The damage against Brandon Young today consisted of two unearned runs over 6 2/3 innings. The Orioles got exactly what they needed, perhaps more than they could have expected, in Game 1 of a doubleheader.

They didn’t look like a team that would get a win, which also was needed. But the Tigers are a nice tonic for them.

Colton Cowser hit a two-out, three-run homer off Kenley Jansen on a two-strike pitch to give the Orioles a dramatic 5-3 win before an announced crowd of 17,616 at Camden Yards. The nightcap begins at 6:05 p.m.

Jansen, trying for the four-out save, walked Jackson Holliday and Leody Taveras with one out in the ninth, and they executed a double steal with Cowser at the plate. He launched a sinker 440 feet to center field and flung his bat toward the dugout. The ball left his bat at 111.5 mph. It was the first walk-off of the season for the Orioles.

Young threw a career-high 105 pitches, the last nine resulting in a walk that forced him out of the game. He allowed five hits and his ERA decreased from 4.25 to 3.47 in seven starts.

Keegan Akin stranded an inherited runner, but he allowed a run in the eighth to pad the margin and increase his ERA to 12.66. He came out with the bases loaded and two outs, and Dietrich Enns retired Zack Short on a fly ball.

Jeremiah Jackson began the bottom of the eighth with a double off Kyle Finnegan and he scored with one out on Taylor Ward’s single. Gunnar Henderson, who homered earlier, walked to add momentum to the rally, but the runners were stranded.

Pete Alonso popped up for the final out and slammed his bat to the ground.

Cowser almost smashed his in half.

The Orioles are 23-29.

Young retired the first eight batters before Short doubled off the left field fence with two outs in the third.

Kevin McGonigle led off the fourth with a single and reached second base on a fielder’s choice and throwing error on Alonso, who let a low popup drop in an attempt at a double play, had the ball skip past him and tried to get the force after a sliding stop. The throw bounced past Jeremiah Jackson, who couldn’t make the scoop. Meanwhile, Young didn’t break for the bag, which removed any chance for the out at first.

Matt Vierling had an RBI single with one out and Colt Keith’s sacrifice fly made it 2-0.

Alonso is playing an exceptional first base this season, far beyond his career defensive metrics. His plus-3 outs above average are tied with Cowser for the team lead. Alonso shook his head after the error, clearly upset with the decision he made and the result.

Young escaped a two-out jam in the sixth after an infield hit and bloop single. The bullpen began to stir with Young at 82 pitches, but he came back out for the seventh and struck out the first two batters before walking Zach McKinstry.

Also, Mustard was ahead in the Hot Dog Race and someone tripped him, a clear case of interference that won’t quiet the conspiracy theories.

The Orioles couldn’t get their offensive footing against Framber Valdez, who carried a one-hit shutout into the sixth.

Adley Rutschman walked in the first and fourth innings. Taveras singled with two outs in the second for the only hit until Henderson belted his 11th homer with one out in the sixth. Henderson deposited a first-pitch curveball onto the flag court to reduce the lead to 2-1.

Alonso flied to the center field fence 396 feet away and at 109.4 mph to end the inning.

Nine of Henderson’s 11 homers have gone to right field and the other two to center. He began today batting .370 with a .593 slugging on the first pitch.

Valdez allowed one run and two hits in six innings and came out after 92 pitches.

*Coby Mayo was a late scratch today with lower-back tightness, leaving the Orioles a player short in the doubleheader.

Mayo became the sixth Oriole to be removed from the lineup before first pitch, joining Tyler O’Neill on April 10, Rutschman on April 11, Blaze Alexander on May 8, Samuel Basallo on May 11 and Dylan Beavers on May 12.

Beavers is on the 10-day injured list with a right oblique strain.

*The Orioles haven’t announced their rotation for the Rays series that begins Monday afternoon at Camden Yards. Tampa Bay is again listing Shane McClanahan, Griffin Jax and Steven Matz.

*Class A Delmarva’s Caden Hunter struck out nine batters in four innings today. He allowed one run and two hits.

Double-A Chesapeake left-hander Luis De León allowed two runs and four hits with six strikeouts in four innings.
