Ryan O’Hearn is in right field again tonight, as the Orioles continue their series against the White Sox.

Gunnar Henderson is the shortstop and Adam Frazier is playing second base. Jordan Westburg stays on the bench.

Austin Hays returns to left field.

Anthony Santander, serving as designated hitter, is the first Orioles switch-hitter with at least 25 home runs in consecutive seasons since Eddie Murray in 1987-88.

Henderson is one stolen base shy of becoming the first rookie in team history and 20th in major league history with at least 20 doubles, five triples, 20 homers and 10 steals in a season.

TORONTO – Hello from Rogers Centre, up here north of the border. The Nationals are making their first trip to Canada since 2018, having technically played road games against the Blue Jays in both 2020 and 2021 even though both series were played at alternate sites due to COVID travel restrictions (2020 at Nationals Park, 2021 in Dunedin, Fla.).

This is the final leg of a four-city trip for the Nats that began eight long days ago in Williamsport, Pa., then continued to New York and Miami. They’ve gone 5-2 so far, so even if they got swept here they’d still head home with a .500 record. Not that anyone wants that to be the outcome.

You would think the Nationals will need to score a few more runs than they did in Miami, because Toronto’s lineup is more potent. The Nats have Keibert Ruiz back in the lineup, batting cleanup and catching for the first time since Wednesday at Yankee Stadium. They’ve also got three catchers on the roster for the first time this season, officially promoting Drew Millas from Triple-A Rochester.

Josiah Gray gets the start, hoping for similar success to that he had at Yankee Stadium (one run, one hit) while being a bit more efficient (five walks). Gray will need to avoid hard contact, because the ball flies here at Rogers Centre.

MIAMI – Remember that time earlier this year when the Nationals were searching for their first series sweep in over two years to break the longest major league streak without one?

Well, here they are now in search of their fourth series sweep since the All-Star break. Oh, and have we mentioned the fact that the Nats are only four games behind these Marlins in the National League East and only seven games back from a Wild Card spot?

Trevor Williams will lead the charge as he looks to follow up one of his best starts of the season. He pitched six shutout innings of two-hit ball against the Phillies in Sunday’s Little League Classic. He’s 0-1 with a 6.97 ERA and 1.548 WHIP in two starts against the Marlins this year, including giving up three runs with five strikeouts over six innings in a start here in May.

Right-hander JT Chargois will start a bullpen game for the Fish. He’s 1-0 with a 3.56 ERA and 1.154 WHIP in 32 appearances this year. After pitching a scoreless ninth inning Friday, he has four shutout outings against the Nats in his career.

MIAMI – The Nationals finally got the monkey that is the Marlins off their backs last night. The 7-4 victory was their first against the Fish this year, and first in Miami since last season.

Now they can focus on playing ball and winning a series.

Jake Irvin will look to make it three straight strong starts when he takes the hill this afternoon for the 20th outing of his rookie season. He’s allowed just two runs in 12 ⅔ innings over his last two starts against the Athletics and Phillies. At 3-5 with a 4.47 ERA and 1.397 WHIP on the year, the right-hander held the Marlins to one run in five innings during a home start on June 17.

Electric right-hander Eury Pérez makes his 15th start of his rookie season, where he has gone 5-4 with a 2.91 ERA and 1.074 WHIP. He pitched six shutout innings with 10 strikeouts his last time out against the Dodgers, and held the Nationals to one run over five innings with six strikeouts in his second career start in May.

MIAMI – Hello from outside downtown Miami, where the Nationals continue their inconvenient road trip up and down the North American East Coast. After starting north to Williamsport and New York, they headed to South Beach before going back north of the border to Toronto.

Rack up those miles.

The Nats have been playing great ball lately, winning nine of their last 12 games. But now they return to a place where they haven’t won a whole lot to face a team they have yet to beat this season. The Nats are 0-6 against the Marlins this year, including going 0-3 here in May. They are 4-21 against the Fish dating back to last year and are 2-10 at loanDepot Park since the beginning of last season.

Joan Adon will make his fourth start since rejoining the Nats rotation. He’s 1-0 with a 7.62 ERA and 1.154 WHIP over his last three. Amazingly though, the Nationals have won all three of those starts despite some rough performances over his last two. Adon is 0-2 with a 10.57 ERA and 1.826 WHIP in two career starts against the Marlins, both of which have come in Miami.

Left-hander Braxton Garrett starts for the home squad. He’s 7-4 with a 3.94 ERA and 1.172 in 25 games (24 starts) this season. The 26-year-old has been pitching well lately to the tune of a 2.57 ERA over his last five starts. Garrett gave up just one and four hits over six innings while striking out eight in a win over the Nats in D.C. back in June.

James McCann is catching tonight and Ryan McKenna is in center field for the start of a three-game series against the Rockies.

Anthony Santander, with three home runs in two nights, is in right field. Adley Rutschman is the designated hitter.

Jordan Westburg is playing second base.

Opponents are batting .163 against Cole Irvin this month in five appearances.

The Orioles need two victories to clinch their first back-to-back .500 or better seasons since 2015-16.

NEW YORK – After a difficult Wednesday night at Yankee Stadium, the Nationals are right back here for their series finale, hoping there’s at least some encouraging news about Stone Garrett and focused on trying to win the rubber game of the series.

Garrett was officially placed on the 10-day injured list with a fractured left fibula, so the Nationals replaced him on the active roster with infielder Jeter Downs, who was recalled from Triple-A Rochester only three days after he was sent down to allow Carter Kieboom to remain here in the big leagues. That does leave them with only three true outfielders (Lane Thomas, Alex Call, Blake Rutherford) but Ildemaro Vargas, Jake Alu, Michael Chavis and even Downs can play out there if needed.

The Nats need to do more at the plate than they’ve done so far this week. Since that four-run outburst in the first inning in Williamsport on Sunday night, they’ve scored a total of three runs, each of those via solo homers. Some more sustained offense would be a big help, especially on a day when the Yankees are throwing a bullpen game, with right-hander Michael King set to pitch first.

Patrick Corbin gets the start for the Nationals, facing another American League team. He’s been notably better in interleague games this season, going 6-3 with a 4.03 ERA. And he’s been great in his last three such starts, going 3-0 with an 0.90 ERA against the Mariners, Rangers and Red Sox. It’ll be fascinating to see if that trend continues today against what had been an awfully weak Yankees lineup before Wednesday night’s nine-run explosion.

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

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

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

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

The Orioles are back home tonight and trying to improve their record to 28-13 in series openers.

Anthony Santander is out of the lineup again with lower-back soreness. Ryan McKenna is in right field.

Gunnar Henderson is batting third. Austin Hays is the cleanup hitter.

James McCann is catching, with Adley Rutschman serving as designated hitter.

Ryan Mountcastle has reached base in 26 consecutive games. He went 11-for-13 against the Blue Jays during a four-game series in Toronto.

NEW YORK – After an eventful day in Williamsport and then an eventful off-day in New York, the Nationals get back to work tonight with the opener of a three-city trip that will take them up and down the East Coast and even across international borders.

It begins tonight at Yankee Stadium, where the home team is in a freefall, having lost eight in a row, falling four games under .500 and 9 1/2 games out of the American League wild card race. Yes, the Nats are closer to a playoff berth (eight games) than the Yankees. Strange times, indeed.

Davey Martinez (whose new two-year contract was officially announced today) has a lineup loaded with eight right-handed bats, including Carter Kieboom, who makes his first appearance in a big league game since 2021. He’s also got both Keibert Ruiz and Riley Adams in the lineup together, something we’re seeing most of the time now when the Nats are facing a lefty like Carlos Rodón.

Josiah Gray, meanwhile, makes his first career start at Yankee Stadium, just a stone’s throw away from his childhood home in New Rochelle. The young right-hander has been teetering a bit in recent outings. He’ll surely be motivated tonight, but the Nationals need quality from him.

WILLIAMSPORT, Pa. – Hello from Muncy Bank Ballpark at Historic Bowman Field, the longtime home of the minor league Williamsport Crosscutters and home tonight of the MLB Little League Classic between the Nationals and Phillies.

For the first time in club history, the Nats are playing in a neutral-site location, selected last year to participate in the sixth edition of the Little League Classic. They are still considered the home team, so they’ll bat last just like the game was being played back in D.C.

It’s already been a long and exciting day, with both teams arriving at the local airport to awaiting kids and media members, then spending a couple hours at the actual Little League World Series just a few miles away from here. Much of tonight’s very small crowd will be comprised of those Little Leaguers, so it should make for a very different environment than any of these big leaguers are used to.

As for the actual game, the Nationals are looking to bounce back from Saturday’s game, which they led 3-0 in the seventh and saw fall apart before their eyes as an overworked bullpen finally crumbled. The good news: All the top relievers should be available to pitch tonight if the situation calls for it.

To get there, they’ll first need a better start out of Trevor Williams, who has struggled big-time of late. The right-hander gave up five runs via three homers and threw 93 pitches in 4 1/3 innings against the Athletics his last time out. Prior to that, he gave up six runs via three homers and threw 103 pitches in 4 2/3 innings against the same Phillies lineup he’ll face tonight.

The Nationals faced Michael Lorenzen nine days ago, and it didn’t exactly go so well for them. Like, they didn’t even record a hit off the Phillies right-hander, who became the first pitcher to ever throw a no-hitter against the Nats since they arrived in D.C.

So wouldn’t you know Lorenzen’s next start would just so happen to come tonight against the same team he no-hit in Philly? Yes, after getting some extra rest, Lorenzen returns tonight and will attempt to do what only Johnny Vander Meer has ever done in major league history. The chances of him doing it again are awfully slim. Still, it would be nice if the Nationals could just get one early hit and not even let the thought of it creep into anyone’s head.

Joan Adon takes the mound for the Nats, and it will be interesting to see how the right-hander handles the situation. He departed his last start with leg cramps, something he also experienced at the end of his dominant start in Cincinnati, and Davey Martinez said they might try an old-school remedy in advance of this outing to combat the issue: pickle juice. We’ll see if it works.

The Nationals have already gone 4-1 on this homestand. They’ve got a chance to add to that today and reach a significant milepost for the season. Their next win will be No. 55, which would match their 2022 total. Yeah, there are still 40 games to go after today. That would be quite the accomplishment by mid-August.

It’s a couple of veteran left-handers who have seen better days on the mound against each other. Patrick Corbin enters with a 4.85 ERA and league-high 162 hits allowed, but he comes off a really weird start in Philadelphia in which he walked a career-high seven batters but allowed only one (unearned) run on one hit over five innings. He’ll need to be more around the strike zone today to have a chance against Boston.

Chris Sale, meanwhile, enters with a 4.52 ERA and only returned last week from a two-month stint on the injured list. The 34-year-old was good in his return, though, holding the Tigers to two runs on one hit while striking out seven in 4 2/3 innings.

SAN DIEGO – Aaron Hicks is out of tonight’s lineup as the Orioles attempt to win their 24^th series.

Hicks didn’t play last night after leaving Monday’s game with back soreness.

Adley Rutschman is serving as the designated hitter. Gunnar Henderson is the cleanup hitter and third baseman. Jordan Westburg is playing second base.

Austin Hays is in left field. Hays homered last night in the ninth inning but is batting .192 since the break.

Ryan Mountcastle has reached base in 22 consecutive games, the longest Orioles streak since Trey Mancini’s 23 from Sept. 5, 2019 to April 2, 2021, and the longest in a single season since Mancini reached in the last 22 games in 2019.

SAN DIEGO – Aaron Hicks is starting in left field and batting eighth tonight after his reinstatement from the injured list earlier today.

Cedric Mullins is in center field and batting sixth. Austin Hays sits against Padres right-hander Yu Darvish.

Adley Rutschman stays in the leadoff spot, followed by shortstop Gunnar Henderson.

Jordan Westburg is playing second base and batting ninth.

Ryan Mountcastle, the designated hitter tonight, is slashing .418/.488/.672 with four home runs and 13 RBIs during his 20-game on-base streak.

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.

SEATTLE – After being held to one run on two hits over six innings by right-hander Luis Castillo last night, the O’s face another tough righty tonight. George Kirby (10-8, 3.32 ERA) will make his 23^rd start for Seattle.

The Mariners hit three homers off Kyle Gibson in last night’s 9-2 win. Seattle (63-52) is now just half a game out of the final wild card spot in the American League.

Adley Rutschman, batting .314 in 13 games atop the batting order, is batting leadoff again tonight. Cedric Mullins, who hit fifth last night, bats second tonight. Jorge Mateo is starting at shortstop and Gunnar Henderson is not starting. 

Kirby ranks ninth in the American League in ERA and first in walks per nine innings (0.9) and first in strikeout-to-walk ratio at 8.86. On June 25 he gave up three runs (two earned) in 6 1/3 versus the Orioles.

Seattle has won eight in a row and 10 of 11 games and is 16-4 in the last 20. The M’s pitching has given up just seven runs the last five games, and 20 in the past eight.

The Orioles will attempt to rebound from last night’s 9-2 loss, their third in the last four games, by sending left-hander Cole Irvin to the mound for his first start since July 7 in Minnesota.

Irvin has made six relief appearances in a row. He’s inserted into a rotation now designed to provide more rest for the younger starters.

Irvin is 0-6 with an 8.42 ERA and 2.065 WHIP in six career games against the Mariners. He’s allowed 24 earned runs and 25 total with 41 hits in 25 2/3 innings.

Cedric Mullins is batting second tonight behind catcher Adley Rutschman. Gunnar Henderson is on the bench.

Ryan Mountcastle is the cleanup hitter, bumping first baseman Ryan O’Hearn to fifth. Mountcastle’s hitting streak ended last night at 12 games, but he’s reached base in 18 straight to set a career high.

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.

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.
