FORT WORTH, Texas — Kelly Kraft, Derek Fathauer and PGA Tour rookie J.T. Poston all shot 5-under 65 on Thursday to share the lead after the first round at the Colonial.

Jon Rahm, Scott Brown and Graeme McDowell followed at 66.

Two-time Colonial champions Phil Mickelson and Zach Johnson both birdied their last three holes and were among six players with rounds of 67.

Defending champion Jordan Spieth, coming off consecutive missed cuts, was tied for 34th after an even-par 70 with six birdies, four bogeys and a double bogey.

Only 33 of the 121 players finished under par.

Kraft and McDowell had the only bogey-free rounds. Brown had the lead outright at 6 under before a double bogey on his last hole.

LPGA: Stacy Lewis shot a 7-under 65 to share the first-round lead in the Volvik Championship at Ann Arbor, Michigan.

Lewis was tied with an unexpected challenger in Wei-Ling Hsu, the Taiwanese player who has only one top-10 finish on the LPGA Tour.

Hsu eagled two of her first five holes and was 6 under through six. She and Lewis ended up a stroke ahead of Nelly Korda.

Lewis, a former world No. 1, is winless in 72 events since June 2014. She has 11 LPGA Tour victories and 25 second-place finishes – 12 since her last win.

CHAMPIONS: Bernhard Langer held a two-shot lead at Sterling, Virginia, as he aims for his record ninth senior major at the Senior PGA Championship.

Langer shot a 7-under 65 in the morning and the lead held up as thunderstorms halted play in the afternoon with half the 156-man field still on the course.

Langer, a 59-year-old German, could break Jack Nicklaus’ record of eight senior majors with a win. He tied Nicklaus last week with a five-shot victory at the Regions Tradition. He would also become the first player to win all five of the current senior majors.

Langer finished off his round with a tap-in eagle at the par-5 18th.

EUROPEAN: British Open champion Henrik Stenson shot a bogey-free, 4-under 68 to lie two strokes off the lead held by Swedish compatriot Johan Carlsson after the first round of the BMW PGA Championship at Virginia Water, England.

All four of Stenson’s birdies came on the back nine on new greens rolled out for the signature event on the European Tour. They appeared to meet with widespread approval, especially from Carlsson, whose hot run came on the front nine where he reached the turn in 30 shots, thanks to five birdies.

“The greens are so good. I love this golf course right now,” said Carlsson, who had eight birdies in his 66. “I think it has become so much better.”

Ernie Els was behind the latest changes to the West Course following criticism of his original redesign in 2010. The renovation program started eight days after Chris Wood’s victory last year, with all 18 greens stripped of their old turf and reseeded.
