6:52pm: The Braves and Mariners have inquired on Upton along with the Rangers, major league sources tell Ken Rosenthal and Jon Paul Morosi of FOX Sports. One source said that Atlanta “made strong overtures” for Upton earlier in the offseason but came away thinking that the Diamondbacks were not motivated to trade him.
The Mariners are particularly eager to add a hitter and some have gone so far as to say that they're desperate to do so. They have checked in on the Dodgers’ Andre Ethier and the Marlins’ Giancarlo Stanton, according to sources. Upton might be the Mariners' most realistic pursuit, according to one source with knowledge of the team’s thinking. The M's have had “on-and-off” discussions with Arizona throughout the offseason, but Upton is not inclined to remove them from his four-team no-trade list.
3:44pm: Facing a surplus of outfielders following their deal with Cody Ross, the Diamondbacks are once again “very much open” to talking about trading Justin Upton, ESPN.com’s Buster Olney reports (all Twitter links). Their specific demands have changed, Olney notes.
Diamondbacks executives have viewed the Mariners as a possible trade partner for Upton, according to Olney. However, the Mariners are on Upton’s no-trade list, Jon Heyman of CBSSports.com reported earlier in the offseason (Twitter link). The Blue Jays are also on the list, which is partially in place to provide Upton with leverage in talks.
Some officials are now convinced the Diamondbacks will trade Upton rather than Jason Kubel, Olney reports. MLBTR readers disagree. Approximately 34% of nearly 10,000 voters said today that they expect the Diamondbacks to address their outfield depth by trading Upton, but approximately 45% expect Kubel to be moved.
The Rangers, Diamondbacks, Rays and Indians discussed multi-team trade scenarios involving Upton at the 2012 Winter Meetings. Texas, Seattle and the Mets now seem like potential fits in my view.
