Minor League Bat Dog Goes After Ball in Warm-Ups, Thinks Pitcher's Playing Fetch

Rookie, the bat dog for the New York Yankees Double-A affiliate, had a rookie moment on Tuesday.

The golden retriever, whose father and grandfather were also Trenton Thunder bat dogs, went after a ball the umpire threw to the pitcher in between innings.

Thankfully, the pitcher didn’t seem to mind. Per the Thunder’s website, Rookie started in 2013 and is still "perfecting his craft" with his dad, Derby.
