April 30, 2002, was a big day for New York Mets pitcher Al Leiter. In a 10-1 victory against the Arizona Diamondbacks, he became the first player in MLB history to have a win against all 30 of the active teams in baseball.
Leiter faced the defending champions in Arizona looking for his third win of the season. A three-hit performance with only one unearned run allowed highlighted Leiter’s historic performance.
Along with a pair of home runs from Mike Piazza, Leiter cruised to victory.
Leiter is one of those pitchers who was fortunate enough to spend enough time in both leagues to achieve this.
