Overnight leader Peter Uihlein of the United States shot a 4-under 68 and was tied for the second-round lead with Brett Rumford at the Perth International, with former British Open champion Louis Oosthuizen a stroke behind Friday. Uihlein, who birdied his final two holes after starting on the back nine, and Rumford, who carded 65, had 36-hole totals of 11-under 133 at Lake Karrinyup Country Club. Oosthuizen, the 2010 British Open champion playing for the first time in Australia, had a 64 for the low round of the day after an opening 70. Oosthuizen was on track to join Rumford and Uihlein at the top of the leaderboard, but missed a short birdie putt on the final hole. "I just over-read it," Oosthuizen said. "It was the first real putt I had in the shadows today. I took my glasses off, and I misread it a little bit. It's not going to bother me though." European Ryder Cup player Victor Dubuisson of France posted a 1-under 71 but was still 4 over overall and missed the cut in the European Tour and Australasian PGA event. Australian Marcus Fraser, who won the Maybank Championship in Malaysia last week, was at 2 under with veteran Peter Senior. Other notables beside Dubuisson to miss the cut included defending champion Thorbjorn Olesen (5 over) and 2013 winner Jin Jeong (4 over). Larsen, Lennarth in front Nicole Broch Larsen of Denmark and Sweden's Camilla Lennarth took a two-stroke, second-round lead Friday at the Australian Ladies Masters in Australia. Lennarth shot her second consecutive 5-under 68 while Broch Larsen, thanks to a chip-in eagle on the final hole, carded a 69 for two-round totals of 10-under 136 at Royal Pines. Lennarth, starting on the 10th hole, had four birdies on her final nine, including the eighth and ninth. Broch Larsen said she was confident of making eagle or birdie at 18 but her five-iron approach on the 423-meter, par-5 hole missed the green to the right, finishing in a deep swale. Brooke Henderson of Canada, who led with Larsen after the first round with 67s, was tied for third after a 71 with South Korean Jiyai Shin (70). So Young Lee of South Korea and England's Holly Clyburn, who each shots 69s, were tied for fifth. Lennarth, 27, finished third behind Cheyenne Woods in 2014 at Royal Pines and was tied for sixth last year behind champion Su Oh. Marion Ricordeau of France, the other first-round leader, shot 77 to drop eight strokes off the pace in the joint Ladies European Tour and Australian Ladies event. Oh shot 75 and was at even par. Woods shot 81 Friday after an opening 75 and missed the cut. — Agencies
