The Red Sox optioned Gamboa to Triple-A Worcester on Saturday.
Gamboa was up with the Red Sox for just one day, as he served as the club's 27th man in Friday's doubleheader versus the Rays. He mopped up in the Red Sox's 10-0 win in the first game of the day, striking out a batter and allowing two hits and no walks over three scoreless innings en route to earning his first MLB save.
