Unlike in recent seasons, there is no clear-cut choice for the first overall selection in this June's First-Year Player Draft. Stanford right-hander Mark Appel, Georgia high school outfielder Byron Buxton, Louisiana State right-hander Kevin Gausman, Texas A&M right-hander Michael Wacha, San Francisco right-hander Kyle Zimmer and Florida catcher Mike Zunino are all considered candidates. The Astros own the No. 1 pick.
