Prospect Sean Sullivan Continues Spring Rotation Bid

Top Rockies prospect Sean Sullivan is set to start against the Diamondbacks. The lefty has impressed this spring with his deception and breaking pitches, posting seven strikeouts and three walks over 6 2/3 innings across four outings. While his four-seam fastball velocity remains a concern, Sullivan is competing for a spot in the big-league rotation. Although unlikely to break camp on the active roster, he continues to receive opportunities to showcase his skills.
