Several contenders bring elite speed from the regular season, including José Caballero, Jorge Mateo, Michael Harris II, and Brayan Rocchio, while others like Jackson Chourio, José Ramírez, and Ronald Acuña Jr. add matchup-specific threats through recent form and team lineups. Postseason factors such as expanded rosters, aggressive managerial decisions on steals, and varying series lengths keep the outcome fluid, with no single player holding a dominant edge in historical or current usage patterns.
