The Washington Nationals annual LGBT Pride night, Night Out on Tuesday, June 5, has already sold 3,100 tickets, sponsoring group Team DC has said.

Tickets are still available for the game against the Tampa Bay Rays, the 14th Pride night held by the Nationals.

The Gay Men’s Chorus of Washington will sing the national anthem and Team DC and the Nationals will honor the LGBTQ youth advocacy group SMYAL with the Spirit Award. In a promotional video for Night Out, Nationals reliever Sean Doolittle and his wife, Eireann Dolan, spoke about how moved they were by their visit to SMYAL.

Earl Fowlkes, chair of the DC Commission on Human Rights and President of the Center for Black Equity, will throw out the first pitch; Gen. Tammy Smith, the military’s first openly gay general, will deliver the game ball; and military veteran and transgender activist Charlotte Clymer from the Human Rights Campaign will make the “Play Ball!” announcement.

Attendees will also get a Night Out T-shirt.

The Nationals are one of 24 Major League Baseball teams that have Pride games this year.
