Astros pitcher Roy Oswalt wants to be traded, but is owed $31 million in salary through the 2011 season. The club also holds a $12 million option for 2012 with a $2 million buyout clause. His high price tag makes a trade somewhat complicated. The Houston Chronicle writes that the Dodgers, Mets and Yankees will likely be in the race. In addition, the Braves, Reds, Nationals, White Sox and Phillies have an outside shot to land Oswalt.
