GREENSBORO, N.C. — Si Woo Kim had a productive week at the Wyndham Championship. He claimed one tournament record, a share of another – and, most importantly, his first PGA Tour trophy.

The 21-year-old South Korean player closed with a 3-under 67 for a five-stroke victory Sunday. He had a 21-under 259 total at Sedgefield, tying the event 72-hole record set eight years ago by Carl Pettersson.

Kim matched Pettersson by sinking an uphill 14-foot birdie putt on the final hole, then said through an interpreter that he “never expected any course record.”

Kim set a tournament record with a 60 in the second round. He earned 500 FedEx Cup points and $1,008,000 in prize money in the regular-season finale.

Luke Donald was second at 16 under after a 67.

EUROPEAN TOUR: Paul Peterson shot a 5-under 67 to win the Czech Masters by one stroke and earn the 398th-ranked American his first victory on the European Tour, in Vysoky Ujezd, Czech Republic.

In a close contest with defending champion Thomas Pieters of Belgium, Peterson took the decisive lead when he birdied the par-3 16th hole for a total 15-under 273 at the Albatross Golf Resort near Prague.

U.S. AMATEUR: Curtis Luck won eight consecutive holes shortly after the midway point of the U.S. Amateur final, and the Australian beat Brad Dalke 6 and 4 to become the third international champion in four years, in Bloomfield Hills, Michigan.
