Minor League bat dog ignores bat, takes baseball out of pitcher's hand instead

The Trenton Thunder, Double-A affiliate of the Yankees, have had a bat dog since 2002. The position has been handed down through generations: It was first filled by Chase, then Chase's son Derby, and now, after an intense training regimen, it's fallen to Derby's son Rookie.
As you can see, Rookie is an extremely good boy:

And on Tuesday afternoon, the Yankee organization rewarded him the same way they would any promising prospect: They promoted him to bat dog of the Triple-A Scranton-Wilkes Barre RailRiders.

This was Rookie's chance -- just one step away from the Show. Faithfully retrieving bats wouldn't be enough. It was time to go above and beyond.
So, after a Scranton at-bat against the Norfolk Tides on Tuesday night, Rookie took a few steps toward his usual destination ... and then peeled off and stole the baseball from opposing starter Alec Asher:

Despite the admirable effort to help the team, he was sent back down on Wednesday for a bit more seasoning:

You'll definitely be back, Rookie.
