This Saturday Major League Baseball and all 30 Clubs will continue baseball’s tradition of honoring those whose lives were affected or lost on September 11, 2001, and pay tribute to the men and women who continue to bravely serve our communities and country, 20 years after the tragic events of that day.

Home Clubs may recognize the day with solemn ceremonies, which may include a moment of silence, and a special PSA provided by the National September 11 Memorial & Museum to be played in ballparks. A “We Shall Not Forget” silhouetted batter ribbon will be displayed throughout ballparks and on special line-up cards and base jewels.

Representing some of the most-affected cities of the September 11th attacks, the New York Mets and New York Yankees will play each other on 9/11 for the first time, while the Pittsburgh Pirates will host the Washington Nationals.

In Pittsburgh, families of the brave passengers on Flight 93 will be recognized and honored on-field at PNC Park alongside military members and first responders.

In addition to several notable pregame ceremonies, the Mets and Yankees, whose game will be televised by FOX, will wear uniforms adjusted to commemorate the day, with specific details including:

• All players, managers, coaches and on-field personnel on the New York Clubs will have the option of wearing the New Era caps of one of New York City’s first responder agencies, including Fire Department of New York (FDNY), New York Police Department (NYPD), Port Authority of New York and New Jersey Police Department (PAPD), Department of Corrections (DOC) or Department of Sanitation New York (DSNY);

• The American flag will be worn on the upper-back portion of jersey tops, as both Clubs did following 9/11;

• The Mets home white uniforms will be altered to have "NEW YORK” across the front of their jerseys to represent the city, and will be in the same design and color scheme as those worn at home during the 2001 season;

• The Mets will also have the embroidery replicated on the right sleeve of the jersey that shows the flag and 9-11-01 as seen on the jerseys when the Mets returned to playing after 9/11.

All other on-field personnel including players, coaches and umpires will wear caps with a side patch of the ribbon during games. The Toronto Blue Jays will wear caps recognizing both the United States and Canada. MLB will donate 100% of its licensed royalties from the sales of the caps to the National September 11 Memorial & Museum.

Federal law recognizes September 11 as a National Day of Service. As such, employees at the League Office, including Baseball Commissioner Robert D. Manfred, Jr., will participate in a service project in collaboration with 9/11 Day at the Intrepid Air, Sea & Space Museum in New York City to pack meals that will be distributed by City Harvest. Mets alumni, including Edgardo Alfonzo, Rey Ordoñez and Glendon Rusch, as well as Yankees great Willie Randolph, also will participate. 9/11 Day, which was created in 2002, is a 501(c)(3) nonprofit whose mission is to rekindle the extraordinary spirit of unity and compassion that arose in the immediate aftermath of the 9/11 tragedy, and to inspire Americans and others to do good deeds that help to create a better and more peaceful world. Across the nation in 10 cities, 9/11 Day is organizing in-person volunteer projects, where thousands of volunteers will come together to help pack dry non-perishable meals that will then be donated to local Feeding America-affiliated food banks. Additionally, several other MLB Clubs will participate in their own service projects in partnership with 9/11 Day or other organizations in recognition of 9/11.

Earlier this week on Tuesday, at the invitation of the United States Department of Defense, MLB participated in the special Wreaths of Remembrance event at the Pentagon 9/11 Memorial. MLB was represented by Senior Vice President of On-Field Operations Raul Ibañez.

MLB Network will air its new MLB Network Presents documentary Remembering the Game for New York tomorrow at 1:00 p.m. and again at 5:30 p.m. ET. New York area natives and former Major League Baseball players Mark DeRosa (Carlstadt, NJ), John Franco (Brooklyn), Steve Karsay (Queens), Al Leiter (Toms River, NJ), Dave Martinez (Manhattan) and Jason Marquis (Staten Island) will relive participating in the memorable and emotional September 21, 2001 game between the Atlanta Braves and New York Mets at Shea Stadium, which marked the first major sporting event and Major League Baseball game held in New York following the attacks. Following Remembering the Game for New York, MLB Network will cover the day’s events commemorating the anniversary on MLB Tonight at 6:30 p.m. ET. MLB Network Showcase featuring the Yankees at Mets tonight at Citi Field will also cover the September 11th remembrance throughout the telecast with Bob Costas, Tom Verducci and Ken Rosenthal on the call at 7:00 p.m. ET.

The official social media channels of MLB and all 30 Clubs, reaching fans across various platforms, will deliver messages of support and remembrance. In addition, MLB.com, the 30 Club websites, the MLB app and MLBCommunity.org will provide complete coverage of the day’s ceremonies and perspectives through columns, news articles, multimedia and photographs across the league.
