Rockies Promote Sean Sullivan, Worth an Add Ahead of Debut?
Colorado Rockies pitching prospect Sean Sullivan is set to make his MLB debut on Friday night as his team's starter against the Athletics, per Kevin Henry of The Denver Gazette. The 23-year-old has largely struggled with Triple-A Albuquerque so far this season, recording a 5-3 record with a 5.60 ERA, 1.55 ERA, and 50 strikeouts across 54 2/3 innings (11 starts). However, he's been victimized by an abnormally high 14.7% HR/fly ball rate while pitching in the extremely hitter-friendly Pacific Coast League. Sullivan was much more productive across 97 1/3 innings (18 starts) with Double-A Hartford in 2025, logging a 3.14 ERA and 1.09 WHIP with a 24.2% strikeout rate. Sullivan will pitch in a hitter-friendly environment in Colorado, which lowers his fantasy appeal. Still, the young left-hander could be worth adding off the waiver wire in deeper league formats.
