The Giants had six of the first 51 picks and used five of them on high school players in baseball's first-year player draft, including left-hander Madison Bumgarner with the No.10 selection and right-hander Tim Alderson with the 22nd choice.
They used the 29th overall pick, their last of the first round, to grab athletic high school outfielder Wendell Fairley. And in the supplemental round, they took two high school infielders second baseman Nick Noonan (32nd overall) and shortstop Charlie Culberson (51).
The only college player they took high was Jackson Williams, a catcher and defensive specialist from the University of Oklahoma (43rd pick).
"Not only did we get what we felt were the best people available in each round, but we got talent across the board," Sabean said. "It's a pretty diverse group. Our board was in the right shape and we had guys in the right spots."
Under new terms of the collective bargaining agreement, the Giants must sign their draftees by Aug. 15 or the player returns to next year's draft pool and the Giants will receive an identical pick next June.
Bumgarner, a native of Hudson, N.C., signed a letter-of-intent to play at the University of North Carolina. Alderson, who is from Scottsdale, Ariz., made a commitment to Oregon State.
Fairley, who is from Mississippi, was a standout wide receiver and was recruited by Louisiana State and Florida. He prefers baseball and signed with Southern Mississippi but said he plans to sign and play professionally.
"I'm a Giant now," Fairley said.
The Giants expect to sign all six of their top draftees, including Bumgarner and Alderson the first high school pitchers they took in the first round since they drafted Matt Cain 25th overall in 2002.
