Hall of Famer Bob Feller, who pitched for the Cleveland Indians, acknowledges the crowd before the Hall of Fame Classic baseball game in Cooperstown, N.Y., last summer. Feller, the Iowa farm boy whose powerful right arm earned him the nickname "Rapid Robert" and made him one of baseball's greatest pitchers during a Hall of Fame career with the Indians, has died Wednesday. He was 92. New York Times report here. (AP Photo/Kevin Rivoli, File, File)
