During one of his games in 1988, Don Mattingly hit a home run, got up to bat again, cracked his bat, and later gave that bat to our consignor. This 34", 32 oz. Cooper PRO 100 Professional 141 model bat shows great use. There is a repaired crack at the handle, which also shows evidence of pine tar. A few ball marks are visible on the barrel. "23" has been written in blue marker on the knob. This is the first Cooper bat we have seen used by Mattingly. LOA.
