I learned about Matt when he was a prospect in the Padres system, with High Desert back in 1991, where he had hit .341 with 15 home runs and looked like a great prospect. I was a bit surprised when he was part of the Gary Sheffield deal, but he was with Milwaukee by 1993, putting up a .687 OPS in 23 games. He only really managed to stick for a full season in 1995, and only got over 100 OPS+ in 1998, for two years. So he turned out to not be that great after all.
Still, I have fond memories of him in a fantasy baseball game that I created way back in the day, and was giddy at the prospect of getting his autograph.
