Roy Oswalt On the Move?

Just very recently, I happened to write a column about the MLB trade deadline and at the bottom I mentioned that I thought Roy Oswalt would be staying with the Houston Astros.  Apparently, I was wrong.. very, very wrong. 

It now appears that Oswalt is on the move to the Phillies, who traded for and then traded ace Cliff Lee last year.  In return, the Astros are rumored to be getting young left hander, JA Happ and at least two more minor league players.  Happ busted into the MLB scene last year going 12-4 with a 2.93 ERA including 3 complete games and 2 shutouts.  This year, he's been fighting the injury bug and had walked a lot of guys in the few innings he's pitched. 

One rumor has one player being, Jonathan Singleton, a 19 year old 1B that is in A ball.  Looking at Singleton's stats he appears to be have a good eye and developing power with 12 HR's and 18 doubles so far this season.  I'd assume the other player would be a pitcher, but we all already know how accurate my assumptions can be. 

With Lee and Oswalt already moved, Cubs SP Ted Lilly might be the next best starting pitcher known on the market.
