Who threw the only baseball "no-hitter" on opening day?

On April 16, 1940, Feller threw his first no-hitter, against the Chicago White Sox on opening day at Comiskey Park. The Indians won the game, 1-0. Feller’s no-hitter remains the only one to occur on any opening day in baseball history. He pitched a second no-hitter against the New York Yankees on April 30, 1946, and his third no-hitter came on July 1, 1951, in a game against the Detroit Tigers.
