South Korea will form the backbone of the International team¡¯s hopes of upsetting the United States at the Presidents Cup with a record four players set to tee off on Thursday at the Quail Hollow Club.

Im Sung-jae, Kim Si-woo, Tom Kim and K.H. Lee make up one-third of Trevor Immelman¡¯s 12-man squad and will be counted on to produce points if the Internationals are to challenge the heavily favored Americans.

Two of those South Korean rookies, 20-year-old dynamo Tom Kim, the youngest player in this year¡¯s event, and Lee will join forces to take on the U.S. duo of Cameron Young and Collin Morikawa in Thursday¡¯s opening foursomes.
