» May 6, 1951: Pirate P Cliff Chambers throws a no-hitter at the Boston Braves in Boston, winning 3–0. He walks eight and throws one wild pitch but hangs on to record only the second no-hit game in Pirate history. Chambers, hitting .429, drives in Wally Westlake with the 3rd run in the 8th. The loser is George Estock, a Braves reliever making his only ML start and the loss is his only ML decision. For Chambers, it is his last win in a Pirates' uniform before he's traded to St. Louis.
