Sweden: A closing bogey denied Louis Oosthuizen a share of the Scandinavian Masters third round lead on Saturday.
Last week`s British Open champion, though, is still looking for back-to-back successes after a two-under-par 70 left him a stroke behind front-runners KJ Choi and Richard Johnson.
A 70 by Swede Johnson enabled him to tie on 10-under 206 with South Korean Choi who posted a 71.
As the field at Bro Hof Slott had to battle strong winds and then latterly rain, it looked as though Oosthuizen had done enough to repeat his feat of the week before -- lead going into the final round.
However, the 27-year-old South African found a bunker on 18 and could not get up and down for par.
"It was disappointing to do that," Oosthuizen told reporters, "because it was one of only two really bad shots I played all day and both cost me bogeys."
"In fact it was a bit disappointing all round because I could easily have been 12 or 13 under tonight."
Oosthuizen showed his new-found confidence by making a birdie on the long 13th despite driving into a lake, holing an 18-foot putt.
"That`s the thing that has changed with me," he added, "the way I handle myself on the course now. I`m determined to win tomorrow."
Choi was only able to scramble par on the 13th after whipping off his shoes and socks to play from the water`s edge in bare feet.
His par kept the 40-year-old world number 45 on course to add a second European Tour title to his seven U.S. PGA wins.
"My ball control was good," said Choi, "because the weather was pretty bad. It seemed like we had all four seasons in one day."
Choi will have to endure another day with the home crowd urging on playing partner Johnson.
The Swede, on a brief visit to Europe from the U.S. PGA Tour, said he was not feeling any pressure to claim his first European victory because of the huge home support.
"I`m more excited by the thought of tomorrow and I`m not really nervous about it," Johnson said. "I hit some clutch shots today to stay up there."
New Zealand`s Mark Brown came through the field with a 67 to lie joint fourth with Argentine Rafa Echenique (72).
