- Sean Sullivan, a 23-year-old left-handed pitcher, was invited to the Rockies' big league camp this year and could make his MLB debut in 2026.
- Despite some injury setbacks, Sullivan has been dominant in the minors, posting impressive numbers at the High-A and Double-A levels.
- Sullivan relies on a low-velocity but effective fastball, along with a slider and changeup, to keep hitters off balance and rack up strikeouts.
- The Rockies are excited about Sullivan's potential and will likely bring him along slowly, but he could be in line for a spot in their big league rotation in the near future.
