All sources expect that Matt Treanor will rejoin the team for today's game.

According to the AP, it is already a done deal.

Assuming the AP is correct don't be surprised to see Treanor starting today.  Treanor starting would allow the team to give Olivo two days off from catching.  The club is off on Thursday.

The main reason for Treanor not to start is that Olivo is in a bit of a groove at the plate and hits have been hard to come by in this series. They could, of course, play Dontrelle in the field to pick up the slack at the plate, but I really wouldn't recommend that.
