4. Madison Bumgarner – San Francisco Giants (2014, Game 7 Relief)
While Don Larsen’s was the best starter performance, Madison Bumgarner’s legendary relief outing in Game 7 of the 2014 World Series against the Kansas City Royals is arguably the most dominant clutch performance. Having already started and dominated Games 1 and 5, Bumgarner entered Game 7 in the fifth inning with the Giants clinging to a one-run lead. He proceeded to throw five scoreless innings, allowing only two hits and striking out four. Effectively delivering a complete game of his own, he single-handedly shut down the Royals and secured the championship. This incredible, high-leverage endurance display, coming after 21 innings pitched in the Series, defined a new standard for relief pitching dominance.
