Gamboa

Gamboa pitched one scoreless inning in his first stint with Boston last month. He had a 3.66 ERA and a 30/8 K/BB in 32 innings while mostly starting for Worcester.

Gamboa tossed a scoreless inning during his lone relief appearance for the Red Sox after being called up earlier this week. He heads back to the minors to make room for veteran starter Sonny Gray to return from the injured list.

Gamboa gets a shot with Boston as a middle reliever after posting a 6.23 ERA and 15/5 K/BB ratio across 13 innings in three starts for Triple-A Worcester this season. The well-traveled 29-year-old lefty will likely pitch in mop-up duty for the Red Sox. He’ll be making his big-league debut when he gets into a game.

Capra was in Red Sox camp as a non-roster invitee and failed to land a spot on the club’s season-opening roster in a bench role. Delay is merely emergency catching depth while Guerrero and Keller could be up as stopgap relief options at some point later this year.

He’ll make $925,000 if he’s in the majors. Gamboa, 28, was the Dodgers’ ninth-round pick in 2019 and pitched in their farm system until last May, when he made his way to Korea. He wound up 7-8 with a 3.58 ERA and a 117/49 K/BB in 108 innings over 19 starts with Lotte. He’s always been able to generate groundballs, and he could prove to be of some use in middle relief.
