Lisbon - Spain's Rafael Cabrera-Bello will take a one shot lead into the final round of the Portugal Masters on Sunday thanks to a third round eight under par 64 at Oceanico Victoria Golf Course.
The 27-year-old, whose only European Tour title came at the 2009 Austrian Open, is on 18 under for the tournament and leads Sweden's Christian Nilsson and Chile's Felipe Aguilar by one shot.
Overnight leader Simon Khan fired a 71 to be at 14 under, in a tie for eighth place and four shots off the lead.
Cabrera-Bello carded five birdies, two eagles and one bogey in his round.
"It felt really good, I've been playing good the last few days," said the Spaniard.
"My goal today was to try and do the same thing. The two eagles definitely gave me a big boost and I think I played pretty solid.
"I did not make many mistakes. I've been hitting my irons really good this week, hitting them close and giving myself lots of opportunities and I've been able to make a few. Hopefully I can keep it up tomorrow.
"I probably won't be leading tomorrow by the time I tee off so I need to perform well and try to hit a low round again."
Former Saint Omer winner Nilsson is 89th on The Race to Dubai and knows his chances of reaching the Dubai World Championship could hinge on his final round showing.
"It's a big week for me," he said. "I'm trying to get into the Top 60, so I hope for another good day but you never know."
Sweden's Peter Hanson and Denmark's Thomas Bjorn are just two shots off the lead on 16 under, Hanson carding a 64 and Bjorn - seeking his fourth win of the season - returning a 66.
