MLB's Dusty Baker -- Dances with 107-Year-old Legend ... At Nats Game

Virginia McLaurin can't be stopped!!

The 107-year-old -- who famously danced with President Obama AND the Globetrotters -- hit up the Washington Nationals game Thursday night and busted out some moves with manager Dusty Baker!

Virginia was honored as part of Black Heritage Day at Nationals Park -- and even got a custom jersey with the #107 on the back.

The crowd loved her. The Nationals won. The dancing was awesome.
