Ken Rosenthal is tweeting (https://twitter.com/ken_rosenthal/status/494858515308367872) that the Astros have been "very very busy" with calls regarding Jarred Cosart, but have taken Dallas Keuchel off the market.
Update: The Orioles are NOT in on Cosart (Rosenthal), but Rangers and Marlins are.
Update: Cosart is scheduled to pitch tonight, and word from JJO is that nobody has been flown from OKC to Houston, in case he is traded.
