Unsuspecting Cute Kid Plays Invisible Baseball with Oakland A's Sean Doolittle

On its surface, this video looks like an adorable little kid playing fake baseball with a kind stranger.

Unbeknownst to the kid, the stranger was Oakland A's pitcher Sean Doolittle.

Doolittle's girlfriend, Eireann Dolan, captured the sweet encounter and posted a video and pictures (with mom's OK):

Great stuff.
