CLEVELAND – The Orioles didn’t wait until Thursdays’ roster expansion to select infielder Gunnar Henderson’s contract from Triple-A Norfolk.

They did it early this afternoon, bringing up Henderson and optioning infielder Tyler Nevin to Norfolk.

Pitcher Denyi Reyes was designated for assignment to create room on the 40-man roster.

Henderson, who’s wearing No. 2, could be in tonight’s lineup against Guardians right-hander Triston McKenzie. We’ll find out later.

The first appearance will allow Henderson, 21, to become the youngest Oriole to make his major league debut since infielder Manny Machado in 2012. Machado was a first-round shortstop who switched to third base. Henderson is a second-round shortstop in 2019 who’s played all four infield positions in the minors, gaining experience on the right side this month.

ST. PETERSBURG, Fla. – The Orioles clubhouse was livelier this afternoon, the televisions tuned to baseball and golf, and players joking and interacting with each other.

Last night’s 5-4 loss, which ended a 10-game winning streak, created silence and left the Orioles visibly frustrated.

“We’ve been playing so well,” said manager Brandon Hyde. “Just disappointing that we lose a close game like that. We feel like it’s a game we should have won.”

Stranding eight runners in the first six innings hinted at disaster.

“We had our opportunities early in the game to add on a lead.” Hyde said. “When you let teams like this hang on - we’ve seen it in the past with these guys - it’s very, very difficult.

The Orioles are removing pitcher Dean Kremer from his rehab assignment at Triple-A Norfolk and installing him as today’s starter against the Guardians in the last game of the series.

Kremer has tossed nine scoreless innings in three minor league starts, with two hits, two walks and 18 strikeouts.

This is Kremer’s first appearance with the Orioles since he started the first game of a Sept. 11, 2021 doubleheader against the Blue Jays and allowed five runs and seven hits in four innings. Toronto hit three home runs.

The final touches on a season that Kremer wants to forget.

He went 0-7 with a 7.55 ERA and 1.640 WHIP in 13 starts, competed for a rotation spot in spring training, and strained his oblique while warming in the bullpen during the third game at Tropicana Field. Kremer was supposed to enter in relief, but walked to the dugout with the injury.

The Orioles swapped out pitchers again today, recalling Denyi Reyes from Triple-A Norfolk and optioning left-hander Zac Lowther.

Lowther threw 100 pitches last night in 5 1/3 innings. Reyes was the 27^th man for Saturday’s doubleheader in Boston, allowing one run in 3 2/3 innings in Game 2, and remained eligible to be recalled in fewer than 10 days.

Lowther was the first Orioles reliever last night to throw at least 100 pitches since Gabriel Ynoa on May 5, 2017.

Adley Rutschman is on the bench tonight as the Orioles continue their series against the Mariners. He’s 7-for-39 in 10 games.

Trey Mancini is playing first base and Anthony Santander is the right fielder and cleanup hitter.

BOSTON – Denyi Reyes went from a modest signing back in November, a minor league contract that barely drew notice, to his first major league start tonight. Against the team that let him go as a free agent.

These stories can swerve in any direction. A tale of redemption or bitter disappointment.

Reyes had some fun with it, neither vindictive nor victorious.

Jorge López had his own family story and it produced a beautiful chapter, his 9-year-old son Mikael able to watch him pitch, to record a four-out save. 

The night couldn't have gone any better.

BOSTON – The Orioles brought a small taxi squad to Boston for the five-game series, and it could provide a clue to the identity of Saturday’s starter.

Right-handers Denyi Reyes and Cody Sedlock reported to Fenway Park, along with catcher Cody Roberts.

Reyes is on the 40-man roster and could start one of the doubleheader games. Sedlock is a non-roster pitcher who became a candidate simply by making the trip.

Sedlock was supposed to start Thursday at Triple-A Norfolk until a rainout the previous day pushed DL Hall into a doubleheader with Zac Lowther. Grayson Rodriguez is pitching tonight for the Tides.

The Orioles selected Sedlock with the 27^th overall pick in the 2016 draft out of the University of Illinois, and he’s waiting to make his major league debut. He has a 5.83 ERA and 1.466 WHIP in eight games (four starts) this season, with 35 strikeouts in 29 1/3 innings.

After a bullpen game on Thursday, pitching was not the issue in Friday night's 4-2 loss to the Tigers. 

Brandon Hyde needed starting pitcher Jordan Lyles to eat some innings tonight against the Tigers. In Thursday’s series-deciding victory over the Cardinals, Hyde turned to six relievers to get the job done; Bryan Baker, Keegan Akin, Dillon Tate, Cionel Pérez, Joey Krehbiel and Félix Bautista. 

A long outing from Lyles would give those bullpen arms a much needed rest. The stars were all aligning for that scenario to play out, and for the most part, it did. None of those names appeared in tonight's game. 

"It was great to be able to rest some guys in the back of the 'pen today, coming off a day where we threw a lot of guys for multiple innings," said manager Brandon Hyde. 

In the first, Javier Báez grounded into a double play, approximately the 1,000th double play that the Orioles have turned this year. OK, fine, it was the 41st. That’s still a lot of double plays. Most in the American League, in fact. 

ST. LOUIS - The Orioles made multiple adjustments to their health-challenged roster this morning, with Rylan Bannon recalled from Triple-A Norfolk and given his first start in the series finale against the Cardinals.

Bannon is playing third base in his major league debut. He joined the taxi squad yesterday.

Left-hander Paul Fry was optioned to Norfolk.

Ryan Mountcastle and Ramón Urías are day-to-day with a sore wrist and abdomen, respectively. Urías said this morning that he felt better, but “not great, great.”

“Urías and Mountcastle both trending better, still not available today,” said manager Brandon Hyde. “Hopefully, they’ll be available off the bench, but not sure. They’re still getting treatment right now. We felt like we needed an extra body.”

ST. LOUIS – Bryan Baker makes his first career start in the majors as the Orioles commit to a bullpen game to close out their series against the Cardinals.

Baker has made 12 relief appearances, including 11 this season with the Orioles. He’s allowed six runs and 11 hits with 11 strikeouts in 10 innings in 2022.

Baker started 13 times in 174 minor league games.

Manager Brandon Hyde hasn’t used Baker for more than 1 2/3 innings or 24 pitches. Left-hander Keegan Akin could provide bulk innings behind him.

Baker’s last appearance was May 5.

The Orioles close out their series in Oakland this afternoon with Tyler Wells on the mound and a chance to gain a split after last night’s 1-0 win – the team’s third shutout of the season.

Wells is making his third start after tossing four scoreless innings against the Yankees. He’s been stretched out to 64 pitches.

The rotation has registered a 1.13 ERA since April 11, the lowest in the majors, with five earned runs in 39 2/3 innings.

The Orioles and Giants have allowed three home runs, fewest in the majors. The Orioles and Mets are the only staffs with three shutouts.

On the offensive side, the Orioles’ four home runs and 24 runs scored are the fewest in baseball. The .585 OPS is the lowest in the American League and third-lowest in the majors.

The lockout that occurred seconds after the expiration of the collective bargaining agreement could produce the largest gap between an Orioles free agent agreement and actual signing in franchise history. Pitcher Jordan Lyles accepted the terms of his one-year, $7 million deal, which also contained an $11 million club option for 2023 and $1 million buyout. But the ink hasn't dried on the contract because a pen never touched paper. The transaction is pending a physical that can't be done until...
