According to a report from the Bulls front office, Dale Thayer has been called back up to Tampa Bay. Digging through the Rays roster I see that Chad Bradford, the submariner we saw a while back, has been put on the disabled list. So maybe that explains why Thayer was called up.
Best of luck to Dale. We're sure gonna miss him while he's gone.
Update: A link to The Rays Party on this one, with graphs on how Dale did the last time he was called up.
