I just heard Cashman being interviewed on the YES postgame and he stated that A-Rod has been placed on the 15-day DL as a result of re-aggravating his quad over the weekend in Cleveland.
In medical terms, the MRI revealed that he has a Grade 2 quadriceps strain.
Damn. Who's next?
UPDATE:
Pete Caldera has this little nugget on the corresponding roster move:
Cashman said the Yankees (14-14) were expected to call up another pitcher, possibly reliever Chris Britton, since Hughes taxed the bullpen again. Wilson Betemit (conjunctivitis) is improved enough to begin a rehab assignment at Class AAA Scranton/Wilkes-Barre today, and he could fill A-Rod's roster spot later this week.
Chris Britton? Are you kidding me? I hope he didn't unpack his suitcase.
At this point, I don't care who they recall from Scranton as long as Girardi uses him. It makes no sense to have a fresh body sitting in the pen to simply rot while the rest of the pen not named Mo or Joba continues to get overworked.
