AVONDALE, La. — It sounds like Justin Rose believes he’s had a breakthrough in the Big Easy.

The Pete Dye-designed TPC Louisiana doesn’t have a layout that would seem to suit Rose’s strengths. The Englishman also wasn’t accustomed to contending in tournaments that require gunning for birdies on nearly every hole, knowing that the leaders would be close to 20 under par by the end.

Yet, Rose pushed himself to swing aggressively and trust his initial reads on the greens. His approach produced 66 consecutive holes of bogey-free golf and some clutch birdies down the stretch to give him his first victory of 2015 at the Zurich Classic on Sunday.

“This is not in my wheelhouse,” Rose said of New Orleans’ PGA Tour stop, noting that his best results tend to come at tough courses requiring a cautious approach, where 10 under is a good final score. “You want to become a player that can win on every type of course, and I will take a lot of confidence from the fact that I was able to play a golf course that was, you know, you had to be very aggressive and shoot low and keep shooting low.”

Rose completed a 7-under 65 in the rain-delayed third round Sunday morning and closed with a 66 in the afternoon for his seventh PGA Tour title, holding off a late charge by Cameron Tringale, who finished just one shot back.

Rose’s four-round, 22-under 266 set a record on the course southwest of New Orleans that has hosted the city’s PGA Tour stop 10 times since 2005.

He has now won at least once in six straight seasons, the second-longest streak on the tour behind Dustin Johnson’s eight straight. He’s projected to jump from ninth to sixth in the world ranking.
