Scouting Report: Ryan Sloan
Seattle Mariners | P
Overall
Summary
Ryan Sloan is a 20-year-old right-handed prospect ranked No. 25 on FanSided's top 100 list currently pitching at Double-A for the Seattle Mariners. He has struggled early in the 2026 season with a 7.13 ERA over five starts and 17.2 innings, allowing 22 hits and 9 walks. However, he has demonstrated strong strikeout stuff with 20 strikeouts in that span. Command issues are the primary concern limiting his development. At just 20 years old, his path to MLB debut in 2026 appears unlikely given the Mariners' strong existing rotation and the superior performance of fellow prospect Kade Anderson at the same level.
Strengths
- Elite strikeout stuff with 20 K's in 17.2 IP
- Young age (20 years old) with significant upside
