There were only 2 nominees in this week and it's 1:20 am.
Mike Schmidt - Aside from whoever is currently playing the Hot Corner for the Marlins (and heck, with the dude who is playing there now, I might have an argument some day), I consider Schmidt to be the best third baseman ever. Sure, he only has a lifetime batting average of .267, but he does know a little something about productivity at the plate as evidenced by his 548 homers. The dude knows more about hitting than a roomful of statisticians. I'll talk out of my ass for a bit here, but just because increased strikeouts are correlated to offensive production doesn't mean that batters should be swinging for the fences on a 2-strike count.
This leaves Bellamy and Riise. If a player hit another player in America with a golfclub, the sporting establishment would grind to a hault. ESPN would temporarily add 2 more channels. PTI would have to be an hour long. This would result in endless press-conferences and statements, and who knows, perhaps something similar to this happened in England. A similar thing may have happened in England for all I know, but that particular celebration. I don't even think T.O. would have the balls to mock an incident like that.
Way to hit your teammate with a golf club, and way to get hit by a golf club. Have a cookie Bellamy and Riise(only one though, so you're gonna have to split it).
