Mikolas won't start as scheduled Tuesday against the Reds since the game was postponed due to inclement weather, John Denton of MLB.com reports.
The game will be made up via a doubleheader Wednesday, with Mikolas likely to start one of those games. The veteran right-hander delivered six scoreless frames in his previous start but has a 5.70 ERA, 1.52 WHIP and 13:9 K:BB over 23.2 innings this season.
