Mikolas is expected to be deployed in bulk relief behind opener Richard Lovelady in Sunday's game against the Orioles, Mark Zuckerman of NatsJournal.com reports.
Mikolas started his prior three appearances, but the Nationals are opting to bring him out of the bullpen for the fourth time this season Sunday. Mikolas accrued a 4.09 ERA, 1.27 WHIP and 5:3 K:BB in 11 innings over his prior three bulk relief outings.
