Kat O’Brien notes that Jeff Karstens will start the season on the DL after straining his groin today. Having recently recovered from a similar injury, I can tell you that those take a while to heal. Meanwhile, I guess this means that either Darrell Rasner or Kei Igawa will win a spot in the bullpen. I think the Yanks would be better off with Ohlendorf or Patterson, but the tradition of having a long man — while seemingly foolish — seems to be carrying the day. We’ll know more soon.
