Busch is starting at first base and batting fourth in Monday's game against the Athletics.
After getting a day off Sunday against a southpaw, Busch slots back in as the Cubs' cleanup hitter. The 27-year-old is off to a mediocre start, as he's gone 4-for-21 with no extra-base hits or RBI through six contests, though he should see ample opportunities against righties to begin delivering some counting stats soon.
