This was the first playing of this event and featured four players per team, each of whom was under 30 years of age. The teams tied at 2-2 in the team score portion, and the U.S. squad came out victorious in a playoff.
The United States team included Campbell, Zach Johnson, Hank Kuehne and Campbell's Ryder Cup teammate Chris Riley. The U.S. group was captained by CBS commentator Gary McCord.
The International team, captained by McCord's co-worker and former European Ryder Cupper David Feherty, featured Kevin Na and three Ryder Cuppers - Paul Casey, Ian Poulter and David Howell.
Campbell's 66 was matched by Howell, but Campbell defeated Howell in a playoff to take the individual crown.
The teams tied at 4-under-par 276 in stroke-play competition. For the U.S., along with Campbell's 66, Riley, Johnson and Kuehne each posted even-par rounds of 70. The International squad saw Howell also shoot 66, while Poulter carded a 68, Na posted a 70 and Casey had the high score of the day with a 72.
