Alex Rodriguez has worn the villain’s hat long enough to know he is disliked throughout baseball. What he doesn’t want is people throwing at him because of their opinions of him filing an appeal of a suspension. “Whether you like me or hate me that was wrong and unprofessional and silly and kind of a silly way to get somebody hurt on your team as well’’ Rodriguez said of Boston pitcher Ryan Dempster drilling him in the left elbow in the second inning of last night’s 9-6 Yankees victory over the Red Sox in front of 37917 at Fenway Park. From Dempster’s first pitch that went behind Rodriguez to the 3-0 pitch that hit him it was clear Dempster had targeted Rodriguez two days after John Lackey who didn’t throw at Rodriguez Saturday and Jonny Gomes were quoted as being miffed Rodriguez could play while appealing a 211-game suspension for performance-enhancing drug activity. Manager Joe Girardi was livid over Dempster blatantly hitting Rodriguez and umpire Brian O’Nora issuing a warning to the Yankees. “He should have thrown [Dempster] out. I don’t understand why he’s left in the game and then they give us a warning?’’ said Girardi who was ejected when he slammed his hat to the ground during the fierce argument.
