The Fredericksburg Nationals are a Minor League Baseball team that is the Single-A affiliate of the Washington Nationals. They are located in Fredericksburg, Virginia, and play their home games at Virginia Credit Union Stadium, with a capacity of 5,000 people.
In June 2018, Potomac Nationals owner Art Silber announced that he had signed a letter of intent to build a new stadium in Fredericksburg, Virginia, that would open in April 2020. The 5,000-seat multi-purpose stadium will include a 300-seat club facility and 13 suites. 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.
A groundbreaking ceremony was held on February 24, 2019, but construction work did not begin until July or August 2019. On September 25, 2019, general manager Nick Hall said, "We're 100 percent planning on opening April 23." MASN reported on January 13, 2020, that Hall had said that construction was on schedule and that he was confident the venue will be ready for the 2020 season. With the 2020 season start postponed due to the COVID-19 pandemic, the Nationals held a virtual opening day on April 23, 2020. Hall said that the stadium was baseball-ready though construction was not yet complete, even though, with construction deemed as essential business, "The construction progress has gone off without a hitch." Construction was continuing at the start of June 2020.
As part of a process to give the team a new name that included Fredericksburg, a "Name the Team" contest that began in April 2019 received more than 2,400 responses on the team name, colors, mascots, and ways to incorporate local history and culture. 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."
The teams uniforms were revealed on November 16, 2019, along with a Mary Washington logo at an event on Mary Washington's 311th birthday.
In March 2020, the team unveiled their new mascot, Gus, described as "fat and fluffy" with purple fur and bright green eyebrows.
The start of the 2020 season was postponed due to the COVID-19 pandemic before ultimately being canceled on June 30. With no minor league season to play, Fredericksburg became the alternate training site for the Washington Nationals, hosting players who were not on the active roster, as well as a number of minor league players and instructors, during the 2020 season.
Before the Fredericksburg Nationals could play a game at the Class A-Advanced level, the team was notified in December 2020 that it would need to accept relegation to the Low-A level to continue play as an affiliate of the Washington Nationals. Silber confirmed the Fredericksburg Nationals would continue their affiliation with Washington at the new level for 2021 and beyond. They were organized into the Low-A East.
Fredericksburg began competition on May 4, 2021, with a 16–3 loss to the Lynchburg Hillcats at Bank of the James Stadium in Lynchburg, Virginia. The Nationals played their first home game at FredNats Ballpark on May 11, 2021, losing to the Delmarva Shorebirds, 7–5, with 2,065 people in attendance.
In 2022, the Low-A East became known as the Carolina League, the name historically used by the regional circuit prior to the 2021 reorganization.
