Yang takes 3-stroke lead at LPGA event in Malaysia

Amy Yang holed a pitching wedge for eagle on the par-4 11th hole and stretched her lead to three strokes Friday in the hot, humid and stormy Sime Darby LPGA Malaysia at Kuala Lumpur.

The 27-year-old South Korean player had a 2-under 69 at TPC Kuala Lumpur, a day after shooting 63 to miss her own course record by a stroke.

PGA: Hideki Matsuyama made nine birdies in suddenly chilly conditions for a 7-under 65 that gave him a three-shot lead going into the weekend at the HSBC Champions in Shanghai.

Neither the rain in the opening round nor the bone-chilling cold on Friday seem to matter to the Japanese star, who has made 19 birdies over 36 holes at Sheshan International that got the attention of the players chasing him.

• Grayson Murray shot a 7-under 65 to take a two-shot lead in the Sanderson Farms Championship at Jackson, Mississippi.

Murray, a 23-year-old rookie playing in his third career PGA Tour event, bogeyed his first hole at No. 10, but then made eight birdies – the last on the final hole.

CHAMPIONS TOUR: Fred Couples shot a 4-under 68 in his first competitive round in eight months while Bernhard Langer withdrew after his left knee acted up in the PowerShares QQQ Championship at Thousand Oaks, California.

OLYMPICS

RIO GAMES: The World Anti-Doping Agency detailed serious failings of doping control management at the Rio de Janeiro Olympics, saying the system was only saved from collapsing by the “enormous resourcefulness and goodwill” of some key staff.

In a 55-page report from its independent observer team led by British lawyer Jonathan Taylor, WADA said the logistical issues which put a strain on the testing process were “foreseeable and entirely avoidable” during the games in August.

COLLEGES

FOOTBALL: An outside investigation of the Baylor University sexual violence scandal found 17 women who had reported sexual or domestic assaults involving 19 Baylor University athletes since 2011, university regents have told The Wall Street Journal.

The scandal involved 17 women who reported domestic violence or sexual assaults that involved 19 players since 2011. Four were alleged gang rapes, according to Baylor regents.

In at least one of the cases, regents said, Briles knew about the complaint but didn’t alert police or the proper Baylor officials.
