In an impressive display of confidence and control, Titleist Brand Ambassador Adam Scott won the World Golf Championships event at Firestone Sunday trusting a Titleist Pro V1 golf ball and a bag full of Titleist equipment.

Scott, 31, closed out the tournament with a bogey-free 6-under 65 that included a back-nine 31 and a birdie on No. 18 to capture his eighth PGA Tour victory and lead a 1-2-3 finish for Titleist golf ball players.

Scott was also one of four Titleist Brand Ambassadors to claim victories around the globe Sunday, including Scott Piercy's one-shot victory at the Reno-Tahoe Open, the 13th victory by a Titleist Brand Ambassador on the 2011 PGA Tour.

 In total, Titleist golf ball players have won 103 times across the worldwide professional tours in 2011, nearly seven times the nearest competitor with 15 and more than all competitors combined.

At Firestone, Scott took charge with an eight-birdie, zero-bogey 8-under 62 on Thursday and and never let up, especially on the back nine.

He played Firestone's final nine holes in 12 under for the week, making just one bogey over that stretch during the four days, hitting his Titleist MB irons close and rolling in his Pro V1 golf ball with his Scotty Cameron Kombi Long putter.

On Sunday, Scott chipped in for birdie from the side of the par-3 12th with his Vokey Design Spin Milled wedge then rolled his Pro V1 in from 30 feet for birdie on the par-4 14th to take a three-shot lead. He dropped in a 15-footer to save par on the par-3 15th and finished off his wire-to-wire victory with a 4-footer for birdie on 18.

"The way I closed it out, I was really happy," said Scott, who finished at 17-under 263, topping a leaderboard that featured eight Titleist golf ball players in the top 10, including the runner-ups, Titleist Brand Ambassador Rickie Fowler and Pro V1x Loyalist Luke Donald. Both Fowler and Donald finished in 4-under 66 for 13-under 267 totals.

"It was a great day on the golf course for me. I went to the range and had the best warm-up of the week. …  (My swing) felt great in the warm-up, so I was confident going to the course," Scott said. "I just had to kind of control myself a little bit and stay patient and not get ahead of myself. So went out there with a good strategy… and ended up playing a really solid round of golf."

For the week, Scott finished fourth in putts per greens in regulation (1.62) and T-9 in greens in regulation (70.8 percent).

Scott was one of 39 players in the event that relied on Titleist golf balls for their success, three times the nearest competitor with 13 and more than all competitors combined. Titleist also was first in iron sets (20); and sand, lob and approach wedges (61).
