The Arizona Diamondbacks are still listening to offers for right-fielder Justin Upton.
According to FOXSports.com writer Ken Rosenthal, the D-backs and Padres were talking about an Upton for Chase Headley swap but those discussions have not advanced.
Rosenthal reported the two teams were talking about a potential trade involving both players since July.
The D-backs are still looking to find a suitor for Upton and have talked with others teams, including the Texas Rangers and Seattle Mariners. The Mariners are on Upton's no-trade list, which could complicate a deal with Seattle. The Atlanta Braves have also expressed strong interest in obtaining Upton.
Arizona is still entertaining offers for left-fielder Jason Kubel but with Upton's reasonable contract and high upside he could net a far larger package in return.
Headley hit .286 with 31 home runs and an NL-best 115 RBI. He finished fifth in the NL MVP voting in 2012.
Upton batted .280 with 17 longballs and and 67 RBI for the D-backs.
