Eddie and Johnny O’Brien became the first pair of twins to play for the same team in the same game

On May 10, 1953, Pittsburgh infielders Eddie O’Brien and Johnny O’Brien become the first twins to play for the same team in the same game when Johnny enters the nightcap of a Giants game on defense and Eddie later pinch runs. But the Giants take the twin bill, 4 – 0, behind Sal Maglie’s 3-hitter, and 3 – 2. In-game 2, Jim Hearn comes within two outs of his 13th straight win over the Pirates but falters and Frank Hiller wins in relief. Bobby Hofman’s pinch home run in the 9th wins it.
