11:37pm: The Padres and D'Backs found no match in trade talks about Upton or Jason Kubel, reports Jack Magruder of FOXSportsArizona.com (on Twitter). San Diego doesn't want to move Headley and they don't have a spot for Kubel with Carlos Quentin on the roster.
3:27pm: The Padres and Diamondbacks have had on-and-off discussions about a deal involving Justin Upton and Chase Headley since July, according to Ken Rosenthal of FOX Sports. However, those talks have yet to result in a deal.
Even though that deal hasn't worked out, the Diamondbacks continue to discuss Upton with other clubs, including the Rangers and Mariners while also considering offers for Jason Kubel. The Rangers want to build a package around third baseman Mike Olt rather than shortstop Elvis Andrus or infielder Jurickson Profar and they're willing to add a top pitching prospect and a third quality piece to the package, sources say.
However, sources tell Rosenthal that the D'Backs believe they could make an even better deal for Upton with another club like the Mariners, who are aggressively trying to add a power hitter. However, as we've heard before, Seattle is on Upton's four-team no-trade list and he's not inclined to approve a deal to the M's. The Mariners might be able to change Upton's mind with a lucrative contract extension.
Earlier this week we learned that the Braves have also inquired on Upton.
