Ryan Sloan Fantasy Stats

Seattle Mariners pitching prospect Ryan Sloan will begin the year at Double-A Arkansas. The Mariners' third-ranked prospect spent most of 2025 at Single-A, where he pitched to a 3.44 ERA, 1.15 WHIP, and a 21.8 percent K-BB%, which earned him three starts at High-A late in the season before an eye procedure ended his campaign somewhat prematurely. The 6-foot-5 hurler is now fully recovered and has looked good this spring by all accounts, although he logged just one inning in the Cactus League. The former second-rounder has a fastball that sits in the upper 90s along with two strong secondary offerings: a changeup and slider. There is projectability in his large frame, and he could make quick work of Double-A, likely making it to Triple-A by the end of the year. Although he should move fast through the organization, he's still just 20 years old, so a 2027 debut is more likely. The right-hander has the makings of a frontline starter and should be stashed away in dynasty leagues.
