Busch isn't in the starting lineup for Sunday's matchup versus Boston.
With the Red Sox sending southpaw Garrett Crochet to the mound, Busch will begin the game on the bench. It's the second straight time he's been held out against a left-hander, and the 27-year-old slugger has posted a mediocre .613 OPS against southpaws this season. Justin Turner will start at first base for the Cubs on Sunday.
