Pro V1x loyalists Lee Westwood and Ian Poulter both closed out their 2011 golf seasons Sunday in the same place: The winner's circle.

 Westwood cruised to a seven-shot victory at the inaugural Thailand Golf Championship in Bankok, while Poulter stormed to a three-shot win at the JBWere Australian Masters in Melbourne, capping another season of overwhelming success for Titleist golf ball players.

In 2011, Titleist Pro V1 and Pro V1x players combined for 175 wins across the worldwide professional tours, nearly 150 more than the nearest competitor with 27 and more than all competitors combined.

A total of 21,533 players teed up Titleist golf balls in worldwide pro events this season, more than six times the nearest competitor with 3,485 and more than all other golf balls combined.

• ASIAN TOUR: Lee Westwood's victory was his fourth of the season, as well as his second in three weeks (Nedbank Golf Challenge).

 He opened with a bogey-free 12-under 60 in Round 1, rolling his Pro V1x golf ball in for 11 birdies and one eagle to set the course record at Amata Spring CC.

Fifteen birdies and three rounds later, Westwood's name sat atop the leader board at 22-under 266, seven shots clear of the field.

Westwood, who also set a course record during his Nedback Golf Challenge victory with a 10-under 62 in Round 3, moved back to No. 2 in the Official World Golf Ranking.

"It means a lot, any win does…," said Westwood.

"The fact that I led wire to wire… There was pressure involved."

Westwood was one of 79 players in the field that trusted Titleist golf balls, nearly four times the nearest competitor with 20 and more than all competitors combined.

Pro V1x loyalist Juvic Pagunsan finished as the Asian Tour's Order of Merit champion with nearly $800,000 in earnings.

• AUSTRALIA: Ian Poulter started the final round of the JBWere Australian Masters two shots behind the leader. He quickly erased that deficit by dropping in his Pro V1x golf ball from 15 feet for eagle on the first hole – and he never trailed again.

 Poulter added birdies at Nos. 7 and 9 to take a two-shot lead into the back nine at a windy Victoria Golf Club, and finished with a 4-under 67 for a 15-under 269 total and three-shot triumph.

Poulter, also a winner this season at the Volvo World Match Play Championship, topped a leader board that included nine Titleist golf ball players in the top 11, including Titleist Brand Ambassador Geoff Ogilvy (Pro V1), who finished third.

A total of 94 players relied on Titleist golf balls for their success in the event, more than 10 times the nearest competitor with  nine and more than all other golf balls combined.

"To come down here the week before Christmas and to win this tournament is very special," Poulter said.

"After the first couple of days when there wasn't much wind people may have thought the Victoria Golf Club was easy, but they were mistaken. It certainly showed its teeth today."
