Jon Heyman of reports that the Phillies have reached an agreement with the Astros to acquire reliever Wilton Lopez.

(Listen to Phillies assistant GM Scott Proefrock on the Sports Bash with Mike Gill talking about the Phillies hot stove)

It's not clear who the Astros will get in return, but Heyman hears that they will receive some near major league-ready prospects.  Lopez is an excellent pickup for the Phillies, who figure to use him as a bridge to closer Jonathan Papelbon.

The 29-year-old right-hander had a 2.17 ERA and 54/8 K/BB ratio over 66 1/3 innings this season and has a career ground ball rate of 55.9 percent. It makes sense for the Astros to sell on him now, though, as they don't figure to contend in the near future.
