Baseball fans, rejoice! The greatest rivalry in sports has emerged from the dank, desolate cellar it has been in for years and has shaken off the cob webs. The Red Sox / Yankees rivalry finally has some weight to it after a long break in which it seemed more likely that you would catch a player from either squad laughing about a recent round of golf together than you would see them engaging in a round of fisticuffs. In fact, it had been 14 years since Jason Varitek infamously burnished his glove into A-Rod’s squawking pie-hole. As great as the Red Sox / Yankees rivalry is, this latest fight between Joe Kelly and Tyler Austin highlights what Major League Baseball has been missing recently: gritty, hard-nosed play.
