Tiger struggles to stay on the straight and narrow

AUGUSTA, Georgia - Tiger Woods returned to Augusta promising a cleaned-up act but delivered a mixture of the impossibly good and some bad golf plus a sprinkling of behavior bordering on the ugly.

He had promised a "more respectful" approach to the game but in many ways during four days of white-hot U.S. Masters competition, Woods showed he has not changed from the pre-scandal version of the world number one.

True, the worst expletives and club-throwing which have marred his majestic play of the last couple of years were gone but Woods still struggled to maintain his cool when a drive or approach shot soared a fairway's width away from its target.
