Oviedo had his contract selected by the Cardinals and will start Game 2 of Wednesday's doubleheader against the Cubs.
The 22-year-old will likely pitch as long as possible with the Cardinals playing their third doubleheader in the past five days. Oviedo spent most of the 2019 campaign at Double-A Springfield and had a 5.65 ERA, 1.63 WHIP and 128:64 K:BB over 113 innings.
