So about 6:15pm Central time Jeff Luhnow tweeted this...
It links to Michael Baumann's really good Grantland article on whether Luhnow/Astros would actually call up Carlos Correa, Mark Appel, Colin Moran, etc.
WELL. Fast forward to this:
Who isn't on that list? Shortstop Carlos Correa. Weird, huh? Now, it could just be a scheduled day off - Correa got the last game of the Tulsa series off on April 21 and then there was a travel day on April 22. So if the Astros are working to give Correa a day off every week or so, then this might be it.
