In 2001 , the Mets finished with a record of 82 – 80 . After the September 11th terrorist attacks Shea Stadium was used as a relief center and then saw the first sporting event in New York City since the attacks , in a game vs. the Atlanta Braves on September 21 . Before the game the FDNY , EMT , NYPD , and all rescue workers were honored , Diana Ross sang " God Bless America " , the two teams shook hands to show that they were united in the face of tragedy , and Liza Minnelli sang " New York , New York " during the 7th inning stretch . In the bottom of the 8th inning the Mets were trailing 2 – 1 when Mike Piazza came to bat with a runner on first . Piazza dramatically sent Shea into a frenzy by crushing a home run to give the Mets a 3 – 2 lead and the eventual win . The game is considered to be one of the greatest moments in the history of the franchise . After the September 11 , 2001 attacks , the Mets , as well as other teams in the league , wore Red Cross , FDNY , NYPD and PAPD baseball caps . Unlike the other teams , the Mets wore these for the rest of the year , despite threats of fines by Major League Baseball
