Cole Irvin’s return to Oakland went well for the left-hander, but it took an extra inning for it to be good for his team.

While the former Athletics starter pitched five solid innings, his offense needed a 10th frame to decide Saturday night’s contest. After failing to score for the previous six innings, Baltimore’s bats broke the game open in the final one, plating five runs en route to a 7-2 victory.

Six Orioles batters either reached base or drove in a run in the 10th. Adley Rutschman led off with a walk, and Ryan Mountcastle followed with a go-ahead RBI single to score automatic runner Adam Frazier. After Gunnar Henderson was hit by a pitch, Jordan Westburg drove in Rutschman with a sacrifice fly and Austin Hays brought home Mountcastle with a fielder’s choice ground ball. James McCann then provided two pivotal insurance runs with a two-run single to give the Orioles’ bullpen a large cushion.

Reliever Jacob Webb hit and walked the first two batters of the 10th, but the club’s newest bullpen addition struck out the next three batters for a scoreless inning. Aside from Shintaro Fujinami, another former Athletics pitcher whom the Orioles traded for, the Orioles’ bullpen was excellent for the second straight night.

The relief corps pitched four shutout frames in Friday night’s 9-4 win and allowed just one run in six innings Saturday. Fujinami allowed a solo homer in the sixth that tied the game, but Yennier Cano, Cionel Pérez, Félix Bautista (8-2) and Webb followed with scoreless outings.

Hays homered in the fourth to tie the game at one, and McCann remained hot with a solo homer two batters later that gave the Orioles a brief 2-1 lead.

Baltimore is 76-47 and 2 1/2 games up on the Tampa Bay Rays atop the American League standings.
