Louisville Slugger model K75 was used by Alvin Davis with the Seattle Mariners between 1986 and 1989. Bat shows excellent use. Numerous ball marks and seam impressions are visible on the right barrel surface. Slight swelling from repeated contact. The handle has a moderate to heavy coat of pine tar. It is cracked at the mid-handle. Very small chip is missing from the crack. The knob has his #21 and either a plus sign or a cross. Pen mark appears to read 34 1/3, but due to the size of the writing and some wear, it could be 34 1/2. I would guess to be the shipped weight, similar to Rawlings bats. His #21 is also written on the barrel end.
