a National – inducted into the Ring of Honor. The Ring of Honor includes: Attendance Source: Spring training The Nationals hold spring training in Florida, where they play their annual slate of Grapefruit League games. From 2005 through 2016, they held spring training at Space Coast Stadium in Viera, Florida, a facility that they inherited from the Expos. In 2017, the Nationals moved their spring training operations to The Ballpark of the Palm Beaches, a new facility they share with the Houston Astros in West Palm Beach, Florida; they played their first Grapefruit League game there on February 28, 2017. On February 16, 2018, it was renamed FITTEAM Ballpark of the Palm Beaches after the Nationals and Astros signed a 12-year deal for the naming rights to the stadium that day with FITTEAM, an event brand partnership and organic products firm located in Palm Beach Gardens, Florida. Minor league affiliations The Nationals began an affiliation with the Low-A Nationals in 2005; the then-Advanced-A Potomac Nationals moved from Woodbridge, Virginia, to Fredericksburg, Virginia, before the 2020 season, and moved to Low-A play in the 2021 season. Former affiliates Nationals Dream Foundation The Washington Nationals Dream Foundation is the team's charity which is "committed to community partnerships that improve the lives of children and families across the Washington Capital Region." The foundation opened a youth baseball academy in partnership with the D.C. government, and a pediatric diabetes care center at Children's National Medical Center in partnership with the Center. The foundation also provides grants to local organizations. On August 1, 2011, the foundation, in partnership with several local organizations, formally opened Miracle Field in Germantown, Maryland, as part of an effort to encourage athletic activity in children with "mental and/or physical challenges." According to Steven Miller of MLB.com, what sets Miracle Field apart in terms of safety is its unique design, as it "is made entirely of a cushioned synthetic turf that is five-eighths of an inch thick—providing a safe surface for children in wheelchairs or with other handicaps." Radio and television The Nationals' flagship radio station is WJFK-FM (106.7 FM) "The Fan", which is owned by Entercom. Charlie Slowes and Dave Jageler are the play-by-play announcers. WJFK fronts a radio network of 19 stations serving portions of Virginia, Maryland, West Virginia, North Carolina, and Delaware as well as the District. WFED (1500 AM) had been the flagship station since the 2006
