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.

The Rafael Devers era is here. The Giants’ new star slugger was officially introduced during a press conference at Oracle Park prior to Tuesday night’s series opener against the Guardians.

The Giants lost 3-2 to the Cleveland Guardians despite two hits from Rafael Devers in his debut after Sunday’s trade from Boston.
