Jamie Donaldson was frustrated by "a big chance gone" after finishing joint-fourth in the BMW Masters in Shanghai.
The Welshman finished one shot behind Marcel Siem, Alexander Levy and Ross Fisher who played-off for the title with Siem coming out on top.
The 39-year-old missed a putt on the 18th which would have earned him a place in the play-off.
"I hit a perfect line but left it short in the middle, which is dreadful," said Donaldson.
"You've just got to laugh because there were so many chances out there to make up ground on the leaders, and I didn't quite play well enough to be there.
"Overall it's a big chance gone there. There was a tournament there to be won and and I just didn't do enough to do that."
After equalling the course record with a round of 62 on the third day, Donaldson struggled in windy conditions to card a three-over-par 75 on Sunday.
"It was a very difficult day - going from a flat calm to a three club wind is very difficult but the golf as a whole wasn't very good by all of us," added Donaldson, who finished on 15 under par alongside England's Justin Rose.
It was the first event of the European Tour's Race to Dubai Final Series, four tournaments that culminate in the World Tour Championship in Dubai from 20 to 23 November.
Donaldson is currently second behind Rory McIlroy in the Race to Dubai rankings after picking up more than £360,000 from the Shanghai tournament.
"It's good I suppose that played poorly today and still finished decent," said Donaldson.
"But golf is a frustrating game sometimes. I wasn't quite on it out there, but a top five finish in the first of the final four series is a good start."
