12:48pm: Heyman tweets that an agreement has been reached, with only medicals pending. We'll do a fresh post once this trade is official. To reiterate: the Yankees get Curtis Granderson, the D'Backs get Edwin Jackson and Ian Kennedy, and the Tigers get Max Scherzer, Daniel Schlereth, Austin Jackson, and Phil Coke.

Sherman notes that the Yankees managed to pull off the Granderson acquisition without giving up Phil Hughes, Joba Chamberlain, or Mike Dunn.

12:35pm: Olney now says this deal is close. Sherman says medical records are being exchanged on Granderson. In another tweet Sherman says there's no deadline on the deal, but one source says it's "on the goal line." He adds that removing Dunn from the deal was key for the Yanks.

Tyler Kepner of the New York Times says the deal is "very close," and would be Austin Jackson, Coke, Scherzer, and Schlereth to the Tigers, Edwin Jackson and Kennedy to the D'Backs, and Granderson to the Yankees.

12:19pm: Rosenthal says the revised deal has the Tigers getting two players from the Yanks rather than three, with Coke or Dunn out. AOL FanHouse's Ed Price tweets that the D'Backs and Tigers are awaiting signoff from the Yankees, and expect an answer within 40 minutes.

11:51am: Morosi sees progress being made, while MLB.com's Steve Gilbert thinks this thing is close; the Arizona Republic's Nick Piecoro agrees.

11:24am: More from Olney – the D'Backs are aiming to get Edwin Jackson and Kennedy in the deal. Olney speaks of "growing confidence on at least two of the sides" involved, and his sources have the odds of a deal in the 20-30% range. One Heyman source said 50%.

11:15am: Rosenthal and Morosi note that the Yankees and Tigers are open to making a Granderson deal and leaving the D'Backs out of the discussion. Still, the three-team talks are ongoing and fluid, with the Tigers requiring a "high-ceiling, close-to-the-majors center fielder" as part of the Granderson package. Austin Jackson could be that player.

ESPN's Buster Olney says it's the Tigers that re-ignited the three-way talks, and they've lowered their asking price.

10:33am: Heyman tweets that this deal is "back with a chance." Mark Feinsand of the New York Daily News agrees, noting that the Tigers "may be caving" on the price for Granderson. He says the Yanks would likely downgrade one of the pitchers, most likely Dunn. Wouldn't be the Winter Meetings without three-team trade scenarios and the constant back-and-forth.

10:30am: Just to add a little intrigue, ESPN's Buster Olney says "one idea raised" was the Yankees getting both Granderson and Jackson. Regardless, two of the teams involved backed out of this three-team mess.

8:29am: SI's Jon Heyman tweets that this one "looks very unlikely." In his scenario Heyman had Daniel Schlereth, Scherzer, and more going to Detroit. He adds that the Yankees are saying no to the deal, which would've cost them the four prospects named below. Similarly, Morosi now finds the chances of this one to be "not good" because the Yankees balked at the price.

7:35am: Buster Olney adds that the talks progressed to the point where only one team liked the deal; he's not sure whether talks can resume or not.

TUESDAY, 7:00am: Morosi tweets that the deal is still a possibility as of this morning, according to one source.

MONDAY, 11:23pm: Joel Sherman of the New York Post hears that the Tigers were never satisfied with the blockbuster talks.

10:05pm: The D'Backs pushed for a blockbuster three-way deal with the Yankees and Tigers today, only to see one of those two teams veto it, according to Jon Paul Morosi and Ken Rosenthal of FOX Sports. However, the teams are discussing the following scenario.

The deal would send Curtis Granderson to the Yanks, along with a prospect or two from the D'Backs. Arizona would obtain Edwin Jackson from the Tigers and Ian Kennedy from the Yankees. The Tigers would obtain Max Scherzer from the D'Backs and Austin Jackson, Phil Coke and Michael Dunn from the Yanks.

Talks are apparently at an "impasse" now, though the D'Backs continue to push for a trade.
