The earlier report about Philadelphia and Houston agreeing to a Roy Oswalt trade kind of came out of nowhere, so it's only natural to question its validity. Enter Alyson Footer, who describes herself as the Astros' Senior Director of Social Media:
for what it's worth Berman is never wrong when he goes that far w/ his reporting. He is 100 % or he doesn't go with it.
Berman, of course, being the man behind the report. Over the offseason, Berman was the first to report the Brandon Lyon signing with Houston, so this certainly seems legitimate. All that's left to do is await an answer from Roy Oswalt himself on what he's going to decide.
