Pro V1x loyalist Lee Westwood's 38th birthday celebration was highlighted by a 3-under 69 and three-shot victory Sunday at the Asian Tour's inaugural Indonesian Masters.

It all added up to the 33rd international win of his career, not to mention a boisterous rendition of the "Happy Birthday" song from the gallery behind the 18th green at Royale Jakarta Golf Club.

“This will definitely be the most memorable birthday for me,” said Westwood, who finished at 19-under 269 and was the only player to shoot all four rounds in the 60s (68-66-66-69).

Westwood pulled away with three birdies on the back nine, including a 15-footer with three feet of break on the 11th green, "the hardest putt I had all day."

He rolled his Pro V1x golf ball in from 4 feet on 18 for the win, then spent the rest of the day watching the congratulatory Tweets (@WestwoodLee) roll in.

With the victory, Westwood also reclaimed his position atop the Official World Golf Rankings.

"It was quite a day, really. I knew it wasn't going to be easy with a five-shot lead," he told the Associated Press. "I'm experienced enough to know that patience is the key."

Westwood was one of 103 players at the Indonesian Masters that trusted a Titleist golf ball, including six of the top 8 finishers, more than five times the nearest competitor with 18 and more than all competitors combined.

Westwood's win was also one of two on the weekend for Titleist golf ball players, as Pro V1x loyalist Nicolas Colsaerts cruised to a four-shot victory at the European Tour's Volvo China Open.

In total, Titleist golf ball players have won 38 times across the worldwide professional tours in 2011, nearly five times the nearest competitor with eight and more than all competitors combined.

• EUROPEAN TOUR: Colsaerts' victory at the Volvo China Open was nearly flawless, as he closed with a bogey-free 6-under 66 for a 24-under 264 total and four-shot victory, the first of his European Tour career and only second for Belgian-born players.

For the week, Colsaerts totaled 24 birdies, one eagle and just two bogeys at Luxehills International Country Club, showing off an impressive combination of both length and precision while setting the tournament scoring record by five shots.

Colsaerts, 28, led the field in Driving Distance (316.3 yards) and finished sixth in Greens in Regulation (86.1 percent).

“I’m enjoying every second of it,” said Colsaerts. “I’m dizzy – my head is going all over the place.

'I’ve been waiting for this for a very long time and I think I did it in the best of manners so I’m really delighted."

Colsaerts was one of 109 players that played a Titleist golf ball at the Volvo China Open that, more than five times the nearest competitor with 19 and more than all competitors combined. Titleist also was first in Iron Sets (55): and Sand, Lob and Approach Wedges (155).

• PGA TOUR: Titleist was the overwhelming golf ball of choice at The Heritage with 83 players, nearly six times the nearest competitor with 14. Titleist also was first in iron sets (37): sand, lob and approach wedges (122); and putters (48).

• JAPAN TOUR: A total of 65 players at the Tsuruya Open trusted Titleist golf balls, more than double the nearest competitor with 30. Titleist also was first in Hybrids (41), including 25 new 910H models; and Sand, Lob and Approach Wedges (112).
