With more than a few players having seasons ranging from "Disappointing" to "Disastrous," Madrid is rebuilding. Thus pretty much anyone on the team not named Sizemore or Liriano is available.
This includes:
Josh Hamilton Carlos Zambrano Scott Downs (1.78 ERA in 78 adjusted IP, 5 Saves) Ryan Theriot (.378 OB full-time SS) Jayson Werth (.273 / .363 / .498, 24 HR 20 SB 1 CS) Kevin Gregg (29 Saves, 3.41 ERA) Brett Gardner (NYY CF of 2009 and beyond)
Others also available, although I'm not looking to trade guys at the likely nadir of their value (eg Cano, Wang, Posada, Swisher, Betancourt).
