According to Jim Salisbury of CSNPhilly.com, the Phillies have halted their pursuit of Astros' right-hander Wilton Lopez.
Talks progressed to the point where Lopez was in Philadelphia to take a physical on Wednesday. However, it all came crumbling down shortly thereafter. While this isn't confirmed, there has been some speculation that Lopez's elbow might have been a factor. The Phillies will now have to search for a set-up man elsewhere.
