Colorado Rockies left-handed pitching prospect Sean Sullivan tossed seven innings of one-run ball en route to picking up the victory over Double-A Portland on Tuesday evening. In this outing, Sullivan allowed just four hits and no walks. He struck out seven. This was Sullivan's second-straight contest tallying at least seven punchouts. Since allowing four runs on June 19, Sullivan has logged 17 innings (three starts) to the tune of a 3.18 ERA with a 1.06 WHIP. The 22-year-old has logged 56 2/3 innings with Double-A Hartford this season and posted a strong 3.06 ERA with an impressive 0.94 WHIP. He has shown elite control, allowing just 10 walks. Given his steady production with Double-A, the No. 8-ranked prospect in the system should be in the mix to join Triple-A later this summer.

Colorado Rockies left-handed pitching prospect Sean Sullivan logged five shutout innings during his Double-A season debut on Wednesday evening. Sullivan was sidelined during the start of the season after recovering from hip surgery. He made one start in the Arizona Complex League and with Low-A before getting the call to return to Double-A. On Wednesday, Sullivan allowed just two hits and no walks against Binghamton. He struck out three batters. This was a strong season debut for Sullivan. Last season, the southpaw logged 32 innings with Double-A Hartford and held a strong 1.97 ERA with a 1.09 WHIP. If he continues to find success, he should be in the mix to make his Triple-A debut early in the 2025 season.
