Adams could’ve found himself confronting that situation again. As recently as June 23, he was the not-so-proud owner of an .097 batting average and .383 OPS, numbers that could have left his career hanging in the balance.

But with the opportunity to start playing more consistently after Keibert Ruiz landed on the seven-day concussion injured list, Adams has resurrected his season. And it has all come together this month, leading to a .320/.404/.480 slash line in August that has raised his season batting average to .207 and his OPS to .641.

PHILADELPHIA – Good morning from Citizens Bank Park, where the Nationals and Phillies meet for the final time this season. A win today and the Nats would take the series, no small feat. They’d also finish the season series 6-7 against the top team in the National League East. All things considered, that’s not bad at all.

The preeminent storyline today: Can Jake Irvin get himself back on track and give his team a chance? The right-hander is in a serious rut right now, going 2-5 with a 7.36 ERA over his last 10 starts, raising his season ERA from 4.18 to 5.30. Home runs and walks have killed Irvin: He’s served up 2.3 homers and issued 4.2 walks per nine innings during that stretch.

The Nationals haven’t seen Ranger Suárez at all this season, so who knows what to expect when they face the Phillies left-hander? Suárez is having a good season (9-6, 3.25 ERA, 1.168 WHIP), but the Nats did get to him last year for eight runs and 11 hits in eight innings spread over two starts. Something else to consider: If the game is close late, will the Phillies have Jhoan Duran and top lefty reliever Matt Strahm available? Each pitched in the first two games of the series, so it’s possible each is unavailable this afternoon.

PHILADELPHIA – They gave themselves another chance at another dramatic rally inside a sold-out Citizens Bank Park, in spite of the large hole Mitchell Parker dug for his teammates. The Nationals chipped away at the big deficit, got themselves to within two runs and had a chance to tie the game (or even take the lead) late against the Phillies' bullpen for the second straight night.

Perhaps it’s a good reminder just how special Friday night’s come-from-behind win was, though. These things generally don’t happen every night. And, in fact, it didn’t happen again tonight, the Phillies hanging on for a 6-4 victory to even the weekend series and set up a rubber match here Sunday afternoon.

The Nationals, who stormed back in the top of the ninth against Jhoan Duran in the opener, couldn’t make lightning strike twice, though they sure gave it a try. Brady House doubled and Robert Hassell III singled with one out off the All-Star closer, bringing the big boys to the plate representing the go-ahead run. But Duran managed to strike out James Wood and get CJ Abrams to line out to left to end the game and secure his seventh save in eight tries since his acquisition from the Phillies.

Few opponents have proven as tough on Duran as the Nats, though, who have now faced him six times in the last four weeks alone (the first two when he was still with the Twins). They've managed to bat .381 (8-for-21) against him, dramatically better than the .199 mark the rest of the sport has against him this year.

"I think we know we can beat this guy," Hassell said. "We know that anyway, but actually seeing it last night, coming into tonight, we were pretty confident."

PHILADELPHIA – Add another name to the list of Nationals position players getting a crash course at first base: Luis García Jr.

García has been taking grounders and scooping short-hop throws at first base in recent days, learning the nuances of the position from interim manager Miguel Cairo. He’s not ready to appear there in a game yet, but he’s admittedly handled his work there so far well.

“I feel comfortable,” García said, via interpreter Mauricio Ortiz. “Going into it, I think I feel more comfortable than what I expected.”

Originally a shortstop coming up through the minors – and briefly in the majors in 2022 – García made the full-time move to second base later that year and has remained there since. But while his offensive production ticked up, his defensive work diminished. After rating well with 5 Outs Above Average last season, he has plummeted to minus-7 OAA this season, ranking among the worst second basemen in the majors.

With the organization still searching for a long-term answer at first base, García has become the latest current major leaguer to get a look over there. Though Josh Bell has taken over the primary starting job since the Nats designated Nathaniel Lowe for assignment, Cairo has also used utility infielder Paul DeJong and recent Triple-A call-up Andres Chaparro at first base. Catcher Keibert Ruiz, on the 7-day concussion injured list nearly two months, has been getting some work there before games.

PHILADELPHIA – One of the Nationals’ best wins of the season was made possible by Dylan Crews and Daylen Lile’s offensive and baserunning exploits in the top of the ninth, not to mention by PJ Poulin’s two perfect innings of relief to close out an unexpected, 5-4 victory. But none of that would have been possible if not for Cade Cavalli’s quality start, which underscores an important point.

Three of the Nats’ five starters are giving them a chance to win right now. The other two are not. During this nice run against the Phillies and Mets, the team has gone 5-1 in games started by either Cavalli, MacKenzie Gore or Brad Lord, but 0-2 in games started by Mitchell Parker or Jake Irvin. And guess who starts the final two games of this series?

Parker has got to give the Nationals more than he has of late. The lefty has allowed 22 earned runs over his last 16 innings, the team going 0-4 in those starts. His ERA has skyrocketed to 5.83. And when he faced these same Phillies six days ago, he didn’t even make it out of the second inning. Somehow, some way, Parker has to figure out how to at least give his team a chance tonight.

The good news: The Nats beat up on Aaron Nola the same day the Phillies were beating up on Parker. They scored six runs off the veteran right-hander, all of them coming in the third inning, to knock him out of the game. They will be looking to do the same tonight, and perhaps provide enough run support to make up for a potentially shaky start by Parker.

PHILADELPHIA – PJ Poulin wasn’t part of the Tigers’ trade package for Kyle Finnegan, but he might as well have been.

When Detroit acquired Finnegan from the Nationals at the trade deadline for minor leaguers Josh Randall and R.J. Sales, another transaction was necessary to clear a 40-man spot for the veteran reliever. The odd man out wound up being Poulin, who was pitching well at Triple-A Toledo but was deemed expendable and thus was designated for assignment.

The Nats, of course, swooped in and claimed the 29-year-old left-hander off waivers, then surprised him by sending him not to Triple-A Rochester but straight to Washington to join a big league roster for the first time in his career.

Poulin, an 11th-round pick of the Rockies in 2018 out of the University of Connecticut, was stunned just to be in the majors. Three weeks later, could he have believed he would find himself on the mound in the bottom of the ninth at Citizens Bank Park, trying to close out a one-run win in front of a sellout crowd of Phillies fans?

“Uh, I mean … no,” he said with a laugh after contemplating how ludicrous that notion would have sounded at the time. “This has been like the best three weeks of my life.”

PHILADELPHIA – The lights went down at Citizens Bank Park, the cell phones turned on and a sellout crowd of 44,757 roared as Jhoan Duran entered from the bullpen for the top of the ninth. There may be no more imposing scene in baseball right now, and here were the young Nationals forced to confront it head-on.

And confront it they did, with their most impressive rally of the season and arguably their best win in a very long time.

Behind clutch hits and aggressive baserunning from rookies Dylan Crews and Daylen Lile, the Nationals took down Duran, scoring the tying and winning runs en route to a 5-4 victory that left this ballpark stunned and left the visitors’ dugout in jubilation.

"This is what playoff baseball is all about," said Crews, who has seen the Nats go 27-26 in the games he's played this season, compared to 26-49 when he sat or was on the 60-day injured list. "If we want to get to where we want to get to, we have to play in environments like this. ... This is playoff baseball."

Trailing by a run when they came up to bat in the ninth, having already squandered opportunities with runners in scoring position each of the previous three innings, the Nats finally converted against one of the best closers in the sport. And they did it behind the efforts of two rookie outfielders.

PHILADELPHIA – As Bob Carpenter enters the home stretch of his final season behind the microphone, plans are coming together to honor the retiring broadcaster at Nationals Park.

The Nationals announced today they will honor Carpenter prior to their Sept. 27 game against the White Sox, the penultimate game of the season.

The club will hold a retirement ceremony on the field beginning at 3 p.m. (first pitch is scheduled for 4:05 p.m.), with a video tribute, messages from former players and colleagues and a special gift presentation. Carpenter’s name will be unveiled on the façade underneath the broadcast booth, where it will become a permanent fixture.

The first 10,000 fans in attendance will receive a commemorative “See! You! Later!” T-shirt honoring Carpenter’s signature home run call, and a limited number of special game scorecards will be available as well, reflecting the scorebook he has self-published for decades that has become the industry standard for baseball broadcasters at every level of the sport.

The weekend series also will feature the return of the “See You Tater” concessions concept at the “Change-Up” Food Hall in the center field plaza.

PHILADELPHIA – How about that surprising homestand? The Nationals wound up going 4-3 against the Phillies and Mets, looking pretty sharp in the process against the top two teams in the division. So what’s up next? How about a road trip to … Philadelphia and New York!

They won’t be facing the Mets again; this trip concludes at Yankee Stadium, not Citi Field. But first up, it is a rematch with the Phillies over the weekend, the Nats hoping to keep the good vibes going in a very familiar matchup.

Cade Cavalli looked great six nights ago against this same lineup, tossing seven scoreless innings on 90 pitches to earn his first major league win. It’s an entirely new challenge, though, to face the same team again, especially in back-to-back starts. Surely, the Phillies picked up on something about Cavalli in the first meeting. It’s up to the rookie right-hander (and the Nationals coaching staff) to figure out what, if any, adjustments he needs to make in the rematch.

Cavalli outdueled Taijuan Walker in that Saturday afternoon affair on South Capitol Street, and that’s who the Nationals are facing again tonight. The veteran right-hander allowed two runs over 6 2/3 innings, the big blow a two-out, two-run double by James Wood in the bottom of the fifth that accounted for all of the runs scored in the 2-0 victory.

The Nationals signed Shinnosuke Ogasawara over the winter believing the 27-year-old left-hander – the first Japanese free agent signing in club history – could become a viable major league starter, or at worst provide ready-to-go rotation depth at Triple-A Rochester.

The plan never was to use him as a reliever. Certainly not as a late-inning, high-leverage arm.

Funny how plans change. Because over the course of the last two weeks, Ogasawara has found himself pitching in a most unexpected role. And thriving in it.

Wednesday night provided the most dramatic example yet. Handed the ball for the top of the seventh with the Nats leading the Mets by one run, Ogasawara proceeded to retire Francisco Lindor, Juan Soto and Starling Marte in order, preserving a 5-4 lead that wound up holding through the game’s final out.

“He’s on a mission,” interim manager Miguel Cairo said. “I love the passion, the energy. That’s what you’re looking for when you put someone on the mound.”
