Ryan Sloan a Budding Arm in Seattle System
Seattle Mariners right-handed pitching prospect Ryan Sloan is a name to closely monitor in dynasty formats ahead of the 2026 campaign. Sloan joined the Mariners in the second round (55th overall) in the 2024 MLB Draft out of York Community HS. After just one professional campaign, Sloan is now ranked as the sport's No. 44 prospect and Seattle's No. 4 prospect on MLB.com entering spring training. Additionally, Sloan is viewed as one of the top right-handed pitching prospects in baseball, ranking sixth at his position. He made his professional debut in 2025 with Low-A Modesto, where he spent most of his campaign. Through 70 2/3 innings, the right-hander posted a 3.44 ERA, 1.15 WHIP, with a 77:15 K:BB. He was then given a short 11 1/3-inning stint at High-A, where he allowed seven earned runs. While he is likely ticketed for High-A to open the 2026 season, managers should continue to closely monitor his progression as he could develop into one of the sport's top pitching prospects.
