PITTSBURGH -- Call it a squirrelly move.
The squirrel appeared to enter from along the stands on the third-base side. He then scampered into the left-field corner.
Three members of the grounds crew were able to coax the critter into exiting the field through the bullpen gate.
The squirrel brought the home team good luck. The Pirates went on to score three runs in the inning to break a scoreless tie and won 12-1.
