SI.com has learned that the Tigers won the claim on Ibanez and the Twins won the claim on Washburn. However, neither team was able to work out a trade with Seattle within the allotted 48 hours after making the claim.
...sources indicate that there were trade discussions ongoing between Minnesota and Seattle. However, the teams couldn't agree on a trade before the Thursday afternoon deadline.
I am going to let this sit and stew for a little while.
Matthew's Addendum: This appears to be confirmed now by the Seattle Times. Our last hope is that the Mariners put Washburn back on waivers this month. Yes, they still can do that. If a player is put on revocable waivers and is claimed, there is two days to work out a trade. If no trade was made, such as in this case, the player can be put on waivers one more time, but is automatically on irrevocable waivers. That is, if Washburn hits waivers again this month and is claimed, that's it. He's gone without even a chance for the Mariners to fuck it up. Please put him back on waivers.
