Off the top of my head, the only guy I can think of is Pudge Rodriguez. The Tigers experimented with it, albeit briefly, in 2007 and '08. It got some weird coverage down here in Texas. After he left the Rangers, the media had this weird fixation with him. Piazza never did it. Buster Posey has never done it, either. It's a real rarity. Interesting...also are you living in Texas as well? Nice to see another Texas Cheesehead!
