10:40am: Larry Stone of the Seattle Times tweets that the Mariners will also get a player to be named later, and it could be a "pretty significant name." The Tigers may make one more trade before tomorrow, tweets Jon Paul Morosi.
10:29am: The Mariners well also receive third base prospect Francisco Martinez in the trade, tweets Knobler.
10:09am: The Tigers will receive Fister and Pauley for Furbush, outfielder Casper Wells, and more, tweets Knobler.
10:03am: The Tigers acquired Fister, tweets SI's Jon Heyman.
9:30am: The Tigers are "closing in on a deal" for Fister, reports Knobler. In another tweet, he indicates that Mariners reliever David Pauley may be involved.
9:05am: Lefty Charlie Furbush is among the players expected to go to Seattle in a Fister trade, tweets Danny Knobler of CBS Sports. The Tigers are trying to get a reliever other than Brandon League as well.
8:48am: The Tigers are making progress on a deal for Mariners righty Doug Fister, tweets ESPN's Jerry Crasnick, with hopes of getting something done today.
Fister, 27, has a 3.33 ERA, 5.5 K/9, 2.0 BB/9, 0.43 HR/9, and 46.4% groundball rate in 146 innings this year. His walk rate ranks seventh in the AL, his innings total tenth. His 6.95 innings per start average is a welcome contrast from the Tigers' non-Verlander starters, who all average around six. Drafted in the seventh round in 2006, Fister never cracked a Baseball America top 30 Mariners prospect list, but he's become a solid mid-rotation innings eater. He's under team control through 2015 and won't be arbitration eligible until after next season.
GMs Dave Dombrowski and Jack Zduriencik hooked up on a trade almost exactly two years ago, when the Tigers acquired Jarrod Washburn, according to our Transaction Tracker.
