The Red Sox recalled Gasper from Triple-A Worcester on Saturday, Jen McCaffrey of The Athletic reports.
Gasper will serve as the roster replacement for Rafael Devers (shoulder), who landed on the 10-day injured list. The former has spent the majority of the season in the minors, slashing an impressive .328/.439/.531 with 12 homers and 58 RBI across 380 plate appearances between Double-A and Triple-A, though he doesn't project to see much playing time while in Boston.
