The top unsigned pick, seventh-rounder Preston Tucker, could still be signed, though. Because he was a senior at the University of Florida, he is subject to a different deadline, a week before the 2013 Draft next June.
The next highest unsigned pick was 11th-round selection Hunter Virant, a pitcher from Camarillo (Calif.) High. Virant was considered a top prospect, but he slipped in the Draft because of a commitment to UCLA.
The Astros also failed to sign 26th-round pick C.J. Hinojosa, a shortstop from Klein Collins High in Spring, Texas; and 39th-round pick Mitchell Traver, a right-hander from Houston Christian High.
The Astros signed 30 of their 41 Draft picks, including the No. 1 overall pick: shortstop Carlos Correa.
