If any at all?
I'm looking a few weeks into the future and seeing Miles struggling for playing time given that Scales is now Lou's new favorite to go to. I'm not saying Scales doesn't deserve the time but Lou, when he likes someone, tends to ride him out for all he's worth (see Marmol). Given our bullpen trouble, do you think it's possible to package Miles and maybe Heilman for a decent reliever?
I don't think a major deal is going to be done this year by Hendry. The Peavy deal seems to be shot and we don't have a desperate need at any position unless Aramis doesn't come back for a long time or gets reinjured or Fukudome returns to his second half form. What else would you change besides the bullpen? Maybe someone like Matt Capps (who I assume will turn it around at some point) or maybe someone on the Blue Jays or Orioles becomes available in the second half. I'm predicting that the Jays cool off at some point.
