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.
