Marcelo Mayer will join the Boston Red Sox Saturday. The team’s top shortstop prospect was seen receiving congratulations in the Worcester Red Sox clubhouse ahead of the team’s first game of a doubleheader.

Ryan O’Hearn hit a two-out, tiebreaking single in the eighth and reliever Seranthony Domínguez got Rafael Devers to pop out to end the bottom of the inning, helping the Baltimore Orioles to beat the Boston Red Sox 2-1 on Saturday night and avoid a sweep of the split doubleheader.

Trevor Rogers delivered a strong start in his season debut and the Orioles’ offense did just enough to salvage a doubleheader split.

On Wednesday, Hendriks was saddled with the loss against the Mets after he allowed three earned runs in two-thirds of an inning. Hendriks, who beat non-Hodgkin’s lymphoma in 2023, received “horrible and cruel” threats after the game that he said were also targeted at his wife.

Marcelo Mayer, Boston’s No. 2 overall prospect, was promoted to the Red Sox and needed to get a ride to Fenway Park to start against the Baltimore Orioles on Saturday.

Seranthony Domínguez and Gregory Soto struggled mightily and the Orioles allowed 13 runs in the 8th inning to open a doubleheader in Boston.

Lefty Cooper Criswell has been called up to be the 27th man on the Red Sox roster for Friday’s doubleheader against the Baltimore Orioles. The Red Sox won Game 1, 19-5. First pitch of Game 2 is scheduled for 7:10 p.m.
