Hi Guys

I have a mcgwire rawlings bat (dark blue ring) with the following on the knob (MM 466 O O29 3) - looks like an early career bat 1986?

Cant find much info on him ever using a 466 0 model bat and the 3 on the knob would normally indicate 1993, but this is definitely an early career bat. Also, his number (25) is written in black marker at the top and bottom of the bat.

Any info would be greatly appreciated.
