Louis Oosthuizen has a chance to make history at the Scandinavian golf Masters near Stockholm.
The South African is one stroke off the lead in outright third going into the final round, and could become the first Open champion to follow up with a win on the European Tour.
New Zealand's Mark Brown is just three shots off the lead in a two-way share of fourth.
South Korea's KJ Choi and home favourite Richard Johnson share the lead at 10 under par.
