( CNN ) -- Danish veteran Thomas Bjorn carded six straight birdies on the back nine at Wentworth to revive his third round in spectacular fashion and take a five-shot lead into the final round of the European Tour 's flagship event at Wentworth . Bjorn , who has been at the head of affairs since a 10-under 62 in the first round , was slipping back through the field after dropping three shots in his opening five holes Saturday until he began his incredible run . A birdie on the sixth was the forerunner to his charge from the 11th -- which ended when he missed a three-foot birdie putt on the 17th for seven in a row . He completed his round on the 18th with his seventh birdie in eight holes for a five-under 67 . That took him to 15-under 201 , with England 's two-time champion Luke Donald leading the chasers after a 68 . Ireland 's Shane Lowery , who led overnight on 10-under with Bjorn , was next best , a further shot back . Former World No.1 Rory McIlroy recovered from a double bogey on his opening hole to card a 69 to be tied fourth on eight-under with Dutchman Joost Luiten ( 67 ) but seven shots behind the rampaging Bjorn . `` I would have to shoot ridiculously low tomorrow to have any realistic chance but even then Thomas is so far ahead , '' Northern Ireland 's McIlroy told the official European Tour website . The 43-year-old Bjorn has taken a particular liking to the back nine on the West Course , shooting 16-under for this half as against one-over for the front . `` I had a terrible start with some poor decisions but I settled myself down and knew I could play this back nine pretty well . I got the momentum and kept it going , '' he said . `` I 'm in a strong position going into tomorrow but the job is not done yet . `` There is a lot of golf to play and I know there are top guys just behind me who can shoot very low as well . So I have to maintain my concentration and form to the end . '' Heavy overnight rain delayed the start of the third round by three hours and players were allowed to place their golf balls on the fairways in preferred lies . It is the 60th edition of the prestigious tournament with the last 30 stagings at Wentworth , which is also the headquarters of the European Tour . Meanwhile , in the Colonial tournament on the PGA Tour , David Toms , Chad Campbell , Chris Stroud and Japan 's Hideki Matsuyama shared the lead on seven-under after the third round . In a bunched leaderboard , there were 49 players within five shots of the lead , including FedExCup points leader Jimmy Walker ( tied for fifth at six-under and world number one Adam Scott of Australia ( tied for 11th , two shots back .
