Sweden's Per-Ulrik Johansson will take a four-shot lead into the final round of the Russian Open in Moscow.

He carded a third-round 67 for an 18-under total of 198, maintaining the lead forged by a brilliant 62 yesterday.

Holland's Robert-Jan Derksen returned a 65 to move into second place on 14 under, one ahead of Canada-based Scot Alan McLean.

Ireland's Gary Murphy (70) and England's Adam Gee share fourth place a stroke further back.

Johansson played on the victorious European Ryder Cup teams at Oak Hill and Valderrama in 1995 and 1997, but has not won on the European Tour for a decade.

The 40-year-old showed signs of his old form when finishing 15th in the European Open earlier this season and carded five birdies and an eagle today to maintain his grip on the tournament.

Starting from the 10th as tournament officials made a "U-draw" to try to get back on schedule following the various rain delays, Johansson picked up shots at the 11th, 12th and 17th.

A double bogey on the 18th gave the chasing pack a glimmer of hope, but a birdie on the first was quickly followed by an eagle on the second and another birdie on the fifth for an inward half of 32.

Murphy had earlier moved to within four shots of the lead when he finally completed his second round this morning.

Murphy managed only five holes due to rain interruptions yesterday and sat second, six shots behind Johansson's overnight lead.

Resuming this morning, however, the 34-year-old turned in a sterling inward half with birdies at the 11th, 12th and 15th for a round of 68 and nine-under total of 135.
