Arizona GM Kevin Towers just took Justin Upton off the market. So you can forget the idea of the Red Sox trading for him.
"It's highly unlikely Justin Upton leaves the desert," he said.
At this point, I'm not sure the Red Sox have the prospects left to make a major deal unless they want to deal away Ryan Kalish, Jose Iglesias, Drake Britton, Felix Doubront or Stolmy Pimentel.
What could happen is using Marco Scutaro (or Jed Lowrie) and B-level prospects to swing a trade for bullpen help or a right-handed bat who could play left field.
Guys like Josh Reddick, Lars Anderson and Michael Bowden do not have enough value to be major chips in a trade.
