Swisher went for an MRI yesterday, but the results have not been made public at this juncture. Here's hoping that it's nothing too serious, as Swisher is an important part of this team - both for this season and, hopefully, next. With the team scoring all of one run over the past sixteen innings, some good news would be quite welcome.
Update (from the LoHud Yankees Blog): "Nick Swisher has inflammation but no structural damage in his left elbow. He’s going to get treatment all day today, and he expects to continue sitting out until the pain goes away."
