Well, this isn't great news.
Tanaka's MRI showed a small forearm strain so he will be placed on the 15-day DL.

While it's good that it's not his elbow, anytime you have a strain in the pitching arm, it's not very positive news because it could be a precursor to something more.
Let's cross our fingers that it's not.
Cashman said it will conservatively be a month before Tanaka returns to mlb rotation
