PREVIEW-Golf-In-form Sabbatini seeks greater consistency

FORT WORTH, Texas, May 26 (Reuters) - South African Rory Sabbatini, energised by his victory at the Byron Nelson Championship, bids to build on his winning form at this week's Colonial Invitational.

A five-times champion on the U.S. PGA Tour, Sabbatini has long targeted greater consistency at the highest level.

"One of the things I've always been struggling with is to try and maintain a consistency," the 33-year-old told reporters in the build-up to Thursday's opening round at Colonial Country Club.

"It's nice to see that that consistency is starting to develop. Obviously, I had two bad weeks but I was able to flush those out and come back and play well."

Sabbatini, who won the 2007 Colonial tournament in a three-way playoff, had missed the cut in his previous two PGA Tour events before sealing victory by two strokes on Sunday.

"I got sick at Wachovia and tried to play when I was really weak," said the Texas-based South African, who has recorded three missed cuts and four top-10s in 13 PGA Tour appearances this season.

"I just let a few bad habits creep into my swing trying to develop some power to carry it over to the next week."

IN-FORM CASEY

Like Sabbatini, Britain's in-form Paul Casey will tee off at Colonial fresh from victory last week.
