Bjorn had eagles at the 10th and 14th holes -- both par 5s -- en route to a 7-under-par 65 and 72-hole total of 20-under 268. Even with a final-hole bogey, Bjorn finished two strokes ahead of Sergio Garcia and overnight leader Jamie Donaldson for his 15th European Tour victory.
Garcia had a strong charge of his own Sunday, using four straight birdies to close the front nine at 6-under and ending up with a 65. Donaldson had three birdies and a bogey for a 70.
Henrik Stenson had a final-round 67 and finished fourth at 16-under while Brendon De Jonge was fifth at 15-under following a 66 Sunday and Charl Schwartzel, who also was 6-under in the fourth round, was sixth at 13-under.
Garcia's strong close to the front side combined with a ninth-hole bogey by Donaldson left them tied for the lead but Bjorn passed them both with his eagle at 10th. It was his second eagle at the 547-yard hole in two days. He was 6-under on that hole for the tournament.
Four holes later Bjorn dropped in another eagle putt and his lead was three strokes. He added a birdie at 15, which was more than enough cushion for the final-hole bogey.
