Robert-Jan Derksen maintained a two-stroke lead with with a 3-over-par 75 after battling conditions he described as “unfair and unplayable” in the third round of the Ballantine's Championship on Saturday. Derksen, who also led by two strokes after the second round, had a 54-hole total of 6-under 210 on the Pinx Golf Club course. “It was very tough,” Derksen said. “I think it was unfair and unplayable. It was unplayable and the only thing you can do is to just do your best,” he said. But a joint statement from the European Tour and Asian Tour said while they were aware there was concern from a number of players, they were only aware of one serious instance of a player being disadvantaged. The leading 10 players all shot over-par rounds Saturday. Spain's Pablo Martin (74) was in second at 4-under 212, followed by three players tied for third, four off the lead - South Koreans Kang Wook-soon (77) and Kang Kyung-nam (75) and Thongchai Jaidee of Thailand. Ernie Els was in a five-way tie for sixth after a 73, five shots back of Derksen. England's Lee Westwood shot 76 and was 10 strokes back, while American Fred Couples shot 81 and was at 10-over 226. Kelly seizes lead In Louisiana, Jerry Kelly, who is seeking to end a seven-year victory drought, fired a six-under 66 to take a one-stroke lead after the second round of the Zurich Classic of New Orleans on Friday. Kelly rolled in seven birdies and had one bogey as he moved to 10-under 134. He had a one-shot lead on fellow Americans Troy Matteson (64) and Charley Hoffman (66) while first-round leader Charlie Wi of South Korea shot two-under 70 and was tied with five others for third. England's Ian Poulter and Rory Sabbatini of South Africa also continued to play well. They were three shots adrift of Kelly after Poulter shot a 66 Friday and Sabbatini a 67. Ochoa leads by three In Mexico, defending champion Lorena Ochoa fired her second straight eight-under-par 65 on Friday to take a three-shot lead midway through the USLPGA Tour's Corona Championship. The world number one from Mexico notched her second bogey-free effort in as many days for a halfway total of 130 that put her in good position to defend the title she won here last year. Norway's Suzann Pettersen posted a 64 for 133. Taiwan's Yani Tseng, ranked number two in the world, fired a 66 and South Korea's Na Yeon Choi a 69 to lie five strokes back on 11-under 135. It was a further stroke back to American Kristy McPherson (68). American Michelle Wie (71) was on nine-under 137, along with Sarah Lee (70), Karrie Webb (67), Irene Cho (67) and Brittany Lang (68). American Brittany Lincicome followed her opening 75 with a 73 to miss the cut.
