Montgomerie saw his chances of overhauling US Open champion Michael Campbell in the EuropeanTourOrderofMerit this weekend fade away as his three birdies were cancelled out by a bogey and a double bogey for a second consecutive par 72.
The foundations for his win which moves him up to third in the European Tour's OrderofMerit were, of course, provided by his opening nine-under-par 63.
"I've dreamed for so long to win on the EuropeanTour, " said Jaidee, who is now fourth on the EuropeanOrderofMerit and top of the Asian Tour money list.
