Athletics: C Austin Allen, called up Tuesday to replace C Aramís García since he has a stomach bug, gave regular Sean Murphy a much-needed break from behind the plate so he could be designated hitter. Allen arrived too late for Tuesday's game because of a delayed flight. ... OF Chad Pinder (sprained left knee) continues all his on-field baseball work and is nearing a rehab assignment, perhaps by this weekend. “He's doing everything. Probably goes out on rehab toward the end of our homestand," manager Bob Melvin said.

Ramón Laureano and Matt Chapman homered for Oakland, and Sean Murphy had two hits and two RBIs.

Laureano went deep in the first after Chris Bassitt fell behind 2-0 in the top half — but the right-hander bounced back to pitch a solid outing.

Hernández and Randal Grichuk hit RBI singles in the first inning before Laureano connected for the fourth time in five games. He had a single and double in his following two at-bats, collecting three of the six hits allowed by Robbie Ray in six innings.

Grichuk added another run-scoring single in the decisive five-run eighth.

Bassitt struck out seven over seven innings. He allowed two runs for the fifth straight start.

Ray, who was looking to win back-to-back starts for the first time in 2021, struck out nine and walked none. Jordan Romano (3-1) followed with a perfect seventh for the win.

TRAINER’S ROOM

Blue Jays: OF George Springer went on the 10-day injured list with a strained right quadriceps muscle. He had an MRI exam on his troublesome leg earlier, a change of plans from a day earlier but the decision came after consultation with Springer and the medical staff. The injury forced Springer out Sunday. “The main reason we did it, we just didn't see him improving fast enough so we decided to get some imaging done to determine the next steps,” manager Charlie Montoyo said. OF Jonathan Davis was recalled to replace Springer.

UP NEXT

Ryu (1-0, 2.60 ERA) is set to return from a strained right glute muscle to pitch Thursday. "There's no more hurdles. He's good to go for tomorrow," Montoyo said. Oakland sends RHP Mike Fiers (0-1, 4.50) to the mound for his second start of the season needing seven strikeouts for 1,000 in his career.
