Mikolas is expected to pitch in bulk relief behind opening pitcher PJ Poulin in Sunday's game against the Mariners, Kyle Williams of TheBanner.com reports.
Mikolas will be making his sixth straight appearance as a bulk reliever, this time working behind Poulin after lefty Richard Lovelady served as the Nationals' opener in Mikolas' previous turn through the rotation Monday against the Giants. The veteran right-hander has gone 0-2 with a 4.32 ERA, 1.08 WHIP and 14:3 K:BB in 25 innings over his last five outings.
