In , there was a moment of peace in the rivalry in the aftermath of the attacks in New York City . During the weekend of September 21 – 23 , Shea Stadium hosted the first professional sporting event in New York City since the attacks when the Mets hosted the Atlanta Braves while Yankee Stadium hosted a special memorial service titled " Prayer for America . " On June 15 , , Roger Clemens faced the Mets for the first time at Shea Stadium since the Piazza controversy . Anticipation mounted about retaliation against Clemens . Mets manager Bobby Valentine chided Clemens by saying he wore a " skirt " when compared to past pitchers who threw hard at people like Bob Gibson and Don Drysdale because Clemens did not have to bat in the American League . When the game arrived , Clemens was forced to bat and Mets pitcher Shawn Estes attempted to hit Clemens in retaliation but instead threw a pitch behind Clemens , prompting the home plate umpire to warn both benches . Estes later homered off of Clemens as the Mets won the game 8-0
