"Big Mac", as fans lovingly call first baseman Willie McCovey, used this bat at the end of his career, in 1980 with the San Francisco Giants, the team he originally played for during his first 14 years in baseball. The Powerized Louisville Slugger, "Genuine M110", has the number "44" written on the knob in black marker. Both the knob and barrel ends are flat, as McCovey liked them this way. The uncracked bat shows very light use. It measures 35.5" long, and weighs 35.2 oz.
