Gamboa (elbow) recorded two outs via strikeout and allowed one earned run on three hits in his relief appearance Friday in the Red Sox's 2-0 win over the Rays.
Gamboa made just his second appearance of the Grapefruit League and his first since Feb. 28 after he was briefly shut down due to a left elbow issue. The injury prevented Gamboa from staking a claim to a spot in the Opening Day bullpen, as the Red Sox reassigned him to minor-league camp Saturday.
