Battle of the Bases

Battle of the Bases is a military softball tournament, presented by the Washington Nationals, that serves as an extension of the intramural season at each of the military bases in the National Capital Region.

Teams of active duty service members from all six branches, playing across all National Capital Region installations, participate in the tournament. Preliminary rounds of the Battle of the Bases will be held to determine which bases will play in the championship game under the lights at Nationals Park. The Championship game will be a postgame event following the September 26, 4:05 p.m. Nationals game against the New York Mets.

The Washington Nationals provide, at no cost to the service branches, a Nationals-branded jersey and cap to each man or woman participating in the base-affiliated intramural softball league. Teams are differentiated through the use of a variety of styles and colors of jerseys and caps.

Through the Nats on Base initiative, the Nationals aim to provide year-round experiences that contribute to the quality of life for service members and their families in the Washington D.C. region, reaching them where they live and work – as well as in-Park. The team works with regional and base leadership to develop programming and identify outreach opportunities at local installations.

The Nationals reserve the right to change any and all 2026 access, benefits, promotions, seating locations and events (including, without limitation, location, dates and times) without notice based upon: 1) federal, city, state and/or local government orders, mandates or restrictions; and 2) other reason as determined by the Nationals and/or Major League Baseball in their sole discretions.
