One injury risk for another? Beltran for Street? Both player's values are kinda iffy, wouldn't be a bad risk/reward trade to make.
With those closers your only going to be able to pry a potential risk/reward OF from an owner:
Maybe Corey Hart (if the other owner is worried about a regression)
If this is a cat based or roto league dealing Street for a speedy option like Rajai Davis or Ichiro makes sense too. (if your light on speed)
But again, you didn't post your roster.
What are you looking for specifically for your needs, and what kind of league is this? See the more information we have, the better advice we can give ya.
Speedy type OF lose some value in H2h Points based leagues, unless your Crawford or Ellsbury...the top OF are big boppers (Braun, Hamilton to prove my point). ((Or your league is set up to help out in that way...))
Try offering Street for Hart, Ichiro, Rajai Davis, maybe ellsbury (who has been hurt in the past isn't at full value yet) - if you need speed and be happy with any of these.
Maybe an OF like Hart or Beltran would be a good shot to take as well. or maybe as a last option, manny.
