Baker says Branyan is mystery free agent.

Branyan is a third baseman, who can also play first base and the outfield. At the very worst, he's a huge hitting upgrade over Miguel Cairo -- who manned both corner infield spots way too often last year. But I have a feeling Branyan will be doing more than just backing up. Let's see. Mariners GM Jack Zduriencik says he can play both spots, or serve as the DH.
