Tiger Woods won the 13th major of his career with a two-stroke stroke victory over Wood Austin in the US PGA Championship at Southern Hills, Oklahoma.

The world number one successfully defended his title after a final-round 69 proved enough to hold off his rivals and maintain his amazing record of having won every major in which he has led heading into the final round.

Woods began the day with a three-shot advantage over Stephen Ames but he soon disappeared from contention as Els and Woody Austin emerged as the main challengers.

The lead was up to five from Els after eight holes but a bogey at nine and a birdie for the South African at 10 cut that back to three.

However, Els bogeyed the 12th but the gap was back to three when the South African birdied the long 13th.

And when he holed a six-footer at the par-three next he was within two of Woods, with Austin moving alongside him after three birdies in a row from the turn.

Woods then bogeyed the 14th after his short putt lipped out and his advantage was just one from Austin after Els bogeyed the 16th.

Typically, however, the world number one clawed that shot back at the next with a 14-foot birdie putt.

Els finished with two pars for a final-round 66 to finish five under and when Austin failed to hole a birdie putt from long distance on the 18th he closed with a 67 to be second on six under.

That left Woods to get down in four from the middle of the 18th fairway and he found the centre of the green and two putted for his fourth US PGA victory.

North Yorkshire's Simon Dyson capped his first US PGA Championship with a round to remember at Southern Hills.

The 29-year-old from York had not played in a major yet this season but finished with a six under 64 in broiling conditions at the Oklahoma venue.

But Hartlepool's Graeme Storm, who led the event after the opening round, faded away over the weekend.

Saturday's 74 was followed by a 76 yesterday, as he finished in 62nd place on 13 over par.

Dyson missed the cut in his last two tournaments, but a break allowed him to come back refreshed and it showed as his 31 on the front nine was the low front nine of the week.

He explained: ''I put my clubs away for two weeks and didn't touch them. I had a few nights out with my mates and took my girlfriend away for a couple of days. Then as soon as I came back, I just started practising again and carried on at the gym.

''After two weeks off, I actually felt pretty good - then I flew out here and still felt good.''

He may have felt good, but Dyson did not get the results he was after in the early rounds, opening with a 73 and following up with rounds of 71 and 72.

His 64 yesterday included seven birdies and just one bogey and he added: ''My game has been in pretty good stead throughout the first three days.

''I was driving it well. The second day I did everything but hole a putt. I played quite a few practice rounds. I knew the course pretty well, liked it and it helped.''

Colin Montgomerie was three under for the round after a birdie at 15, his fifth of the day, but he faded. A bogey at 17 was followed by a double at 18 and an eight-over 288 total.
