SECAUCUS, N.J. (AP) -- The Houston Astros had the No. 1 pick again, and this time, they took a pitcher polished beyond his years.
California high school left-hander Brady Aiken was the first selection in the Major League Baseball draft Thursday night.
"It's the most advanced high school pitcher I've ever seen in my entire career," Astros general manager Jeff Luhnow said. "He has command like I've never seen before of his stuff."
The 17-year-old from San Diego's Cathedral Catholic High School is just the third prep pitcher to be selected first overall, joining fellow lefties Brien Taylor (1991, Yankees) and David Clyde (1973, Rangers).
The Miami Marlins made it the first time high school pitchers were the top two picks in the draft when they selected Tyler Kolek, a hard-throwing right-hander from Shepherd High School in Texas.
Twenty pitchers were taken in the first round, tying the draft record set in 2001.
The Astros are the first team to select first in three consecutive drafts, having picked shortstop Carlos Correa in 2012 and right-hander Mark Appel last year. Aiken is in line to receive a huge contract. The allotted slot bonus for the top pick is nearly $8 million.
Aiken is also the first high school lefty to be drafted in the first five picks since Adam Loewen went fourth overall to Baltimore in 2002. The UCLA recruit, who compared himself to Clayton Kershaw and David Price, has terrific control of a fastball that hits 96-97 mph, a knee-buckling curve and a tough changeup that sits in the low- to mid-80s.
The Chicago White Sox selected North Carolina State left-hander Carlos Rodon with the third overall pick. The 6-3, 235-pound junior was widely regarded as the top college pitcher available and had been in the mix to go No. 1 overall. He followed a dominant sophomore year with a solid but not spectacular junior season.
Indiana slugger Kyle Schwarber went No. 4 overall to the Chicago Cubs as the first position player selected. He is a finalist for the Johnny Bench Award as the best catcher in Division I, although he could move to third base or the outfield in the pros.
Nick Gordon, the son of former big league pitcher Tom Gordon and brother of Dodgers second baseman Dee Gordon, went fifth overall to Minnesota. The Florida high school slick-fielding shortstop was the first of the seven prospects in attendance at MLB Network Studios to have his name called by Commissioner Bud Selig, who is retiring in January and presiding over the draft for the final time.
San Francisco outfielder Bradley Zimmer was taken 21st by Cleveland. His brother, Kyle, was the fifth overall pick by Kansas City in 2012. With the next pick, Detroit took California high school outfielder Derek Hill, whose father Orsino was a first-rounder in January 1982 and is now a scout for the Dodgers.
California high school catcher Alex Jackson went sixth to Seattle, which intends to move him to the outfield.
