NEW: Phillies' minor league baseball team bat dog takes a dump in the infield during her debut.
The 10-month-old Labrador retriever, Lucy May, was seen chaotically running through the infield before taking a potty break.
Lucy May had been training for months to take on the new position.
"The word my fiancé and I used was mortified. It felt like an eternity of her going in that dugout. When she squatted I definitely went to panic mode," said the dog's owner Andrew Davis.
