Louisville Slugger 125 model bat measures 35" long and weighs 31.7 ounces with model K75 stamped on knob end along with "45" written in black marker (written on end of barrel as well). The bat shows expected moderate use for a pitcher to include ball marks, stitching impressions, and several black rack mark streaks. Bob Gibson was not only a fearsome pitcher on the mound but an exceptional all around athlete. Gibson collected a total of 274 hits in his career along with 24 home runs and an impressive total of 144 RBIs. One of only a small handful of Gibson game bats we have encountered. Includes LOA from PSA/DNA (GU 8): EX-EX/MT
