70 Home Runs was not in anyone's vocabulary until 1998, when Sammy and Big Mac stole the nations attention and hearts. This is a Rawlings MAC25 MARK MCGWUIRE professional model bat. Evidence of ball marks, stitch impressions, black ink transfers and pine tar. The model number (MAC25) order number (584) and year (98) are stamped into the knob. The weight (33) is written on the knob in blue ink. McGwire has signed and inscribed the front barrel in black marker ‘Mark McGwire 70 HRS 1998’, in our opinion rating a strong 9. Length 34.5” and weight: 32.8oz. This bat is properly marked, presented to us as game used and in our opinion shows excellent use. Accompanied by a PSA/DNA letter grading it GU 9.5, as well as BECKETT letter for the autograph.
