Captains Fred Couples and Greg Norman announced their picks for the 2009 Presidents Cup on Tuesday.

As expected, Couples chose U.S. Open champion Lucas Glover and Hunter Mahan for the U.S. team. Greg Norman made a more surprising choice, going with fellow Australian Adam Scott, who has missed the cut in 10 of the 18 tournaments he's played in this year and has only one top 10 finish. Norman's second choice was Japan's young phemon Ryo Ishikawa.

"Maybe somewhat unexpected. Obviously it's been a tough year," Scott said. "But I really am humbled. I feel like I can contribute points and contribute in the team room, as well."

Norman backed up his Scott selection. "When you look back a year ago, Adam was the No. 3 player in the world. So everybody goes through a slump," Norman said. "At the end of the day, he's got the playing skills, and as Adam said, the team camaraderie, what he can bring to the locker room, the support he gives to the other players, the connection and the experience that he's had playing on the Presidents Cup team. He was really a logical choice."

What gave 17-year-old Ishikawa the edge? "Enthusiasm," Norman said. Citing Ishikawa's credentials, ability to stand up to Tiger and experience dealing with crowds of media, the International captain said, "You've got to have faith in that ability, and I have a lot of faith in him."

Glover played on the 2007 U.S. Presidents Cup team, which won by five points. Mahan was part of the successful 2008 U.S. Ryder Cup team.

Couples struggled with his picks, also considering players like Dustin Johnson and Brian Gay, but in the end went with his gut. "For Hunter Mahan and Lucas, I think it's a no-brainer, I really do," he said. "I chose the two guys, and that's the toughest thing I'll have to do the whole time, and hopefully they'll go to San Francisco and play well."

The rest of the U.S. Team consists of: Tiger Woods, Phil Mickelson, Steve Stricker, Kenny Perry, Zach Johnson, Stewart Cink, Sean O'Hair, Jim Furyk, Anthony Kim and Justin Leonard.

The rest of the International Team is made up of: Geoff Ogilvy, Vijay Singh, Camilo Villegas, Retief Goosen, Ernie Els, Angel Cabrera, Mike Weir, Robert Allenby, Y.E. Yang and Tim Clark.

The Presidents Cup will be played on Oct. 8-11 at Harding Park in San Francisco.
