McKinstry’s move to the injured list is retroactive to April 22.
If he logs time, Peters’ current MLB stint will mark his big-league debut.
Over the course of his four-year minor league career, Peters was named Player of the Week six times across three levels. He garnered multiple All-Star nods during that stretch, and he was named the Cal League Player of the Year in 2017, when he slashed .276/.372/.514 with 27 homers, 29 doubles and 82 RBI for High-A Rancho. In 2018, he led Double-A Tulsa with 29 bombs in 132 games.
Splitting the 2019 season with Tulsa and Triple-A OKC, Peters appeared in 68 games for the Drillers, hitting .241 with 10 doubles, 11 homers and 42 RBI while batting .260 (54-for-208) with 10 doubles, 12 homers and 39 RBI in 57 games for Oklahoma City.
Last year, he was a member of the team’s 60-man player pool.
The former Glendora High School alum made 25 appearances during 2021 Cactus League play in spring training, batting .243 (9-for-37) with two homers and five RBI.
The 6-foot-6, 225-pounder is probably best known for his power, but he has deceptive speed and athleticism for his size. Defensively, he can handle all three outfield spots, and his arm strength is one of his best assets.
MLB Pipeline currently ranks the 25-year-old Peters as the Dodgers’ 21st best prospect.
McKinstry, 26, will make his first trip to the injured list after appearing in 17 games for the Dodgers this season. In 17 contests, he slashed .296/.328/.556 with three homers and 14 RBI. He recorded his first career homer on April 3 at Coors Field—an inside-the-park variety—becoming the first Dodger to accomplish the feat since Duke Snider on May 2, 1948.
In five minor league seasons in the Dodgers organization, McKinstry has hit a combined .270 (331-for-1226) with 30 homers and 149 RBI across five different levels.
Peters will wear uniform No. 70.
