I've been reading that Billy Wagner is ahead of schedule in his rehab and may be ready to pitch in August. If that's the case, it raises an interesting scenario - on one hand, a bullpen with Rodriguez, Putz, and Wagner is downright terrifying. On the other, if a team is willing to wait a couple weeks (since the non-waiver trade deadline is July 31st), Wagner makes for interesting trade bait. Or, maybe the Mets would be willing to deal Rodriguez or Putz to a contender desperate for a closer and take their chances with Wagner.
I know it sounds nerdy, but thinking about stuff like this is one of the reasons baseball is my favorite sport.
