Give U.S. slight edge in Sat. foursomes

SAN FRANCISCO -- As the Day 2 four-ball sessions came to a close here at the Presidents Cup, U.S. captain Fred Couples offered a wish of which he was also in command.

"We don't want to change up the alternate shot pairings at all," he said.

So it shouldn't come as a surprise that three of the five Saturday morning pairings are reprisals from Thursday, as Couples kept the teams of Justin Leonard-Jim Furyk, Tiger Woods-Steve Stricker and Kenny Perry-Zach Johnson intact.

Turns out International captain Greg Norman had the same idea, keeping three of his alternate shot twosomes intact, as Ernie Els-Adam Scott, Robert Allenby-Vijay Singh and Mike Weir-Tim Clark will tee it up together in this format again.

If there is any shocking revelation regarding the foursomes matches, perhaps it is that the third session at Harding Park Golf Course will be without three major champions and one of the game's up-and-coming stars, as Couples elected to sit reigning U.S. Open champ Lucas Glover and young stud Anthony Kim and Norman will bench Masters winner Angel Cabrera and Geoff Ogilvy, the No. 10 player in the world.

Each will return to the course for Saturday afternoon's four-ball matches, but they'll be relegated to rooting on teammates early in the day. Let's break down exactly what those four will be watching, giving an edge to one team in each match.
