Gasper went 1-for-5 with a solo home run and an RBI groundout during Boston's 11-1 win over Arizona on Monday.
The Red Sox needed another bat in the lineup after Masataka Yoshida (hamstring) was placed on the 10-day injured list Monday and Jahmai Jones (undisclosed) was a late scratch from the lineup. Gasper got the call from Triple-A Worcester, and he contributed immediately with a solo long ball in the seventh inning, his first in the majors this season and third of his big-league career. He could see additional reps at DH if Jones' absence extends beyond Monday's series opener.
