England's David Horsey and Scotland's Peter Whiteford share the lead, four shots clear of their nearest rivals, heading into the final round of the Russian Open.

Horsey, who led the opening two rounds, shot a 2-under-par 70 on Saturday to reach 13-under 203 and was joined by Whiteford whose 66 was the best round of the day at a sunny but windy Tseleevo Golf and Polo Club in suburban Moscow.

Horsey is one of just three players in the event ranked inside the world's top-200 and is seeking his third European Tour win, three years after his previous title, while Whiteford is aiming for his first victory in his 181st tour event.

Scotland's Scott Jamieson (69), Italy's Andrea Pavan (64) and Belgium's Thomas Pieters (72) share third place at 9-under.
