So now it's Mags/Rivera/Mauer for Sizemore/Lee/Zimmerman. I think I'd still do that, depending on who you still have getting saves and who your catcher would be. Your getting the better end of this trade on (Sizemore>Mags, Lee>>Rivera), and Zimmerman should be better in the 2nd half (his BABIP is around .260 or something awful right now, he's on pace for 25 HR and 85 runs and 85 RBI). If you can get him to take Maddux or Morris instead of Mauer, then that's even better. It's worth noting that Mauer's injury is supposed to bug him the rest of the year, and it shows in his performance since returning.

Giving up Bell or Betancourt shouldn't be too bad, especially since you should be able to replace them pretty easily (even if your league is using holds as a category). Maybe they would take a Maddux / Bell combo.
