For the Astros, they received decent value for the struggling Pence. They did not get the crowned jewels of the Phillies system in OF Dominic Brown or RHP Vance Worley, but Singleton is still a solid prospect. The Astros should be open to trading anyone on the team, including pitcher Wandy Rodriguez if the price is right.
In an unrelated note, the Seattle Mariners activated LHP Erik Bedard from the DL and can now listen to trade offers for the oft-injured lefty. As usual, look for the Yankees to be active in the market for a left-handed pitcher. We are in the calm before the July 31st storm that is the MLB trade deadline. Enjoy.
