Carasiti (elbow) signed a minor-league contract with the Giants on Thursday.
Carasiti joined the Red Sox on a minor-league deal last year but spent the entire season on the injured list after he underwent Tommy John surgery in March of 2020. It's not yet clear when he'll be ready to pitch, but it wouldn't be surprising to see him invited to major-league spring training in 2022 if he's healthy by then.
