Bill Madden of the Daily News reports that Mariano Rivera was held out of last night's action due to a sore shoulder.

Girardi doesn't seem concerned, according to the report, and Mariano shared a similar sentiment. An earlier report by Andy McCullough of The Star-Ledger said that Mariano did not travel with the team to Seattle, due to "personal reasons."

Girardi expects Mo to be available tonight. "I'd be shocked if he's not ready tomorrow," he said. Whatever it is, we hope it's nothing serious.
