He may have not played with Demarini but he definitely had a prototype Demar bat in the circa late 80's/1990ish...
My brother talked to him about it this past weekend. We all shared the bat one weekend in a backyarder
The bat was silver with yellow writing and actually had a loose handle as if a nail was holding it together with the bat.
Bat was fire and lasted that one weekend. It was never sold as I think the first real demarini was silver and had black writing.
