Bob Feller, Cleveland Indians pitching phenom, became the first professional American athlete to enlist during World War II. Two days after the attack on Pearl Harbor, Feller volunteered for the U.S. Navy. He served as a chief petty officer aboard the USS Alabama, first seeing action during Operation Galvanic in November of 1943. The Alabama would go on to see action during Operation Flintlock and the Battle of the Philippine Sea. Feller’s combat duty ended in August 1945, and, two days after returning home, played for the Cleveland Indians against the Detroit Tigers. The Indians won 4-2. (Naval History and Heritage Command)
