Si Woo Kim gets first PGA Tour win at Wyndham Championship

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 three-under 67 for a five-stroke victory Sunday. He had a 21-under 259 total at Sedgefield in Greensboro, N.C., 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.

Kim became the youngest winner on tour this season, and the second-youngest in tournament history; Seve Ballesteros was 20 when he won here in 1978. Kim also became the eighth player from South Korea to win on the tour — they’ve combined for 18 victories — and the second to do so in Greensboro, joining 2005 winner K.J. Choi.

Luke Donald was second at 16 under after a 67. Hideki Matsuyama and Brandt Snedeker were 15 under, also each shooting 67.

Australian wins the U.S. Amateur title

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.

The 36-hole final on the South Course at Oakland Hills in Bloomfield, Hills, Mich. was all square after 18, and Dalke won the first hole after the break. Luck answered with an eagle on the 20th to square it again, and that was start of an overwhelming eight-hole run that gave him a commanding lead.

The 20-year-old Luck was 7 up with nine holes remaining, and although Dalke won the next two, the Oklahoma sophomore couldn’t close the gap any more. He conceded after missing a putt for par on the 32nd.

Luck joined Matthew Fitzpatrick of England (2013) and Gunn Yang of South Korea (2014) among recent international winners. He’s also only the third Australian-born champion. Nick Flanagan won in 2003 and Walter Travis won it in 1900, 1901 and 1903.

Peterson wins the Czech Masters

American Paul Peterson won the Czech Masters for his first European Tour title, closing with a five-under 67 for a one-stroke victory.

Ranked 398th, Anderson finished at 15-under 273 at the Albatross Golf Resort near Prague. The 28-year-old Anderson played at Oregon State. Defending champion Thomas Pieters of Belgium was second after a 70.
