PITTSBURGH – It’s been an exciting day for the Nationals so far after they officially announced a multi-year contract extension with longtime general manager Mike Rizzo this morning. The excitement continues tonight with the debut of a top prospect.

Jackson Rutledge will make his major league debut tonight as the starting pitcher for the Nationals. The 2019 first-round pick, who dealt with various injuries to begin his professional career, is 8-4 with a 3.71 ERA and 1.269 WHIP in 119 innings over 23 starts this year between Double-A Harrisburg and Triple-A Rochester, his first time reaching the upper levels of the minor league system.

A former top prospect and currently the Nationals’ No. 7 prospect per Baseball America and No. 13 per MLB Pipeline, the big right-hander will be the 10th player and sixth pitcher to make his major league debut with the Nats this season. He follows Thaddeus Ward, Hobie Harris, Jake Irvin, Jake Alu, Amos Willingham, Jose A. Ferrer, Blake Rutherford, Jacob Young and Drew Millas.

The Nationals have optioned Mason Thompson to Triple-A Rochester to make room for Rutledge on the active roster.

PITTSBURGH – The Nationals got a great start from Patrick Corbin last night to end a long stretch without length from their starter. Is it too much to ask for a second in a row?

Joan Adon will try to provide the Nats with back-to-back quality starts for the first time in a while. Since rejoining the rotation as the sixth man, the right-hander is 2-1 with a 5.59 ERA over six outings. He has tossed two quality starts, each coming in his two road starts in Cincinnati and Miami. Although he struck out six in his last start, he gave up two runs in five innings on 80 pitches.

Offensively, the Nats took the lead first last night for the first time in two weeks, led by CJ Abrams’ first multi-homer game and another homer from Dominic Smith. Again I ask, is it too much to ask for a second in a row?

PITTSBURGH – Hello from PNC Park, where this reporter is making his first trip to this beautiful ballpark! I’ve heard a lot of great things about this stadium and it certainly lives up to the hype.

After a 2-7 homestand, the Nationals will try to reverse their fortunes as they embark on their penultimate road trip of the season. The Nats have played well on the road recently, going 6-4 over their last 10 games away from Nationals Park.

Patrick Corbin will look to become the Nats’ first 10-game winner since 2019, when he, Stephen Strasburg, Max Scherzer and Aníbal Sánchez all won double-digit starts. Oh, how times have changed since Corbin won 14 games in his first year with the Nats, now the owner of a 9-13 record and 5.23 ERA this season.

Corbin gave up three runs over 5 ⅓ innings while taking the loss in the first game of a doubleheader against the Pirates on April 29. But he’s 2-1 with a 2.31 ERA in six career starts at PNC Park.

The Nats dropped two of three to the Pirates that weekend in April, getting outscored 24-11.

BOSTON – The Orioles have reached the end of their three-city road trip with a chance today to register their 10^th sweep.

The club has won seven games in a row and 16 of 20. The magic number for clinching a postseason berth is down to five. The lead over the second-place Rays is four.

Jordan Westburg is out of the lineup today after leaving last night’s game in the seventh inning. Manager Brandon Hyde hinted that Westburg is dealing with some soreness but didn’t specify.

Aaron Hicks is in right field. Adam Frazier is the second baseman. Ramón Urías is at third base.

His brother, Luis, is playing second base for the Red Sox.

Hey, you know what would be great? If the Nationals and Dodgers could play a ballgame today that starts on time and isn’t interrupted by rain at any point. Wouldn’t that be just lovely?

It’s possible that wish will come true, if the storm that’s passing through town this morning clears out in time for a 1:35 p.m. first pitch. Keep your fingers crossed.

The Nationals have a shot at a series win after Saturday night’s bonkers, 11-inning victory via a walk-off wild pitch. The bullpen is not in great shape at this point, so there really is pressure on Trevor Williams to bounce back from a bad start last time out and give his team a chance. Considering the lineup he’s facing, that’s a tall task.

The Nats have been scoring some runs this weekend, so that’s a good thing. And they’ve hit for some power, which is also a good thing. We’ll see if they can keep that up this afternoon and emerge with what would have to be considered an impressive series win over one of the best teams in baseball.

After a long night that included a 3-hour, 8-minute game and a 1-hour, 34-minute rain delay, the Nationals and Dodgers are back at it this afternoon for the second game of their weekend series. The Nats have lost nine of their last 11 and sure could use a win.

They also sure could use a start longer than four, or ideally five, innings. They’ve put way too much strain on an already tired bullpen the last couple weeks, and Davey Martinez wound up using six relievers Friday night. So the pressure’s on Jake Irvin to do what he’s actually done with some regularity this season and provide length. Against a tough Dodgers lineup, that’s a stiff challenge.

Martinez does have another available reliever today in Joe La Sorsa, who was recalled from Triple-A Rochester when the Nationals placed MacKenzie Gore on the 15-day injured list with blisters on his finger. Stay tuned for more on that story.

BOSTON – The Orioles are a season-high 37 games above .500 and four games ahead of the Rays in the American League East as they reach the final stage of their road trip at Fenway Park.

They’ve won five in a row, seven of nine, 11 of 14, 14 of 18 and 25 of 35. On the line this weekend is a streak of 84 consecutive multi-game series without being swept.

Gunnar Henderson is the shortstop tonight against the Red Sox. Ryan O’Hearn is batting cleanup as the designated hitter, followed by first baseman Ryan Mountcastle.

Austin Hays is in left field. In 18 games since Aug. 15, Hays is batting .338/.413/.646/1.059 with eight doubles, four homers and 13 RBIs.

Adam Frazier is playing second base and Ramón Urías is at third.

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.

The Nationals need to win a game. Doesn’t matter how. Doesn’t matter who does it. They just need to win a game for the first time in eight days.

They can get there with a quality pitching performance from Joan Adon, who has offered up a couple of those in five starts since returning to the big leagues last month: once against the Reds, once against the Marlins. This is the first time Adon has faced the Mets this year after two matchups last year in which he allowed seven runs in eight total innings.

The Nats were going to face Carlos Carrasco tonight, but the veteran right-hander is out for the season after a 50-pound barbell fell on his pinky finger and broke it. So instead the Mets send right-hander José Butto to the mound for only his fourth career start. One of those came against the Nationals back on April 25, when he issued six walks in 4 2/3 innings and took the loss.

Ryan McKenna is playing center field tonight in the latest Orioles right-handed heavy lineup in Anaheim.

Austin Hays is the cleanup hitter and left fielder. Jordan Westburg is starting at second base. Jorge Mateo is the shortstop.

Aaron Hicks is in right field, with Anthony Santander serving as designated hitter.

Adley Rutchman is back in the leadoff spot and catching.

Gunnar Henderson is too good to sit in any lineup. He’s the third baseman.

The Nationals don’t have to face the Marlins anymore this season, and if that isn’t cause for celebration, what is? Tonight they open a two-game series with the Mets, the last time they’ll face New York this year. A sweep would give the Nats the season series at 7-6; one loss would give it to the Mets (if you care about such things).

This would’ve been MacKenzie Gore’s turn in the rotation, but the Nationals are giving the left-hander time to get himself ready after returning today from bereavement leave. (Joe La Sorsa was optioned to Triple-A Rochester.) So it’s Patrick Corbin on the mound, well rested himself because his last start came Wednesday in Toronto.

The Nats face a very different Mets rotation from the last one they faced, with Max Scherzer and Justin Verlander now due to pitch against each other Wednesday night in a huge showdown between the Rangers and Astros. It’ll be Jose Quintana for New York tonight; the veteran lefty has not faced the Nationals yet during an injury-plagued season.

The Orioles begin their series in Anaheim tonight with Adley Rutschman out of the lineup for the second time in six games.

The Angels are starting three left-handers, and Austin Hays moves into the leadoff spot tonight. Gunnar Henderson is playing third base and batting cleanup.

Jordan Westburg is playing second base and batting fifth. Jorge Mateo is the shortstop.

Aaron Hicks is in right field, and Anthony Santander is the designated hitter.

Rookie Grayson Rodriguez has allowed 11 runs in his last seven starts over 42 2/3 innings. He faced the Angels on May 15, before his reset, and allowed eight runs and nine hits in 3 1/3 innings. Shohei Ohtani and Chad Wallach homered in the fourth.

Here’s some good news for you on this Sunday morning: This is the last time the Nationals will face the Marlins this season. Here’s some bad news: They’ve got to face Sandy Alcantara in today’s series finale, trying to avoid a four-game sweep and trying to avoid falling to 2-11 against Miami this year.

Alcantara isn’t having a Cy Young season; he’s 6-12 with a 4.23 ERA. And the Nats did hit him around the only time they faced him this year, scoring five runs on 10 hits back on June 16. They’ve got a very different lineup right now, though, with several young players who have never faced the electric right-hander before. We’ll see how they fare against him.

Josiah Gray gets the start for the Nationals, and this is an important one for him, no matter the opponent. Gray lasted only two innings in Toronto on Monday night, pulled after throwing a whopping 63 pitches. He has not been the same guy he was in the first half of the season, and he’s suddenly in danger of seeing all the good things he did earlier get lost in the shuffle with a rough finish. A bounceback performance today against a Miami team he held to one earned run over seven innings back in June would be wonderful.

Ryan Mountcastle is out of the Orioles lineup again tonight in Arizona. He was scratched last night due to an illness.

Gunnar Henderson, who went 2-for-4 last night with two runs scored, stays at shortstop. Adley Rutschman is the designated hitter.

Ryan O’Hearn is the first baseman and Ramón Urías is playing third base. Adam Frazier is the second baseman.

Henderson is batting .330 or better when he’s ahead or even in the count, but .172 when behind.

Anthony Santander is slugging .809 against fastballs since the start of August after slugging .276 against them in July.

One bad week isn’t going to undo everything positive the Nationals have done over the previous six weeks. But you’d sure rather not let this losing streak linger much longer, right? They’ve dropped three in a row, not to mention five of their last six, for the first time since the first week of July.

They’ll try to reverse that trend this afternoon against a Marlins team that continues to beat them with far more regularity than anyone around here would prefer. Aside from a solid couple of days in Miami last weekend, the Nats have been abysmal against their division foes: 2-9 this season, 6-24 over the last two seasons.

A lineup that has struggled but did manage three solo homers Friday night will be facing veteran Johnny Cueto, whose season has twice been disrupted by stints on the injured list, once for biceps tendinitis and most recently for a viral infection. What the crafty 37-year-old, who was roughed up in his last four starts before getting sick, has left in the tank is anyone’s guess.

Trevor Williams gets the start for the Nationals, hoping to build off back-to-back strong outings against the Phillies and these same Marlins. He allowed only two runs and went seven innings Sunday in Miami, taking a tough-luck 2-1 loss. After using six of his seven relievers during Friday’s 11-inning loss, Davey Martinez could certainly use a comparable start today from Williams.

As well as they played for a good six weeks, the Nationals are kind of slipping a bit of late. They’ve lost four of their last five games, and a big part of the problem has been a lack of offense. The Nats have scored only 10 runs over those five games, totaling 30 hits, only six of those for extra bases. More, obviously, is needed.

The return of Lane Thomas to the lineup after missing Thursday’s game with a tight back would help, though he’s been slumping himself. Perhaps newly promoted outfielder Travis Blankenhorn, called up from Triple-A Rochester this afternoon, will provide a spark and some power.

Jake Irvin gets the start for the Nationals, and he quietly has become their most consistently effective starter. Over his last 13 outings, the rookie right-hander has a 3.64 ERA. And he’s allowed two or fewer runs in seven of those starts, often completing six innings. Another such performance tonight against the Marlins would be great.

The Nats have another arm in their bullpen as well, with Amos Willingham recalled from Triple-A as the roster expands to 28 active players. Reliever Rico Garcia, who had been on the 15-day injured list, was released to clear a 40-man spot for Blankenhorn.

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 – It’s a dreary Wednesday here north of the border, so the roof at Rogers Centre will probably be closed for the first time this series as the Nationals and Blue Jays face off one more time. A win today for the Nats would incredibly make it six consecutive series won, eight of their last nine.

And if it’s a matinee series finale, that means Patrick Corbin is pitching, a product of the six-man rotation that has been used for several weeks now. Not that Corbin has been bothered by it. Quite the contrary, he’s been quite good this month, going 2-0 with a 2.70 ERA, the Nats winning three of his four starts. And the left-hander continues to pitch well against American League foes, going 4-0 with a 1.73 ERA against the Mariners, Rangers, Red Sox and Yankees this summer.

After getting a pair of big home runs Tuesday night from Carter Kieboom and Keibert Ruiz, the Nationals will try to keep the offense going today against Chris Bassitt, the former Athletics and Mets right-hander who enters 12-7 with a 4.00 ERA, having surrendered five homers over his last 24 2/3 innings.

The Orioles can exceed last year’s win total of 83 with a victory today over the White Sox, in a game that concludes their homestand. They also can register their ninth sweep.

Adley Rutschman is on the bench this afternoon. Gunnar Henderson is leading off and playing third base.

Adam Frazier is in left field, with Austin Hays also working in a reserve role. Jordan Westburg is the second baseman.

Kyle Gibson is seeking his team-leading 14^th win, which also would be a career high. He has 14 quality starts, and he worked eight innings against the Blue Jays in his last outing.

Yoán Moncada is 8-for-22 with three doubles against Gibson. Tim Anderson is 7-for-22 with a double and home run.

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.
