The Alexandria Dukes moved from Alexandria, Virginia, to Woodbridge for the 1984 season and were renamed the Prince William Pirates. Subsequently, the team was named the Prince William Yankees, Prince William Cannons, Potomac Cannons, and the Potomac Nationals.
The team sought a better ballpark for at least twenty years. When Prince William County officials rejected a 1998 proposal for a $150 million sports and entertainment complex on the Cherry Hill Peninsula by the Potomac River, team owner Art Silber changed the team name from Prince William Cannons to Potomac Cannons and announced an effort to move to Fairfax County.[3] In 2000, the team proposed a $250 million stadium and apartment complex next to Fairfax County's Dunn Loring Metro station,[4] but county officials rejected it in 2001. In 2002, the team and Prince William County officials reached an agreement to build a new $10 million stadium tentatively sited next to Pfitzner Stadium.[5] In 2005, the team announced preliminary details about construction of the stadium, due to open in 2007, but with the site undecided.[6]
Another ballpark proposal began as early as 2010.[7] In 2011, Silber said he was looking for a site along I-95 in Prince William and that a stadium would be privately funded.[8] By 2012 the proposal was focused on a site on I-95 in Woodbridge. The team and the county were reported to be close to a deal in December 2016. The county would raise $35 million in municipal bonds, lease the site, pay for site preparation, construct the stadium, and lease it to the team for thirty years. The team would cover the county's annual debt service and site lease costs. The county also would build a 1,400-space parking garage next to the stadium for stadium and commuter parking. The county sought state funding for the garage starting in 2012, but the extent and status of funding was never clear, nor was the final cost of the garage.[9] Silber said that Minor League Baseball required the team to be out of Pfitzner Stadium by the end of the 2018 season.[10][11] The team opposed attempts to put the deal on the November 2017 general election ballot, saying that would delay the deal for too long.[12]
On July 13, 2017, the Nationals withdrew the proposal for the new stadium in Woodbridge after it was clear it did not have the votes to pass.[13] Silber indicated that the team could be sold to buyers outside the Northern Virginia area, but that he preferred to keep it local if possible. Potential locations included the cities of Alexandria (former home of the team when they were the Alexandria Dukes) and Fredericksburg, as well as Loudoun, Spotsylvania,[14] and Fairfax counties.[15]Maryland and Arlington County were ruled out as possibilities, and Silber indicated it was unlikely the team would find another site in Prince William, either.[14] Alexandria indicated it wasn't interested in February 2018.[16]
In January 2018, Silber announced an extension of the team's lease at Pfitzner Stadium through 2020, still needing Minor League Baseball to approve playing there past the end of the 2018 season.[17][18] Silber remained interested in moving the team and building a new stadium, in Northern Virginia—including Prince William County—or another nearby locality,[17][18] but said he was not pursuing a sale.[17]
Move to Fredericksburg
Silber announced in June 2018 that he had signed a letter of intent to build a new stadium in Fredericksburg, Virginia, that would open in April 2020.[19] The 5,000-seat multi-purpose stadium will include a 300-seat club facility and 13 suites.[20] In November 2018 the Fredericksburg city council unanimously gave final approval for the Silber family to finance, build and maintain the $35 million stadium with the city as an "anchor tenant" making an annual payment to the club of $1.05 million for 30 years.[21]
The Potomac Nationals played their last regular season game at Pfitzner Stadium on August 29, 2019.[22][23] On October 5, 2019, the team announced that it had changed its name to the Fredericksburg Nationals for the 2020 season and that its marketing nickname for the team – "P-Nats" when the team was the Potomac Nationals – would change to "FredNats."[24][25][26] Because minor league baseball for 2020 was cancelled due to the COVID-19 pandemic,[27] the Fredericksburg Nationals played their first game on May 4, 2021.[28]
