Apparently, it's getting more serious. MASN's Byron Kerr, in a story about some other catcher, referred to the Astros:
The Houston Astros were looking at Jesus Flores so Norris was limited to one at bat yesterday, but thinks he might be back in the lineup some time later in the week.
It's a throw-away line for Nationals fans, but it's a pretty decent indication that the Astros are thinking about moving on Flores.
