"He's a switch-hitting outfielder, he's got some height to him," D-backs GM Dave Stewart said. "Right now he's a little skinny. He's got a lot of raw talent and ability. He's an above-average runner, he's got above-average tools, he's just real young."
MLB.com ranks Reyes as the 27th-best prospect in the D-backs' system.
The D-backs own the No. 1 overall pick in the Draft by virtue of having the worst record in baseball last year.
After evaluating the talent level in this year's Draft, the D-backs were willing to trade their Competitive Balance Round pick.
"Quite frankly, the Draft right now looks like it's going to be so-so at best," Stewart said. "It may be good, it may not be, but right now I think if you talk to anybody about the Draft, I don't think anybody is turning flips. There's no clear No. 1 in the Draft, and after the No. 1 pick, who knows how it's going to be?"
