Who will be the hero of the 2026 MLB playoffs? ESPN is tracking the cumulative win probability added (WPA) figures for every player in the postseason to find out. The tracker adds a twist: the deeper the playoffs go, the more weight each game carries. Division series count double the wild-card round, the championship series doubles again, and the World Series doubles once more. Players who shine early can still climb the leaderboard, but the path is harder. Coming through when championship leverage is highest is what makes someone an October hero.
Wednesday's standout was not only Jose Ramirez, who drew most of the headlines. The bigger impact came from Jo Adell, whose bases-clearing triple off Chicago's Hagen Smith gave the Guardians an early buffer. That hit proved decisive in Cleveland's season-saving win over the White Sox.
The methodology tracks each player's WPA on a per-game basis, with each playoff round weighted double the previous one. The totals are then converted to an AXE-style index in which 100 represents the average for all postseason players. The "Change" column shows how each active player's AXE number moved from the previous day, and readers can sort by that column to find the day's heroes and goats.
The tracker offers a running view of who is delivering in the moments that matter most. As the 2026 playoffs advance, the index will show which players are building lasting October reputations.
