William Stanley "Bill" Mazeroski, the legendary Pittsburgh Pirates second baseman whose dramatic walk-off home run clinched the 1960 World Series, passed away on February 20, 2026, at the age of 89. A beloved figure in baseball, Mazeroski was celebrated for his exceptional defensive skills and his singular, iconic moment that remains etched in sports history. He spent his entire 17-year Major League Baseball career with the Pirates, leaving an indelible mark on the franchise and the game.

Known affectionately as "Maz," he was widely regarded as one of the greatest defensive second basemen of all time. Mazeroski earned eight Gold Glove Awards during his career, a testament to his unparalleled fielding prowess. He consistently led the National League in double plays and assists, setting numerous records for his position. His ability to turn a double play with remarkable fluidity and precision made him a cornerstone of the Pirates' infield for nearly two decades.

While his glove work defined much of his career, it was his bat that delivered one of baseball's most unforgettable moments. On October 13, 1960, in Game 7 of the World Series against the heavily favored New York Yankees, Mazeroski hit a ninth-inning, walk-off home run, securing the championship for Pittsburgh. This historic blast remains the only Game 7 walk-off home run in World Series history, a moment of pure exhilaration that brought a championship to the city and cemented his place in baseball lore.

Beyond the 1960 triumph, Mazeroski was also a key member of the 1971 Pirates team that won another World Series title. His consistent play and leadership earned him seven All-Star selections throughout his career. In recognition of his enduring contributions to the sport, he was inducted into the National Baseball Hall of Fame in 2001, primarily for his defensive excellence. Mazeroski's legacy as a humble, gracious, and fiercely dedicated Pirate will be deeply missed by fans and the baseball community alike.
