(AP Photo/Reed Saxon) The Associated Press Feb. 25, 2013 Comments LOS ANGELES — Bill Haas had another bogey-free round at Riviera while shooting a 7-under 64 — the best round of the day by three shots — to take a three-stroke lead into the final day of the Northern Trust Open. On a warm day off Sunset Boulevard that made greens even faster, Haas turned in a remarkable score. The key was a seven-hole stretch in the middle of his round that he played in 6-under par, including a chip-in for eagle on the par-4 10th. He was at 12-under 201 and will try to become the eighth back-to-back winner in the 76-year history of this tournament. U.S. Open champion Webb Simpson and former Masters champion Charl Schwartzel each had a 68. They were three behind, along with John Merrick (70). Champions Langer has 3-shot lead after TWO rounds: In Naples, Fla., Bernhard Langer shot a 2-under 70 to take a three-shot lead after the second round of the Champions Tour’s ACE Group Classic on Saturday. Langer, who had a 10-under 62 in the first round, picked up where he left off with a birdie on his first hole. He made 11 straight pars after that, birdied No. 13, and had a par on the last five holes in windy conditions. He is at 12-under 132. Taiwan’s Chien Soon Lu and Tom Pernice Jr., who was runner-up last week in Boca Raton, Fla., are tied for second at 9-under 135. Lu double bogeyed the first hole, then birdied seven of the next 10. He bogeyed No. 18. Pernice had four birdies and a bogey. He birdied two of his last six holes. The wind picked up just before the leaders teed off and only got stronger as the day went on, gusting to 30 mph. The 55-year-old Langer won this event in 2011 and was runner-up last year. Mark O’Meara was next at 8 under. Mark Wiebe, Jay Don Blake and John Huston are another stroke back. LPGA Shin, Ko share lead at Royal Canberra: In Canberra, Australia, Jiyai Shin of South Korea and 15-year-old amateur Lydia Ko both shot 3-under 70 on Saturday to surge six shots clear of the field heading into the final day of the Women’s Australian Open. Born in South Korea and based in New Zealand, Ko jumped to an early lead at Royal Canberra with birdies on the 2nd, 4th and 6th holes. She allowed Shin to regain a share of the lead with bogeys on No. 12 and 14 before making another birdie on the final hole to finish the day at 17-under 202. Shin, a two-time British Open winner, kept pace by making an eagle out of the green-side bunker on the par-5 6th. But she squandered a chance at the outright lead with a bogey on the next-to-last hole. Beatriz Recari of Spain was in third place after a 71.
