The Yankees and Mets put their differences aside to create "one unified New York" on the 20th anniversary of the Sept. 11 terrorist attacks.
The teams sported jerseys reading “New York” and wore hats from the city's various first responders. The clubs toed the line together, alternating players from both teams.
Several members of the 2001 teams attended the game at Citi Field, including former Mets manager Bobby Valentine and former Yankees manager Joe Torre, who simultaneously threw the first pitch together.
The Mets were the first professional sports team to host a game in New York City on Sept.
