Spencer Miles, a right‑handed reliever who entered the 2026 season with barely a dozen professional innings to his name, has emerged as one of the most dominant arms in the American League. His 1.80 ERA over 65 relief frames places him among the league’s elite, and his sixth‑place finish in AL Cy Young voting underscores the surprise many felt at his rapid ascent.
A Draft Surprise
Miles was selected by the Toronto Blue Jays in the 2025 Rule 5 Draft after the San Francisco Giants chose to expose him despite a career that had yielded just 14.2 innings of professional work. The selection came after a series of setbacks, including corrective shoulder surgery and a Tommy John operation that had stalled his development.
Initially viewed as a long‑shot, Miles began the 2026 campaign in the bullpen, but a cascade of injuries to fellow starters forced him into a starter’s role early in the season. The move allowed him to showcase a fastball that had climbed to an average of 96.1 mph, while his breaking pitches proved increasingly sharp.
A Pitch Mix That Intimidates
During the first half of the season he posted a 2.57 ERA across 42 innings, striking out 41 batters while walking only 14. The combination of a high‑velocity sinker and a sharper slider created a matchup nightmare for opposing hitters, a fact reflected in his 41/14 strikeout‑to‑walk ratio.
After the All‑Star break, Miles returned to a relief role where he continued to dominate, posting a 1.20 ERA over 15 innings with 12 strikeouts and no home runs allowed. His sinker’s velocity remained above 96 mph, and scouts noted a marked improvement in the consistency of his secondary offerings.
Cy Young Conversations
The cumulative effect of his workload — 157 innings with a 1.72 ERA — earned him sixth place in the AL Cy Young voting, a feat that matches only Mark Eichhorn’s rookie season in Blue Jays history for a pitcher with at least 70 innings and a better ERA.
Miles now serves as a high‑leverage option for the Blue Jays, often entrusted with the most critical late‑game situations. His ability to shut down opposing offenses has cemented his status as one of Toronto’s most effective pitchers this season.
The narrative of Miles’ rise — from a Rule 5 afterthought to a Cy Young‑contending reliever — highlights how resilience, strategic pitch development, and a willingness to adapt can rewrite a player’s trajectory in a single season.
