With the 1st pick in the 21st Round (639th overall), the Astros select Marc Wik, a 5'11" 195lb lefty CF out of Chabot College (CA).
Wik was drafted by the Orioles in the 20th Round last year.
He likely fell due to injury, as he tweeted yesterday:
I wonder what round I would have went in if I was healthy? #dissapointed #unhappy
But it looks like in 30 games this season, he was hitting .358 with 22 stolen bases.
