Roy Oswalt has agreed to waive his no-trade clause, clearing the way for the trade to the Phillies.

The trade will send J.A. Happ and two prospects, Anthony Gose and Jonathan Villar, to the Astros in return for Oswalt. The Astros will also pick up $11 million of the $23 million still owed on Oswalt’s contract.

It had been rumored that Oswalt was demanding that the Phillies agree to pick up the option the 2012 year of his deal, but that wasn’t necessary. The Phillies are required to pay Oswalt $2 million as a buyout for that year instead of $1 million though.

The Phillies were also able to make the deal without trading Jonathan Singleton, whom it had been rumored that the Astros were asking for.

Oswalt will make his first start for the Phillies on Friday, against the Nationals.
