From Jayson Stark:

Two sources told ESPN.com that the Detroit Tigers have made the largest offer, amid speculation around the industry that that bid is in the range of one year, $7 million. There were indications the sides were still discussing a possible two-year deal. But even the Tigers' one-year offer appears to be the biggest offer on the table.

The Atlanta Braves and Tampa Bay Rays have also remained in the bidding, with both teams talking about one-year contracts for fewer total dollars than the Tigers' offer. MLB.com reported that the Braves' offer was for less than $4 million. A source indicated the Chicago White Sox also have expressed late interest.

So there's that.
