Justin Upton for Chase Headley?
The Arizona Diamondbacks and San Diego Padres have held on-and-off discussions about a trade involving those players since July, but the talks have failed to progress, according to major-league sources.
The Diamondbacks, however, continue to discuss Upton with other clubs, including the Texas Rangers and Seattle Mariners, sources say, while also considering offers for another of their outfielders, Jason Kubel.
The Rangers want to acquire Upton without giving up either shortstop Elvis Andrus or infielder Jurickson Profar. Their preference is to build a package around third baseman Mike Olt, and the team is willing to add a top pitching prospect and third quality piece to the package, sources say.
But the D-backs, sources say, believe they could make an even better deal for Upton with another club – possibly the Mariners, who are aggressively trying to add a power hitter.
