Moose Skowron, a five-time World Series champion and one of only two players to hit three home runs in Game 7s, died Friday of congestive heart failure at Northwest Community Hospital in Arlington Heights, Ill. He was 81. Skowron helped the New York Yankees win four titles in the 1950s and 1960s and he won another with the Dodgers in 1963. “There weren’t many better guys than Moose,” said former teammate Yogi Berra, the only other player with three Game 7 homers in the Series. “He was a dear friend and a great team man. A darn good ballplayer, too.” Skowron became a star first baseman with the Yankees and went on to appear in eight All-Star games over six seasons.
