The Houston Astros have picked up another high-profile piece for their high-profile rebuilding project.

He'll have to graduate from high school before he starts pitching in, though.

Picking at the No. 1 spot for the third straight year, the Astros selected Brady Aiken, a 17-year-old lefthanded pitcher, with the top overall choice in Thursday night's first round of the MLB amateur player draft.

Aiken, who will turn 18 in August, stands 6-foot-4, weighs 205 pounds and attended Cathedral Catholic High School in San Diego. It's said he already commands a full repertoire of pitches with a fastball that's already topping out in the high-90s.
