There's nothing Carlos Correa does publicly that would lead you to believe he's 19 years old. He stands a solid 6-foot-4 with broad shoulders that are reminiscent of a young Alex Rodriguez. He makes eye contact, has an easygoing demeanor and speaks eloquently in English, though it's not his native language.

Even if you know nothing about Correa, the former No. 1 overall pick in the First-Year Player Draft, you can certainly understand why the Astros were so smitten with him. And when you watch him play, it's clear why he's considered Houston's top prospect.

This season figures to be a big one for Correa, the shortstop who is coming to Major League camp for the first time after a bang-up season in the Midwest League as an 18-year-old. He'll be one of the youngest players in a young clubhouse in Kissimmee, Fla., but no one is brimming with more potential.

"I'm really excited about this year," Correa said Saturday at FanFest. "I'm excited to go out there in big league camp and show them what I can do in the field and do a great job up there. It will be a fun experience."

Correa spent the 2013 season as the second-youngest player in the Midwest League and still led the league in OPS (.872) while finishing second in on-base percentage (.405) and third in batting average (.320) in his first full season in professional baseball. He also had nine home runs and 86 RBIs.

He's likely to begin 2014 at Class A Advanced Lancaster and could spend half of the season at Double-A Corpus Christi.

"To play a full season of A ball at the age of 18 and have the success he's had is very unusual," Astros general manager Jeff Luhnow said of the first pick in the 2012 Draft. "It suggests a bright future for him. Every decade or so, a really special player gets to the Major Leagues before he turns 21, and I think he has a chance to be that type of player."

Correa has already made strong impressions on the Major League staff after appearing in a handful of Grapefruit League games last year. At 19, he's not going to make the Opening Day roster, but this will probably be the final spring he comes to camp not considered a part of the immediate plans for the Major League club.
