A minor league baseball game had a four-legged interruption during the 1st inning on Wednesday ... when a bat dog named Rookie stormed the field -- and it was adorable!!
The cute moment happened during the Buffalo Bisons' home game against the Lehigh Valley IronPigs at Sahlen Field ... a matchup that had Rookie filling in for bat-retrieving duties.
But, Rookie was fully prepared to go above and beyond his role to help out the Buffalo squad any way he could ... so he raced out onto the field in the middle of all the action!
