Northern Ireland's Rory McIlroy believes that there is still room for improvement in his golf game.
The 22-year-old was speaking after his play-off victory over Anthony Kim in Shanghai earlier today.
McIlroy had a chance to win the tournament in regulation but he failed to sink an eight-foot birdie putt on the 18th.
"It's something that I feel like I can still get better at is winning and putting yourself in the position to win when you're not playing your best," McIlroy said.
"Even if it's scrappy golf where you grind it out, you're going to win a lot more tournaments by doing that rather than playing your best golf the whole week.
"I was very happy I was able to pull this one out."
McIlroy's victory saw him pick up a cheque for £1.25m.
