SATURDAY, 12:20pm: The D'Backs have let other teams know they're willing to trade Upton for the right package, reports ESPN's Buster Olney. "They wouldn't be pushing it this hard in the middle of the year unless they really wanted him out of there," said one official. Olney hears that the situation reminds teams of the Rockies and Ubaldo Jimenez last summer.
FRIDAY, 7:23pm: Rosenthal tweets that the teams on Upton's limited no-trade clause are unknown. He was able to block deals to the Royals, Tigers, Athletics, and Mariners back in 2010 but the list has since changed.
6:59pm: The Diamondbacks are currently 39-43 and seven games out in the NL West, and Ken Rosenthal of FOX Sports reports that they would consider trade offers from Justin Upton if they fall further out of contention. They will target a third baseman if they instead move closer to contention.
Rosenthal says GM Kevin Towers is open to any type of deal, meaning they could buy, sell, or make a veteran-for-veteran swap that helps now. Upton has been involved in trade rumors before, specifically during the 2010-2011 offseason. The 24-year-old has hit just .266/.348/.378 with seven homers this year after placing fourth in the MVP voting last season. He's under contract through 2015 for approximately $41.9MM and is the type of player that will draw interest from every other team in the league if available.
