According to Ken Rosenthal of Fox Sports, the Astros will be receiving JA Happ along with two other players, pending Oswalt’s approval. Rosenthal recently tweeted:
Deal is 3-for-1. Happ in. Astros would pay “very significant” part of Oswalt’s remaining salary, which is over 23M.
With Werth likely staying, the Astros will be assuming a large part of Oswalt’s salary. Hopefully this leads to better prospects in the deal; a JA Happ centerpiece trade is far less than ideal.
