You know that Wilton Lopez has had some injury problems. I know that Wilton Lopez had injury problems. The Phillies know that Wilton Lopez had injury problems.

Is it all that surprising that his health is one of the things holding this potential trade of Lopez to Philadelphia?

#Phillies-#Astros deal will not be complete until Wilton Lopez passes physical. Lopez had an elbow issue in June and Phils checking it out.

The #phillies deal for Wilton Lopez is pending physical. Two players going to Houston.

This Wilton Lopez physical with Philly isn't a slam dunk. Some clubs have been scared off by his medicals in the recent past.

We'll see where this leads, but remember that teams pretty much have control on whether to pass or fail someone on a physical. This is all part of the negotiations, as Ruben Amaro tries to out-ninja Jeff Luhnow. And we all know that can't be done. It's not physically possible.
