While Titleist Brand Ambassador Rickie Fowler has never been considered a tinkerer, the 22-year-old made a tweak to his equipment setup at last week's Kolon Korean Open that helped him capture his first professional victory.

For the first time in his career, Fowler played the Kolon Korean Open with four Vokey Design Spin Milled Wedges: 48•10º (bent to 47º), 50•08º (bent to 51º), 55•12º and 60•L (bent to 59º).

"I had always played 47-, 53- and 59-degree wedges," Rickie said earlier this week in an interview with Golfweek.com. "I had two weeks off prior to Korea. I worked with four wedges in the bag. It made me feel more comfortable within 130 yards or so. I had more comfortable swings with wedges."

 Rickie, who shot rounds of 67-70-63-68 at Woo Jeong Hills CC to finish at 16 under and win by six shots, said in the interview that he decided to make the change after taking a closer look at his statistics with caddie Joe Skovron.

Putting a fourth Vokey in the bag reduced the yardage gaps between Rickie's wedges, thereby improving his distance control and increasing the odds of hitting it closer to the hole.

"(We) noticed my rankings in that scoring zone, inside 150 yards, weren’t great and needed some attention," Rickie told Golfweek.com. "Outside of 200 yards, last time I looked, I was in the top three (in proximity to the hole).

"It’s great to be a top player from outside 200 yards, but I’d rather be that good from inside 100 yards. We felt like we should pay some attention to that. This was the start of that."

Rickie is continuing a four-Vokey setup this week at the PGA Tour's McGladery Classic at Sea Island (Ga.) Golf Club, the second-to-last event of the 2011 PGA Tour season.
