South African Louis Oosthuizen has given himself yet another chance to win his first European Tour title - and with it a place in The Masters.
Runner-up to Welshman Rhys Davies in Morocco last week after leading by three with 15 holes to play, Oosthuizen takes a one-shot advantage over England's Robert Coles into the final day of the Andalucian Open in Malaga.
Only a victory will probably do for the 27-year-old in his bid for a second successive trip to Augusta, and a four-under-par 66 kept him on course.
Oosthuizen, who now stands at 14 under overall, said: "My putting has not let me down, but I'm not happy with how I hit a few iron shots.
"It's a low-scoring course, but the thing is you can try and attack it too much and make stupid bogeys. I made a few."
Coles has been on and off the Tour since his debut in 1995, making 10 trips to the qualifying school and never finishing higher than third in an event.
His 63 was his lowest round in 267 tournaments and lifted him from ninth to second.
Spaniard Gabriel Canizares, who on Friday had the first albatross of the Tour season, is only two behind the leader on 12 under following a 65.
Richard Finch in fourth on 11 under, with fellow Englishman Sam Hutsby, the joint overnight leader, one further back alongside Scot Peter Whiteford and Dutchman Robert-Jan Derksen.
