The logo of the Carolina League Baseball team Potomac Nationals is heavily based on the flag of the United States.
Since 1984 when the Alexandria Dukes relocated to Woodbridge, Virginia, they’ve gone through several names until their received their current name and logo in 2005. The franchise is the Class A-Advanced affiliate of the Washington Nationals.
The primary Potomac Nationals logo features a baseball with two crisscrossed bats on the background and the name of the team on the forefront.
Taking into consideration the fact that there’s the word “Nationals” in the name of the team and its mascot is Uncle Sam, it’s only natural that their palette includes the colors of the American flag: blue, red, and white.
