It's the third and final day of the draft.
With the new rules of the draft, the third day may actually have a little more excitement since there is likely to be a few high end high school prospects drafted at some point. But, that will be balanced out by several players drafted as roster fillers for the short-season leagues.
I would expect a sign ability risk to be selected fairly early today as the Astros are unlikely to know just how much room they'll have under their cap. They will likely grab a guy that they have a decent idea of how much it will take to sign him and feel there's a possibility they have enough room to sign him.
