Casey: I want to take my game to the next level; GOLF.

Byline: Simon Lewis

HE MAY be golf's world No.3, but Paul Casey feels he needs to take his career up another level by winning a World Golf Championship event.

Having won three times this year, including a maiden victory in the United States at the Shell Houston Open, Casey will tee it up at Firestone Country Club in Ohio tomor-rohoping to add success at the Bridgestone Invitational to two previous top-10 finishes in the event.

The tournament comes at the start of a nine-week stretch in which Casey will play seven big tournaments, including next week's USPGA Championship at Hazeltine, and the Englishman is acutely aware that there are still hurdles to clear before he can feel he is as good as he thinks he can be.

"Every tournament from here on out is very, very important," Casey said.

"I've got to focus on the majors and the World Golf events. That's what I want to win.

"I've now won on the PGA Tour and lots (10) in Europe, but I need to continue to get better and win big events.

"And then we're into FedExCup and then after that right to the Race To Dubai. So there is no opportunity to back off at this point."

Fourth in 2006 and eighth last year, Casey feels right at home at Firestone.

"This is a golf course that I love," Casey said. "I think it's a wonderful track. I played nine holes on Monday, a few holes on Tuesday morning and, as ever, the fairways are pretty tight and you've got to find those if you want to shoot low scores."
