Brian Wilson

The Diamondbacks had insisted on receiving Major League-ready talent in any trade for Justin Upton, but were willing to accept prospects in last week's proposed deal with the Mariners that Upton blocked with his no-trade clause.  D'Backs GM Kevin Towers tells Nick Piecoro of the Arizona Republic that the change in philosophy was due to the rising cost of free agents and the fact that the Snakes had added outfield depth in Cody Ross.

"It’s easier to do more of a prospect-driven deal than before. To me, it would have to be the right prospects," Towers said.  "We’re targeting people’s best prospects and upper-level guys that we think are close — if not (major league-ready) this year, then next year.”

Some more news from around baseball…

• The Diamondbacks seem intent on trading Upton, leaving MLB.com's Matthew Leach puzzled at why the club would move a talented young player on a controllable contract.
• The Mets haven't given up on the possibility of offering Brian Wilson a Major League contract, reports Newsday's Marc Carig (Twitter link).  We heard earlier today that the Mets were unimpressed when they watched Wilson throw over the weekend.
• The Braves have one of the least-profitable TV deals in baseball but team CEO Terry McGuirk says that low broadcasting revenues aren't hampering how the club does business, McGuirk tells David O'Brien of the Atlanta Journal-Constitution.  The Braves have 14 years left on their current TV deal, which McGuirk describes as “iron-clad."
• Athletics GM Billy Beane said it was difficult to move a highly-regarded pitching prospect like A.J. Cole, CSN Bay Area's Casey Pratt reports. However, the GM said it had to be done to help the A's contend in 2013.  "We're shifting all of our focus on the Major League club and trying to take as much advantage as we can of the opportunity we have," Beane said.
• Beane said he prepared to go with a platoon of Derek Norris and George Kottaras behind the plate, MLB.com's Jane Lee reports (Twitter links).  "Only if it was John Jaso" would he have made a move to improve Oakland's catching.  Beane said he had been trying to acquire Jaso from the Mariners over the last couple of months.
• Buster Posey tops the list of baseball's best 25-year-old players, according to ESPN's Keith Law (ESPN Insider subscription req'd).
• Cubs president Theo Epstein told reporters (including Paul Sullivan of the Chicago Tribune) that Edwin Jackson's age and track record made the team comfortable enough to sign him to a big free agent contract. 
• In another item from Sullivan, Epstein said that he expects the Cubs to contend in 2013 despite the fact that they're still ostensibly rebuilding.  "Otherwise, there’s no reason to show up or build a team,” Epstein said. “It’s postseason or bust every year. That’s what our goal is."
