Spain's Alejandro Canizares scored a five-under-par 67 on Saturday to take a one-stroke lead into the final round of the Russian Open.
Canizares bogeyed a par-five fifth hole along with six birdies to finish on 16-under-par 200 after three rounds.
The 23-year-old Spaniard, playing in only his third European Tour event, also had some luck saving a par on the 548-yard par-five 17th.
'I got very lucky there,' said the son of former Ryder Cup winner Jose-Maria Canizares.
'I drove the ball into the water from the tee, took a penalty drop, then hit the ball over the hill and it was going into the water again but it was stopped by the drainage tank.
'I got a free drop from there and then got down in two so I was very lucky.'
Canizares, who finished tied for seventh at last week's Dutch Open, leads Carlos Rodiles and David Drysdale, two of the three overnight leaders, who both shot 69s.
Another Spaniard Francis Valera, who shot 67 on Friday to move into a three-way tie for the lead with Drysdale and Rodiles after two rounds, struggled on a hot and humid afternoon at the Moscow Country Club in suburban Nakhabino.
Valera had three bogeys to finish two over par and drop six strokes behind.
Defending champion Mikael Lundberg of Sweden, who began the day tied for sixth three shots back, remained in contention with a 70 at 205.
This year the Russian Open became a fully fledged European Tour event for the first time in its 13-year history with one million euros in prize money.
Gary Murphy heads the Irish challenge on 13-under-par.
