At Shea Stadium on May 30, 2003, the Atlanta Braves go deep four times off former teammate Tom Glavine to tie a National League record by hitting 55 home runs in a calendar month.
The New York Giants (July, 1947) and the Cardinals (April, 2000) are the other teams to accomplish the feat.
It is ironic this happened against Tom Glavine. With 164 victories during the 1990s, Glavine earned the second highest amounts of wins as a pitcher in the National League, second only to teammate Greg Maddux’s 176. He was a five-time 20-game winner and two-time Cy Young Award winner, and one of only 24 pitchers (and just 6 left-handers) in major league history to earn 300 career wins.
