LPGA Tour

American Danielle Kang shot an 8-under 64 to take a 4-stroke lead at the halfway stage of the Women’s World Championship in Singapore.

Kang, who won last year’s Women’s PGA Championship for her first major title, equaled the course record at the Sentosa Golf Club to lead the LPGA tournament at 12-under 132.

“Never too bad to tie a course record,” Kang said. “That’s interesting to hear. I like that.”

Nelly Korda, whose sister Jessica won the LPGA Tour event in Thailand last week, had a 66 to be tied for second with fellow American Alex Marina (67) while Minjee Lee (66), Cristie Kerr (67) and Chella Choi (69) were a further stroke back at 7 under.

European Tour

George Coetzee shot a second-round 64 on the course he grew up playing on to lead the Tshwane Open by 1 shot at the midway mark in Pretoria, South Africa.

Coetzee made six birdies on a rampant back nine and seven overall to go to 11 under overall, jump six places up the leaderboard, and move ahead of Felipe Aguilar (67) and Mikko Korhonen (64).

Coetzee, a native of Pretoria and once a regular at the Pretoria Country Club, is seeking a fourth European Tour title and his second at the Tshwane Open after winning in 2015.

He put himself in a strong position with four straight birdies over Nos. 12-15 and two more on 17 and 18 in his 7-under round.

Chile’s Aguilar had an eagle, four birdies and two bogeys. Like Coetzee, Finland’s Korhonen also finished strong with five birdies in his last seven. Aguilar and Korhonen were 10 under.

There’s a group of four players 3 shots behind them.

Danny Willett, the 2016 U.S. Masters champion, improved his chances with a second-round, 3-under 68 to go to 4 under and ensure he made the cut.

Champions Tour

Scott Dunlap and Tommy Tolles topped the Cologuard Classic leaderboard at 8-under 65, with Steve Stricker a stroke back in Tucson, Ariz.

Dunlap closed his bogey-free round on Omni Tucson National’s Catalina Course with birdies on par-5 eighth and par-4 ninth. Tolles, playing in the last group off the first tee, birdied the par-4 18th for a share of the lead. He also had a bogey-free day.

University of Illinois coach Mike Small matched Stricker at 66.

Gene Sauers opened with a 67, and Bernhard Langer, Billy Mayfair and Woody Austin shot 68. Langer birdied three of the last four holes. The 60-year-old German star won seven times last season, three of the victories in majors.

Defending champ Tom Lehman, playing alongside Stricker, had a 71.
