shot lead at the halway point of the Scandinavian Masters after shooting a 5-under 67 in the second round Friday. Choi mixed six birdies and an eagle with three bogeys to reach a 9-under total of 135, one stroke ahead of Richard Johnson of Sweden, who carded a 66. British Open champion Louis Oosthuizen was one of the overnight leaders but he slipped to third after a round of 70, leaving him two strokes behind Choi and level with Rafa Echenique of Argentina. Teeing off early in windy conditions at Bro Hof Slott, Oosthuizen had a double bogey at the 150-yard, par-3 17th after landing in the water. The South African collected three birdies and another bogey on his first nine holes, for a par 36, which was four shots off his performance Thursday. Choi had an impressive start with an eagle on the 15th, as well as birdies at the 13th, 16th and 17th, for a 5-under 31 on his first nine. Johnson had a bogey-free round in front of his home crowd put him 8 under after 36 holes. Dustin Johnson of the United States, who was tied with Richard Green and Oosthuizen after the first round, lost ground on the leaders after a round of 73, putting him at 4 under. Green was three shots off the lead after a 71, including consecutive bogeys at holes 4 and 5. Pavin, Langer share lead American Ryder Cup captain Corey Pavin shot a second straight 2-under 69 Friday to share the second-round lead with Bernhard Langer of Germany at the Senior British Open. Pavin and Langer (71) have 4-under totals of 138 to sit one shot clear of a quartet that includes Ian Woosnam (67) and Jay Haas (69). Pavin was among the early starters and looked set to take a commanding lead before finishing with a double bogey 6 at the 18th after hitting his second shot out of bounds. Langer had to deal with a biting cold wind later in the day but also got to 6 under before bogeys on two of the par-3 holes. At the short 13th, his tee shot landed in a deep pot bunker, and he then missed the green at the 16th with a 5-iron and was unable to get up and down. Langer has 10 wins in three years on the Champions Tour but is still looking for his first victory in a senior major. Americans Dan Forsman (71) and Larry Mize (70) were also tied for second. Tom Watson, who missed the cut in his last British Open appearance at St. Andrews last week, had no problem making sure will be around for the weekend this time. He sank a 15-foot birdie putt on the last green for a level-par 71 to remain at 3 over. However, Bob Charles (70) of New Zealand – the first left-hander to win the British Open in 1963 – bid farewell after shooting a 78 to miss the cut. Miyazato ahead Japan's Mika Miyazato defied atrocious weather and two delays to post a second round of 67 to take the halfway lead in the Evian Masters in France Friday. But Miyazato's thunder was almost stolen by local girl Gwladys Nocera who attracted most of the attention as she also shot 67 and surged into second place. It could have been even better for the 35-year-old who uses the course as a regular practice venue. She birdied the short 17th from 15 feet to join Miyazato on nine under par, but hit a tree and dropped a shot at the long 18th. In fact, she holed a good putt from 12 feet for bogey to finish on eight under. Nocera, a three-time Solheim Cup player and the European No. 1 player two years ago, has struggled in her five previous appearances at Evian. Her best performance was a tie for 41st and she has suffered the embarrassment of missing the cut on her past two attempts.
