Belgian Nicolas Colsaerts came from five behind and shared the lead in the Nordea Scandinavian Masters with eight holes to go at Bro Hof Slott near Stockholm.
After torrential overnight rain delayed the start by four and a half hours Colsaerts went to the turn in 32 to catch Swede Richard S Johnson on nine under par.
Johnson had been joint overnight leader with K J Choi, but the Korean went out of bounds with his opening drive and managed only an outward 39.
So did Open Championship winner Louis Oosthuizen after resuming just one behind and it was Argentina's Rafa Echenique who was breathing down the neck of the two leaders.
Colsaerts failed to birdie either of the first two par fives on the back nine and when Echenique made a nine footer on the 548 yard 12th he became part of a three-way tie on nine under. New Zealander Mark Brown was only one behind after birdies at the 11th and 12th.
While Colsaerts fell back with bogeys on the 14th and 15th first Echenique and then Johnson birdied the 13th to go two clear of the field.
Echenique had birdied the first four par fives and had a chance to make it five out of five, but missing from four feet opened the door to Johnson in the group behind.
Johnson took the chance on offer at the 15th, chipping to four feet and making the putt.
Echenique almost found the water on the short 17th, but his ball stayed on the bank and as he saved par from seven feet Johnson missed the green at the 16th, chipped six feet past and missed. They were back together on ten under as a result.
