Grove was called up from Double-A Tulsa ahead of his start Sunday against the Phillies, Jack Harris of the Los Angeles Times reports.
The 25-year-old will make his big-league debut Sunday in a spot start, filling the gap in Los Angeles' rotation following the placement of Clayton Kershaw (pelvis) on the injured list. Grove struggled at the Double-A level with a 7.86 ERA last year, but he's pitched well so far in 2022 and has a 2.76 ERA, 0.99 WHIP and 22:5 K:BB across 16.1 innings.
