This is from Mark Zuckerman's online chat today. 
Mark Zuckerman:
As a matter of fact, Patterson was back at RFK for the first time yesterday. Sadly, he left the building before the clubhouse opened to the media at 3:30, but I'm told he played catch and is generally optimistic about his situation. I'm hoping he's here today and talks with us, because I'm dying to know more about his whole experience in Toronto and where he thinks he goes from here. And yes, he definitely needs to try to pitch again this season if he wants to convince the Nats to keep him around in 2008.
Sounds like most of us are on the same page as Zuckerman. Glad he's back - now get out there and pitch, JP. You have a roster spot - use it or lose it.
