Agencies NEWTOWN SQUARE, Pennsylvania – K.J. Choi of South Korea birdied five of his last six holes for a six-under par 64 that tied the course record and gave him a two-shot lead after two rounds of the AT&T National Friday. Choi capped his sizzling round with a one-foot tap-in for birdie at the 605-yard, par-five ninth after his approach shot nearly fell into the cup. He stood at seven-under-par 133. Americans Justin Leonard (67), Chris Riley (66) and Bo Van Pelt (66), and Charlie Wi (66) of South Korea shared second place at five-under-par 135. Four players were tied on 136, including American Jeff Overton, who fired a 65 to get back into contention. Choi, who missed the cut in his last start at the US Open two weeks ago, caught fire on Aronimink's front nine after beginning his morning round at the 10th. His final birdie matched the 64 shot by 2010 champion Justin Rose of Britain in the second round last year. Choi won the inaugural AT&T National when it was played at Congressional in Bethesda, Maryland, in 2007. First round co-leader Adam Scott of Australia followed his opening 66 with a one-over-par 71 and was at three-under 137, a total he shared with American Rickie Fowler. American Hunter Haas, who also had a 66 Thursday, posted a 74 in the second round and faded out of contention. Two share lead Mark Foster of England shot a 3-under 68 to share a one-stroke lead with compatriot James Morrison after the third round at the French Open Saturday. Foster made up for two bogeys with five birdies for a 9-under total of 204. Overnight leader Morrison had a two-shot lead on the back nine but a double bogey on the penultimate hole and a bogey on the last saw him close with a 1-over 72. Richie Ramsay of Scotland climbed to third by carding a 68 despite bogeying his last two holes. Martin Kaymer of Germany and Frenchman Thomas Levet remained in contention, tied for fourth place, three strokes off the pace. The round did not start well for Morrison, who pulled his tee shot into the water for a double bogey on the second hole and surrendered the lead to Richard Green of Australia. But Morrison recovered by converting a short birdie putt on the sixth to join Green at the top of the leaderboard. Morrison still led by a stroke on the last hole, but missed a 3.5-meter (12 foot) par putt to drop back into a tie with Foster for the top spot. Foster started the round in third place, four strokes off the pace. He made three birdies in five holes to claim a share of the lead with Green and Morrison at 9-under, but bogeyed the eighth hole to slip back to third, one stroke off the lead. Green closed with a 76 to drop into a tie for seventh place with Bradley Dredge of Wales at 4-under overall, one stroke behind Thorbjorn Olesen of Denmark in sixth place. __
