Senzatela (back) will be activated from the 15-day injured list to start Game 1 of Wednesday's doubleheader against the Marlins.
The right-hander landed on the shelf May 17 with a lower-back strain, but he'll rejoin Colorado's starting rotation after spending the 15-day minimum on the IL. Through seven starts this season, Senzatela has a 4.55 ERA, 1.89 WHIP and 11:8 K:BB across 29.2 innings.
