Swede Robert Karlsson jumped into the Dubai World Championship lead in spectacular fashion.
Starting his final round three behind Ian Poulter the 2008 European number one birdied the first two holes and then sank his approach to the 452-yard third just as current money list leader Martin Kaymer did on Thursday.
Four under par for his first three holes Karlsson was 13 under par and one ahead of Poulter, who had resumed two in front of the field.
With Graeme McDowell only one under for his first 12 holes and therefore three under for the tournament Kaymer looked certain to be crowned this season's number one.
The Ulsterman needed a top three finish just to have a chance and he was in joint 26th spot.
Karlsson came back to earth with bogeys on the fourth and sixth - both par threes - and with Poulter dropping a shot at the third the pair were joint leaders with defending champion Westwood and Spain's Alvaro Quiros.
Westwood, however, then bogeyed the 461-yard eighth.
