Miley (shoulder) was activated ahead of his scheduled start Tuesday against the Reds, Meghan Montemurro of the Chicago Tribune reports.
The veteran southpaw will be taking on a Reds lineup composed solely of right-handed hitters. Miley had a 2.84 ERA, 1.21 WHIP and 12:8 K:BB in 19 innings over four starts earlier this season before suffering the shoulder injury.
