Luiten overcame a four-stroke deficit with a bogey-free final round of 6-under-par 65 for a 54-hole total of 15-under 198. The tournament was reduced to three rounds because of poor weather through the event.
Daniel Chopra, who had the lead after the second round, shot 1-under 70 Sunday and finished second at 14-under. Defending champion Padraig Harrington and James Morrison each shot 69 Sunday and tied with Rhys Davies for third at 13-under. Davies matched Luiten with a third round of 65.
Luiten, who opened the tournament with an 8-under 63, had three birdies over Nos. 2-4 and closed his front nine Sunday with birdies at 8 and 9 to grab control. He added another at the 11th and finished with seven consecutive pars.
Chopra had a birdie at the fifth hole but fell back with a double bogey 6 at the seventh hole. He bogeyed the 10h but managed to salvage a second-round finish with birdies at 13, 16 and 18.
