Devers’ arrival came two days after San Francisco acquired the three-time All-Star in a blockbuster deal with the Red Sox, who received left-hander Kyle Harrison, right-hander Jordan Hicks, 2024 first-round Draft pick James Tibbs III and pitching prospect Jose Bello in return.

"A little bit of DH and a little bit of first base,” Giants manager Bob Melvin said about Devers's role with the team.

Gabriel Arias hit a go-ahead homer in the sixth inning and doubled in the ninth on a night when San Francisco celebrated new slugger Rafael Devers at every chance, and the Cleveland Guardians spoiled the fun by beating the Giants 3-2.
