The Astros have the first overall pick in major league draft for the second-straight year and Jeff Luhnow has placed emphasis on getting things right.

"How well we do in this Draft as a whole is very important to the organization," Luhnow said. "It's hard to put much weight on any one particular pick, because we all know the failure rate of players is very high and you don't want to hang everything on one player. How we do in terms of bringing in talent and developing talent, that's the most important thing we can do."

Oklahoma right-hander Jonathan Gray is among a handful of players the Astros are considering with the first pick, including Stanford pitcher Mark Appel and college hitters Kris Bryant (San Diego) and Colin Moran (North Carolina).

"We want the guy as an organization we believe is going to create the most Major League value," Luhnow said. "It's as simple as that. It's easy to say that, but hard to define what that means. There's a lot of factors that go into it. Certainly, what they've done in the past is a big part of it, and the scouts are experts and they get paid to evaluate players and predict the future.

"Predicting the future is a risky business, but they're pretty good at it and they're a lot better than most of us would believe. We have to listen to our scouts and trust their opinions. There's a lot of factors that go into it, but at the end of the day, you feel good about your decision, but you're never 100 percent sure."
