Northwest Federal Field at Pfitzner Stadium is the home of the Potomac Nationals, the Carolina League affiliate of the Washington Nationals.
It was originally known as Davis Ford Park, named after the main road outside the stadium. Two years later the stadium was renamed Prince William County Stadium, as it was known for nine years. Before the start of the 1995 season, the ballpark was renamed again, this time in honor of Prince William County Board of Supervisors member G. Richard Pfitzner. As a county supervisor, Pfitzner led the charge to bring the Alexandria Dukes to Prince William County.
Upon their relocation, the Alexandria Dukes became the Prince William Pirates, after their parent club, Pittsburgh. They later adopted the name of another parent club, the Yankees, before finally taking on a local nickname. The club played as the Prince William Cannons from 1989-1998. In 1999, the Cannons adopted the name Potomac Cannons to better represent their fan base, which covers much of the Northern Virginia region. When the Montreal Expos relocated to Washington, DC, and became the Washington Nationals, the Cannons became the Class A-Advanced affiliate of the Nationals and once again adopted the name of their parent club.
Throughout the years, Pfitzner Stadium has played host to some of the best players both in and out of the Nationals organization. Current and past All-Stars such as Albert Pujols and Barry Bonds have called the stadium their home. The P-Nats parent club up in DC has sent a majority of their players through Potomac including Stephen Strasburg, Bryce Harper, Jayson Werth, Ryan Zimmerman, Jordan Zimmermann, Michael A. Taylor, Danny Espinosa and Trea Turner. Others who have made their way through Potomac through the years and are part of the Hall of Fame include Barry Bonds, Magglio Ordonez, Jorge Posada, Bernie Williams, Andy Pettitte, Ivan "Pudge" Rodriguez, and club owner Art Silber.
For four straight seasons, 2015-2018, the P-Nats have seen a player go from the P-Nats to the Washington Nationals in the same season. In 2015, IF Wilmer Difo went from The Pfitz to D.C., RHP Koda Glover did the same in 2016, while OF Victor Robles followed the same path in 2017 and ended up on the postseason roster. In 2018, OF Juan Soto played 15 games with the P-Nats, and made his MLB debut with Washington on May 20th.
Starting with the 2018 season, the stadium was re-named Northwest Federal Field at Pfitzner Stadium as part of a multi-year partnership with Northwest Federal Credit Union.
