According to the Seattle Times, Mariners GM Bill Bavasi has been looking at John Thomson or Tomo Ohka as possible additions.
A month ago, the Mariners requested the medical files on Thomson and seemed close to signing him. The 33 year-old had a rough year health-wise in 2006, so those files were probably pretty thick.
Haven’t heard much on Ohka in the past few weeks, though the Cards, Nats, Red Sox, Diamondbacks, Pirates, and Mariners have expressed interest in the past. Maybe he’s waiting for Mulder to sign first. Here’s my Ohka profile if you’re interested.
