'All I wanted to do was to go out and do my very best and that's what I did,' said Dodd. 'Sometimes it's not in your own hands. Sometimes, the other person plays really well and you can't do much about it. But fortunately, it was my turn to play well. I really can't put it to words, to be honest, I'm just delighted that I won.'
Thomas Bjorn matched Dodd's 68 to take second place at 9-under-par 279. Chawalit Plaphol and Jason Dawes fired rounds of 6-under 66 Sunday to share third place at 6-under-par 282. They were joined there by Thaworn Wiratchant, who posted a final-round 68.
Dodd began the final round with a three-stroke lead over Bjorn and Soren Hansen. Dodd and Bjorn, who were playing partners in the final round, each birdied the par-5 first at Shanghai Silport Golf Club.
The Welshman Dodd ran off four straight pars from there. He dropped in a birdie try at the par-4 sixth to move four shots ahead of Bjorn and Bradley Dredge. Bjorn slid five back as he dropped a stroke with a bogey at the par-4 sixth.
Dodd followed with a bogey at the next however. Hansen made a run at Dodd's lead with birdies at the sixth and eighth. However, Hansen's momentum was stymied with a bogey at the ninth.
The 38-year-old Dodd converted back-to-back birdies from the 10th to jump to minus-11, four strokes clear of Bjorn. Dodd kept rolling as he ran home a birdie putt at the 13th to move to 12 under.
Dodd stumbled to a bogey at the 17th, but closed the win in style with a birdie at the last.
Bjorn tried to keep pace with Dodd as he birdied the ninth, 10th and 12th to move to minus-8. After a pair of pars, Bjorn birdied the par-4 15th. He closed with three straight pars.
'There was not much I could do, he played really well,' said Bjorn of Dodd. 'From the sixth through to the 13th, I can't play any better. He made birdies and I didn't hole anything. Then I made that charge and I can't play much better than I did in those stretch of holes, and that's where you need to turn the tournament around and Stephen did all the right things.'
Steve Webster and Amandeep Johl shared sixth place at 5-under-par 283. Barry Lane, Jonathan Lomas and Hansen finished one stroke further back at minus-4.
Joon Chung, Mark Foster, Gregory Havret and Simon Yates each carded even-par rounds of 72 on Sunday to tie for 11th place at 3-under-par 285.
