Major League Baseball and each of its 30 teams will commemorate the 11th anniversary of the September 11, 2001 terrorist attacks through a series of on-field tributes on Tuesday.
The commemorations will feature all on-field personnel -- including players, coaches and umpires -- wearing an American flag patch embroidered on the side of their caps, as well as special lineup cards and base jewels for every game Tuesday. The Blue Jays will wear customized hats displaying support for both the United States and Canada.
Prior to each game, the respective home teams at each stadium will mark the anniversary with special pregame ceremonies. The "We Shall Not Forget" MLB silhouetted batter ribbon will also be on display throughout each ballpark.
The day will also feature the re-airing of the "Nine Innings From Ground Zero" special -- developed by MLB Productions -- at noon ET on MLB Network. The network will also provide thorough coverage of the day's events across the league during its studio programming.
MLB.com, along with each of the 30 club sites, will cover the events through an array of social media, while also delivering messages of service and remembrance.
