GREENSBORO, N.C. - Joohyung "Tom" Kim announced his arrival on the PGA Tour on Sunday, when the 20-year-old South Korean closed with a 9-under-par 61 for a five-shot victory in the Wyndham Championship, making him the second-youngest winner since World War II on golf's top circuit.

A marathon day because of storm delays turned into a sprint for Kim. He finished the third round in the morning and was two shots behind, then shot 27 on the front nine to leave the rest of the field in his wake as no one came close the rest of the way.

The victory gave Kim instant membership on the PGA Tour, making him eligible for the FedEx Cup playoffs that start Thursday in Memphis at the FedEx St. Jude Championship. He is No.
