5:36pm: The A's are confident they can sign Matsui, according to Bob Nightengale of USA Today (on Twitter).
2:32pm: This morning, Susan Slusser of the San Francisco Chronicle posted the latest on the Athletics' search for a designated hitter:
- Vladimir Guerrero is now open to a one-year deal with any AL West team. The Mariners are probably not a match given the Jack Cust signing, and the Angels probably aren't planning a reunion, so this news really only affects the Athletics. Meanwhile, the Rangers still consider Vlad their best DH option and are optimistic about a deal according to MLB.com's T.R. Sullivan.
- The A's still have Hideki Matsui atop their list, though he's drawn interest from the Orioles and possibly Rangers.
- Nick Johnson, said to be fully recovered from wrist surgery, is also in the mix for Oakland.
