Shortstop Carlos Correa, the Houston Astros' No. 1 prospect, underwent arthroscopic surgery to correct a fractured right fibula on Wednesday and will miss the remainder of the minor league season.

The Astros remain hopeful that Correa, who on Tuesday was named to his second consecutive All-Star Futures Game roster, will return from his rehab in time to participate in the Arizona Fall League in October. Correa, 19, will be unable to put weight on his right leg for at least four weeks, after which time he will be restricted to a walking boot.

"Obviously (it's) unfortunate one of our top young players in the game is losing this amount of time but we are optimistic that he's going to return to 100 percent and will be back on the field with us ready to keep doing what he's been doing," Astros general manager Jeff Luhnow said.

Correa was the No. 1 overall pick in the 2012 draft out of Puerto Rico and validated the Astros' selection during his first full season with the organization, posting a sparkling .320/.405/.467 slash line with Class A Quad Cities in 2013. He was in line for a promotion to Double-A Corpus Christi before suffering the injury last Saturday night sliding into third base playing for High Class A Lancaster, where he was hitting .325/.416/.510.

As the No. 7 overall prospect in baseball, Correa has a promising future ahead. This derailment serves as his first professional tribulation.

"He's taking it about as well as any young man can take it," Luhnow said of Correa. "It's the first time he's been injured. He did a lot of research. We talked to several doctors, his parents are here supporting him, and he went into this with a very good attitude. He's determined to work as hard as he can on his rehab and get back as soon as he can.

"Obviously we're probably going to have to slow him down a little bit because we want him to heal as well as he can. With a player like that he's always going to want to push the envelope so we'll have to figure that out."
