Scouting Report
Updated May 20, 2026
Spencer Miles, a 25-year-old Rule 5 pick for the Toronto Blue Jays, has been given an expanded role in the team's rotation as a bulk reliever/opener while starters Shane Bieber and Max Scherzer recover from injuries. Miles recently threw a season-high 3.2 innings and 56 pitches against the Detroit Tigers on Saturday, May 16, 2026. Manager John Schneider emphasized the importance of consistency in Miles' role, stating the team wants to avoid moving him back and forth between positions.
