Zerpa was recalled from Double-A Northwest Arkansas and will start Thursday against the Blue Jays.
Zerpa picked up his first big-league win Monday after firing two scoreless innings out of the bullpen for Kansas City, and he'll now briefly join the big-league rotation with the team missing a slew of players due to their vaccination statuses. The left-hander has started 13 games at Double-A this year and has a 4.36 ERA, 1.42 WHIP and 69:21 K:BB across 64 innings. Given he's only on two days rest since Monday's appearance, Zerpa shouldn't be expected to pitch deep into Thursday's contest.
