Multiple speed threats remain active across ongoing 2026 postseason series, with Jazz Chisholm Jr., Michael Harris II, Jackson Chourio, Fernando Tatis Jr., and similar regulars from the regular-season stolen-base leaderboard still in contention. Short sample sizes in best-of-five and best-of-seven formats allow any player reaching extra innings or advancing rounds to surge with just a handful of successful steals, while team matchups, rest days, and bullpen usage influence opportunities. The wisdom of crowds reflected in current pricing captures this uncertainty, as no single contender has separated on volume or efficiency amid the compressed schedule and variable playing time.
