The Expos return ?

The Nationals will throw it back to 1969 and recognize their Canadian heritage when they host the Kansas City Royals at Nationals Park on July 6. For the first time, Washington will wear Montreal Expos throwback uniforms — specifically, the powder blue away jerseys and pants the expansion franchise wore with its classic tri-color cap during its inaugural season 50 years ago.

The Royals, who also were an expansion team in that 1969 season, will wear throwback versions of their original road gray uniforms featuring “Kansas City” in blue script. Incidentally, Montreal was once home to a minor league team nicknamed the Royals, for which Jackie Robinson played in 1946. If you’re wondering why the Nationals will wear road throwbacks at home, it’s because the Expos’ away uniforms are more striking than their original home whites.
