PHILADELPHIA (AP)– A person with knowledge of the deal says Houston Astros ace pitcher Roy Oswalt, a Weir native, has agreed to waive his no-trade clause and accept a swap to the Philadelphia Phillies.

The person aware of the trade told The Associated Press that Oswalt must first pass a physical.

Houston is to get pitcher J.A. Happ and at least two prospects from the Phillies.

The two-time NL champion Phillies went into Thursday with a seven-game winning streak. They began the day 3 1/2 games behind Atlanta in the NL East.
