I saw last night one of the most unpleasant incidents I’ve ever seen on a baseball diamond. Naturally it came from a Red Sox.

With Alex Rodriguez hitting for the first time last night, Red Sox starter Ryan Dempster threw at him on the first pitch. The ball actually went behind Rodriguez. Then he threw high and tight on the next two pitches. Then, apparently upset that he’d missed the first time, Dempster hit A-Rod in the back, not far from the head.

In a moment that I’d love to see them explain to their children, the Boston animals fans roared with approval.

This from a city whose players—and players’ sons—commit murder. (And the Jerry Remy thing is so deeply sad.)

How Dempster was not immediately thrown out of the game, I don’t understand. Yankee manager Joe Girardi, to his credit, defended his player so forcefully that he was thrown out of the game. As a parting shot, he called Dempster a “fucking coward,” which he is. Standing 60 feet away from someone and throwing a baseball at 90-plus miles an hour at his body isn’t a principled move, and it’s certainly not a courageous one. Now Dempster doesn’t even have the balls to take responsibility for his actions and admit that he did it on purpose. I guess he doesn’t want to get suspended.

As the Globe’s Nick Cafardo writes,

What was served by this act by Dempster? That he and other players hate A-Rod? They already hate him.

Is A-Rod the first guy to take steroids? Did pitchers plunk Barry Bonds because he took steroids? Or Mark McGwire? Or Sammy Sosa? Did they plunk Melky Cabrera after he returned from his 50-game suspension?

Rather convenient of Cafardo not to mention the possibility that, well, certain Red Sox players have surely taken steroids.

I understand that Alex Rodriguez isn’t a well-liked guy. He’s certainly not my favorite Yankee. But what happened last night was bush league even by Boston standards. Ryan Dempster and the Red Sox fans have done their team—and their organization—an enormous disservice. Let’s hope that this move backfires and causes some of the fans and players in baseball to reconsider their behavior towards A-Rod.
