The Boston Red Sox added first baseman/outfielder Garrett Cooper to the major league roster and designated utility player Pablo Reyes for assignment on Monday.
The Red Sox acquired Cooper from the Chicago Cubs on Saturday for cash considerations.
Cooper, 33, was designated for assignment by the Cubs last week after hitting .270 with a home run and six RBIs in 12 games. His playing time was limited with the emergence of Michael Busch.
Boston has playing time available at first base with Triston Casas (ribs) currently on the injured list.
In eight seasons with three different clubs, Cooper is a .268 hitter with 57 home runs and 228 RBIs in 493 games. He combined to hit 17 home runs with 61 RBIs in 123 games for the San Diego Padres and Miami Marlins last season.
He replaces Reyes on the 26-man active roster. Reyes is batting .183 with five RBIs and 19 strikeouts in 21 games this season.
Reyes, 30, is a career .248 hitter with eight homers and 54 RBIs in 232 games with the Pittsburgh Pirates (2018-19), Milwaukee Brewers (2021-22) and Red Sox. He missed the 2020 season after being suspended for violating the league’s policy on performance-enhancing drugs.
