PITTSBURGH – It would be hard to find a more striking difference in ballpark vistas than the one the Nationals just saw in Miami and the one they’ll see the next four days at PNC Park. And the weather here looks great, as well, aside from a chance of rain Friday night into Saturday morning.

The Nats arrive in Pittsburgh after splitting their two-game series with the Marlins, a series that absolutely was there for the taking if they had simply converted in the ninth or 10th innings when they had the chance. Oh well, maybe it was too much to expect a season sweep of a division opponent.

The Nationals haven’t seen the Pirates since way back in early April, the first homestand of the season. A lot has changed for both teams since then, perhaps most notably the promotions of the top two picks in last summer’s draft, the former LSU teammates. Dylan Crews will get plenty of action this weekend, but unfortunately Paul Skenes will not. The Pirates, looking to keep Skenes in the rotation through season’s end, are going to a six-man rotation, so he won’t start again until Monday.

So tonight it’s Jake Irvin for the Nats and Bailey Falter for the Pirates. Irvin needs to bounce back from his bizarre start against the Cubs, when he was torched for seven runs in the top of the second but didn’t give up anything else the rest of his outing. This is an important month for Irvin, who is trying to make sure his outstanding first half doesn’t become an afterthought. He’s facing a Pittsburgh lineup that was no-hit by Shota Imanaga and two Cubs relievers Wednesday night at Wrigley Field.

Falter faced the Nats four times over the last two seasons as a member of the Phillies, and was quite successful, going 2-0 with a 2.57 ERA. The left-hander has been pretty mediocre for the Pirates this year, and he enters this one having allowed four or more runs in three of his last four starts.

MIAMI – After a nice, clean game last night, the Nationals now have a chance to sweep the Marlins in this quick two-game series before heading up to Pittsburgh. A win would also keep their winning streak against Miami alive.

Like Patrick Corbin on Tuesday, MacKenzie Gore is looking to build off two strong starts. He completed six innings of one-run ball against the Braves in Atlanta and then he held the Yankees to two runs over six innings last week. Gore was excellent against the Marlins in his one other start against them this year, holding them to one run with 10 strikeouts over seven frames.

The Marlins are sending out another rookie right-hander in Valente Bellozo. The 24-year-old is 2-2 with a 4.32 ERA and 1.344 WHIP in eight major league starts since debuting in June. Although he has shown flashes of promise (holding the Royals, Reds and Phillies scoreless over a combined 17 ⅔ innings), he also has struggled at times in giving up five or more earned runs in three of his starts, including in each of his last two.

MIAMI – Hopefully, the Nationals used an off-day on Labor Day to reset and forget about this weekend’s series against the Cubs, in which they were swept in three games at home. Maybe spending the rare holiday off-day in the South Florida sunshine is just what they needed.

And what better way to shake off a home sweep than a division rival that you are perfect against this season? That’s right, after struggling against the Marlins over the past couple of years, the Nats enter this quick two-game set 7-0 against the National League East basement-dwellers.

Patrick Corbin will look to extend his streak of back-to-back impressive outings when he takes the ball tonight. Corbin finally earned that elusive 100th career win by holding the Rockies to one run over six innings on Aug. 22. He followed that up with six shutout innings against the Yankees last week. The lefty was roughed up for seven runs (four earned) in four innings when he started here on April 28, but the Nats offense backed him up and stormed back for a 12-9 win.

Max Meyer will make his 11th start of the season for the Fish. The rookie right-hander is 3-4 with a 5.44 ERA and 1.383 WHIP this season. He has yet to face the Nats in his young career and has given up at least four runs in five of his last six starts.

DENVER – Zach Eflin is reinstated from the injured list and starting this afternoon against the Rockies. Coby Mayo is recalled from Triple-A Norfolk as the 14^th position player on an expanded roster.

And that’s just the beginning.

Infielder Ramón Urías is on the 10-day injured list with a sprained right ankle. He’s on crutches again today after rolling the ankle last night on a tag play at third base.

The Orioles selected catcher David Bañuelos’ contract from Norfolk. He was on the taxi squad and likely will return to it by Monday afternoon.

Outfielder Forrest Wall was designated for assignment to make room for Bañuelos. He was 4-for-11 with a home run for Norfolk after the Orioles claimed him on waivers last week from the Marlins.

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.

DENVER – Adley Rutschman is catching tonight and batting second as the Orioles try to secure a series win at Coors field. He was on the field for early hitting.

Gunnar Henderson is leading off and Colton Cowser moves down to fifth. Eloy Jiménez is the designated hitter.

Anthony Santander is in the cleanup spot.

Ramón Urías stays at third base. Jackson Holliday stays in the ninth spot in the order.

The Yankees lost today and lead the Orioles by only one game in the division race.

Friday night was a wild one for the Nationals, who saw Jake Irvin give up seven runs to the Cubs in the top of the second, then Irvin and a parade of relievers give up nothing the rest of the way, then the lineup rally to score three runs in the ninth and put the winning run on base with two outs and Dylan Crews at the plate … only to watch him strike out to end the game. Enough drama for you?

So, what does today’s game have in store? There’s an obvious storyline to watch: DJ Herz facing the Cubs. The rookie left-hander came up through Chicago’s system before he was dealt to the Nats last summer for Jeimer Candelario, and now he gets to face his former team for the first time. Herz has been solid this month, with a 2.22 ERA and 1.192 WHIP, though he’s averaging fewer than five innings per start.

Davey Martinez again has a lineup with Dylan Crews and James Wood at the top and CJ Abrams not near the top. Abrams does move up one spot today, from seventh to sixth, against Cubs right-hander Javier Assad. But clearly his drop down the order Friday night wasn’t simply a matchup situation against a left-hander. This is going to remain this way a while longer until Abrams gets himself back on track.

It’s been a good week for the Nationals. It’s always nice to take two of three from the Yankees, but it’s especially nice to do so with your top prospect making his major league debut and leading the charge with other cornerstone young players.

Now the Nats welcome the Cubs for three games over this holiday weekend. Chicago is barely holding onto hope of a postseason berth, entering this series 9 ½ games back of the Brewers in the National League Central and five games back of the final NL Wild Card spot.

Jake Irvin looks to become the first Nationals pitcher to reach 10 wins this season when he takes the ball tonight. The right-hander will also try to continue a strong streak by Nats starters, who have combined to post a 1.94 ERA and 1.098 WHIP while striking out more than one batter per inning and never once allowing more than two earned runs over the last nine games.

Shota Imanaga will get the ball from Craig Counsell to oppose Irvin on the hill. The 30-year-old Japanese left-hander is in the running for NL Rookie of the Year with a 10-3 record and 3.08 ERA in 24 starts during an All-Star campaign.

LOS ANGELES – The Orioles and Dodgers have split the first two games of this three-game series and tonight's winner will take the series at Dodger Stadium.

Los Angeles (79-54, .594) has the best record in the major leagues and has won seven of nine, 13 of 18 and 16 of its last 23 games. In the 23 games, the Dodgers are scoring 5.1 runs per game with a team ERA of 3.19.

The Dodgers are 44-24 at home and 26-14 versus American League teams.

The O's lineup tonight is a look we've seen a lot versus right-handers with Colton Cowser leading off, Adley Rutschman catching and Gunnar Henderson at shortstop. Eloy Jiménez is the designated hitter and Cedric Mullins is back in center field and batting seventh.

The Orioles (77-57) begin play today one game behind the Yankees, who are off, for the AL East lead with 28 games remaining. The two games this series have been decided by three total runs. The O's have played a lot of close games lately, with seven of their past 10 decided by one or two runs. They are 4-3 in those contests.

LOS ANGELES – Orioles infielder Jorge Mateo, on the injured list since July 25 with a left elbow subluxation, had surgery today and will miss the rest of the 2024 season.

The O's, until this news, held out longshot hope he might return late this year and possibly for the postseason. 

But today he had successful left elbow ulnar collateral ligament reconstruction with internal brace and flexor repair. 

The surgery was performed by Dr. Keith Meister at Trinity Park Surgery Center in Arlington, Texas. 

Mateo has one more year of arbitration eligibility coming this winter and could be a free agent at the end of the 2025 season.

It’s been a fun couple of nights at Nationals Park. Monday night saw the debut of Dylan Crews and the Yankees outplaying the home team during a tight, 5-2 win. Tuesday night saw Crews record his first hit, Andrés Chaparro record his first home run, Patrick Corbin outpitch Gerrit Cole and the Nats emerge with a tight, 4-2 win. The atmosphere in the ballpark has been outstanding, the kind of thing that used to be common around here but hasn’t been common for several years.

Now it’s the rubber game of the series, and a big start for MacKenzie Gore. It’s been a ragged summer for the young left-hander, but he hopes he turned a corner over the weekend in Atlanta, where he held the Braves to one run over six innings without issuing a walk. This is obviously a tough lineup Gore has to face tonight, but he’s unquestionably got better stuff than Corbin, who was hugely successful. It’s up to Gore to make his stuff work against Juan Soto, Aaron Judge and Co.

The Nationals would love to give Gore some significant run support. It’s been a strange few days, because they’ve hit the ball hard quite a bit, and they’ve recorded four homers and four doubles, but they’re a staggering 0-for-17 with runners in scoring position. (The Yankees, by the way, are 0-for-13 in the series.) They’ll go up against left-hander Carlos Rodón, who has been hit-or-miss of late, and try to convert at least a few times in clutch situations to provide Gore some support.

The Nats did make a roster move this afternoon: Orlando Ribalta has been recalled from Triple-A Rochester, with Joan Adon placed on the 15-day injured list with a right shoulder biceps strain. So it's a swap of right-handed relievers.

LOS ANGELES – Center fielder Cedric Mullins is back in the Orioles lineup tonight as they begin their road trip against the Dodgers.

Mullins left Friday's game early with left quad tightness and missed the last two games of the Houston series. He took batting practice before Sunday's game and will make the start tonight.

Ryan O'Hearn, who has not homered since July 20, gets the start at first base after Ryan Mountcastle went on the injured list Monday with a left wrist sprain.

With 30 games left in their regular season, the Orioles have three road trips remaining, the first beginning with their series-opener tonight at Dodger Stadium.

The Dodgers (78-53) have the best record in the major leagues and are 12-4 in their past 16 games. 

The hubbub of Monday night is gone, but that doesn’t mean there won’t still be juice in the ballpark tonight. The Yankees are still here, Juan Soto and Aaron Judge are still here, Dylan Crews and James Wood are still here and there’s a juicy (if lopsided, on paper) pitching matchup on tap as well.

Patrick Corbin vs. Gerrit Cole. The guy who did pitch in relief in Game 7 of the 2019 World Series vs. the guy who did not pitch in relief in Game 7 of the 2019 World Series. The guys whose careers have taken wildly different paths since that night.

Corbin is really facing a gantlet tonight in the Yankees lineup, though for whatever it’s worth he tossed a quality start last summer in the Bronx, allowing three runs over six innings to earn the win. Judge and Gleyber Torres each homered, but that’s all Corbin gave up during that game. It’s also worth noting he allowed one run over six innings to the Rockies last time out, earning career win No. 100.

Cole, meanwhile, seems to have found his groove after spending the season’s first 2 1/2 months on the injured list. He enters this one on a 12-inning scoreless streak, having shut out the Tigers and Guardians. He’ll be going up against a very young Nats lineup that now features Crews, Wood and CJ Abrams.

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.

Triple-A Norfolk outfielder Daniel Johnson is on the Orioles’ 24-hour taxi squad while center fielder Cedric Mullins is reevaluated for left quadriceps tightness.

Mullins exited Friday's game due to discomfort and so far he's avoided the injured list. Johnson was removed from Norfolk’s game after two at-bats that night, and he’s got a locker at Camden Yards in case Mullins’ quad doesn’t improve enough to let him play.

Johnson, also a left-handed bat, is hitting .267/.333/.479 with 17 doubles, a triple, 20 home runs and 70 RBIs in 98 games with Norfolk. He hasn’t played in the majors since 2021 with Cleveland.

The Orioles would need to make a corresponding 40-man roster move to accommodate him.

“A lot of at-bats,” Johnson said when asked to explain his success with the Tides. “Get a lot of at-bats, you can do a lot every single day. So just the ABs. It’s an opportunity.”

ATLANTA – Good morning from Truist Park, where the Nationals and Braves wrap up their weekend series with an extra-early, 12:05 p.m. first pitch today. It’s another “MLB Sunday Leadoff on Roku” game, so you’ll only be able to watch this game via streaming devices. Here’s how you can watch for free.

The Nats have lost two incredibly winnable games the last two nights – 3-2 in 10 innings, 4-2 in regulation – and they should be frustrated by the fact they didn’t win either of those games. They have a chance to rectify that today and finally clinch the season series over Atlanta, something, remarkably, they haven’t done since 2017.

It’s DJ Herz on the mound, and the rookie has been quite good since the All-Star break: a 3.07 ERA and 34 strikeouts in 29 1/3 innings. He faced the Braves in his second career start back in early June and did OK, allowing two runs over 4 1/3 innings, though he needed 87 pitches to do it. The lefty has come a long way since then and will look to continue the upward trend this afternoon.

The Nationals will be facing a familiar face in Reynaldo López, the one-time prospect-turned-All-Star who continues to enjoy a breakthrough season here in Atlanta with a 2.05 ERA and 1.195 WHIP in 20 starts. The right-hander gave up two runs (via solo homers by CJ Abrams and Lane Thomas) over six innings in a June 6 no-decision. Abrams is leading off today, but obviously Thomas is no longer here. Interesting to see Drew Millas behind the plate for this one, with Keibert Ruiz serving as designated hitter and Riley Adams sitting.

ATLANTA – There were a lot of encouraging things about Friday night’s game for the Nationals. Except for the one thing that matters more than anything else: the outcome. Their 3-2, 10-inning loss to the Braves was ugly, with CJ Abrams committing a throwing error to allow the winning run to score.

So, they’ll have to dust themselves off and try to get back on track tonight in the second game of the weekend series, hoping to score more than two runs this time. They’ll be facing a seemingly less daunting opposing pitcher in Charlie Morton, the 40-year-old right-hander with a 4.29 ERA. The Nats have roughed up Morton twice this season, scoring 13 runs on 19 hits in 10 2/3 scoreless innings. Abrams (4-for-9, two homers) has excellent numbers against him, though you have to also note the two others with awful career numbers against him: Luis García Jr. (2-for-16, seven strikeouts) and Joey Gallo (0-for-20, two walks, 16 strikeouts).

Jake Irvin has been outstanding in his two starts against Atlanta this season, totaling 12 scoreless innings with 14 strikeouts. The right-hander is still trying to right his wayward ship overall, though, having posted a 6.20 ERA over his last eight starts, victimized by a whopping 14 homers in the process.

The Nationals did make a roster move this afternoon, officially placing Alex Call on the 10-day injured list with a partial tear of the plantar fascia in his left foot. For now, his replacement is Drew Millas, giving the team three catchers through the rest of the weekend. We’ll have to see what they decide to do Monday when they promote Dylan Crews from Triple-A and have to remove someone from the roster to make room for the top prospect.

ATLANTA – There’s big news today about Dylan Crews, if you haven’t seen it yet, but the top prospect won’t be making his major league debut until Monday. Between now and then, the Nationals have a three-game series with the Braves this weekend, and that’s a challenge in itself, even if Atlanta has been dealing with a ton of injuries and is no longer a shoo-in to make the playoffs.

This is a big start for MacKenzie Gore, whose once-promising season has been slipping away over the last two months. In his last 10 starts, the left-hander is 1-5 with a 7.09 ERA, with an ugly 38-to-29 strikeout-to-walk ratio. He’s got to find a way to throw strikes tonight, but he’s also got to find a way to throw quality strikes, keep his pitch count down and at least get through five innings having given his team a chance.

The challenge is no easier for the Nationals at the plate, because they have to face Chris Sale. The likely National League Cy Young Award winner frontrunner at this point with a 14-3 record and league leading 2.62 ERA. One of those losses, though, did come to the Nats back on June 7, when Sale allowed only two runs over seven innings but was outdueled by Jake Irvin in a 2-1 victory.

Cedric Mullins is in center field tonight after being absent from the lineups in Queens.

Colton Cowser is playing left field and Ryan O’Hearn is in right. Anthony Santander is the designated hitter.

Adley Rutschman is batting fifth. Jackson Holliday is seventh.

Gunnar Henderson is slugging .717 in 28 games against the American League West this season.

The Orioles have homered in 16 consecutive games, tied for the third-longest streak by any team this season behind the Twins (28) and Orioles (22 straight in June) per STATS.

It’s another surprisingly gorgeous August day here in the nation’s capital, where the home team has a shot at a series win if it can beat the Rockies again this afternoon. The Nationals won Wednesday night in convincing fashion, thanks to an effective and efficient start from Mitchell Parker and a consistent offensive attack highlighted by Luis García Jr.’s three-run homer.

Can Patrick Corbin duplicate Parker’s seven innings of one-run ball? That might be a bit too much to ask out of the veteran left-hander, who for the sixth straight start will be taking the mound in search of his 100th career win. (He entered the season with 97, by the way.) Corbin did enjoy back-to-back quality starts a month ago against the Reds and Padres. In four starts since then, he sports a 10.38 ERA, with 21 runs allowed in only 17 1/3 innings.

The Nats did a nice job at the plate Wednesday night against Rockies right-hander Tanner Gordon. They’ll try to keep that up today against right-hander Cal Quantrill, who did toss a quality start against them two months ago at Coors Field. Quantrill has struggled since then, though, with a 7.23 ERA over his last eight games, with 10 homers surrendered in that time.
