Don Mattingly New York Yankees signed game used bat is a Louisville Slugger model C243 dating from the 1992-93 labeling period. Black ash bat displays outstanding use including a handle crack, ball and seam impressions, and some checking to the barrel. Measures 33.5 ounces and weighs 29.8 ounces, number 23 is written on the knob in fine point marker and Mattingly has signed between trademark and barrel stamp in 9/10 silver Sharpie. This dates from the later stages of his exceptional career, when chronic back problems began to take their toll, though he did account for 31 homers with 172 RBI in the two-year period for which this treasure is labeled. His nine Gold Gloves only tell part of the story, as this bat was wielded by the man with one of the sweetest swings in history. Comes with PSA/DNA LOA grading a GU 9 (note that the grade is for game use only and the LOA offers no opinion on the signature).
