...and the entirely expected happened in Astros-land. Meaning, nothing. Is what happened.
Preston Tucker didn't sign, but Jim Callis confirms that he likely still will. Hunter Virant "can't wait to be a [UCLA] Bruin." And... that's it.
Assuming that Tucker (eventually) signs, it will be the second year in a row that Houston has inked all of their picks from the top 10 rounds. They'll end up with 31 of 41 picks signed, after they signed 30 of their top 40 picks last year.
Up next in Draft-land is the confusing-as-heck "Competitive Balance Lottery," giving 13 teams a shot a 6 extra (and tradeable!) picks between the 2nd and 3rd rounds of next year's draft. But the Astros aren't one of those lucky 13, so never mind about all that.
EDIT: And had I posted a moment later, I could have linked to this handy deadline day rundown from Zach Levine.
