William Stanley Mazeroski (born September 5, 1936), nicknamed "Maz" and "the Glove", is an American former second baseman in Major League Baseball (MLB) who played his entire career for the Pittsburgh Pirates from 1956 to 1972. A seven-time All-Star known during his career primarily for his spectacular defensive play, he has come to be better known for perhaps the most memorable home run in baseball history, a dramatic ninth-inning drive in Game 7 of the 1960 World Series that beat the favored New York Yankees. It was the first time that the major league season ended with a home run, and remains the only walk-off home run to clinch a World Series championship in Game 7. ESPN ranked the World Series winner at the top of its list of the 100 Greatest Home Runs of All Time, while Sports Illustrated had it eighth in its compilation of the 100 Greatest Moments in Sports History. Mazeroski received the Babe Ruth Award for his play in the Series, during which he batted .320.
An eight-time Gold Glove Award winner, Mazeroski was particularly noted for his ability to make the pivot in turning double plays. His 1,706 career double plays remain a major league record for a second baseman, and were the most by any non-first baseman in history until shortstop Omar Vizquel passed him in 2009. Mazeroski led the National League (NL) in double plays eight consecutive years, and recorded over 100 double plays eleven times, both also major league records. His 161 double plays in 1966 remain the major league record for second basemen; when he retired, he held the top three marks in NL history. He led the major leagues in assists a record nine times, and led the NL in putouts five times and in fielding percentage three times. Mazeroski set NL records for career games (2,094), putouts (4,974), assists (6,685) and total chances (11,863) by a second baseman, all of which were later broken by Joe Morgan; his career fielding percentage of .983 ranked second in NL history when he retired, less than a quarter of a point behind Red Schoendienst.
Mazeroski also provided contributions on offense which were not typical for his position; his 138 career home runs and 853 runs batted in (RBI) were the most by any second baseman during the period between 1944 and 1974, with his home run total putting him behind only Rogers Hornsby among NL second basemen when his career ended. His home run production was particularly impressive due to the Pirates playing in cavernous Forbes Field, where the distant reaches in left and center field made it typically the league's most difficult home run stadium until the mid-1960s; Mazeroski hit more than twice as many homers on the road (93) than at home (45) in his career. He closed out his career by helping the Pirates to three consecutive division titles; he and Roberto Clemente were the only members of the 1960 champions who were on the team when they picked up another title in 1971, beating the favored Baltimore Orioles in seven games. Mazeroski later became a coach for the Pirates and the Seattle Mariners. The Pirates organization retired his uniform number in 1987; he is now the only living person so honored. Mazeroski was inducted into the National Baseball Hall of Fame in 2001.
