Atlanta Braves manager Bobby Cox set a new record after he was ejected from the 132nd game in his career.
Cox went seven weeks between tying and breaking the record
Cox, 66, passed the previous record of John McGraw when he was thrown out by home-plate umpire Ted Barrett in a 5-4 win over San Francisco Giants.
McGraw managed the Giants - then based in New York - until 1932, but 14 of his sendings-off were as a player.
"It's absolutely no factor. It's nothing," Cox said. "It just means I've been around a long time, that's all."
Cox's move helped calm top batter Chipper Jones, who had just struck out, and arguably prevented the player from being ejected.
Jones went on to drive home the winning run and said: "When Bobby saw I was not long for this game, he decided to take over. It worked."
Major League Baseball does not count ejections as an official statistic but the Society for American Baseball Research records 131 for McGraw.
Cox, a manager since 1978, tied the overall record on 23 June against the Detroit Tigers but managed to go 43 consecutive games without being sent from the dugout.
