Bud Norris has been scratched from his start by the Astros tonight, and Jeff Passan just relayed this on Twitter:
Sources: Bud Norris very likely to be dealt today, and Pittsburgh could be landing spot. Package built around Tyler Glasnow makes sense.

It's not clear to me whether or not Passan has knowledge of a potential trade, or if he's just spitballing based on a look at the Pirates' system and what the Astros might be interested in. He says the Pirates won't give up Polanco (duh), but that "Houston does like Glasnow." Frankly, you'd be pretty stupid not to like Glasnow at this point, because 6'7" righties that strike out 128 hitters in 92 1/3 innings at the age of 19 in full-season ball are pretty rare.
Anyway, it seems clear that there's no deal that's imminent, so for now let's not try to freak out and just see how things play out this afternoon.
