Twice during the season, the rivalry saw peace. The Mets opened the 2001 season playing the Braves at Turner Field. When the Mets walked into their clubhouse prior to their workout before opening day, officials at the stadium greeted them by writing on the clubhouse message board: "Welcome to the National League champion New York Mets." A week later, the Mets hosted the Braves at Shea Stadium when they raised their 2000 National League Champions banner. During pre-game festivities on September 21, 2001 at Shea Stadium, both the Braves and Mets paused to remember the victims of the terrorist attacks in New York and Washington ten days before. This was the first professional sporting event held in New York since the attacks. With the Mets down 2-1 in the bottom of the eighth inning, Piazza hit a two-run home run to help the Mets win. The significance of his spirit-lifting home run has been cited as one of the greatest moments in Major League Baseball history.
