Tiger Woods goes from hero to zero . . .

Woods, who struggled with illness throughout the week at Isleworth, posted a final round 72 for a level par tally and be tied in 17th place with fellow American Hunter Mahan in the 18-man $US 3.5m event.

The former long-time World No.1 came into the event after a four-month injury lay-off having shot a pair of 74s to miss the cut in August??s PGA Championship.

However there was little roar from the 14-time Major winner in posting scores of 77, 70, 69 and then recording four birdies, a bogey and a hurtful triple bogey at 13 on the private estate where he was a resident for more than a decade.

??I waited four months for this week and I feel I am making some progress. I??ve got no pain in my back and with some of the drives I??ve hit this week it really enforces that, so I??ve done the right thing with my body," said Woods.

??It??s been a process to get back to now. I've been hurt. I've been out of it for a long time. I've had to make my run to get back there.

"I was out for a while with my Achilles, and in two years I won eight times. So to win again is a process to get back to that winning level. You got to build up to it.

??But for now I will probably practice all this coming week and then shut it down for the holidays and then get back to work early in the New Year. I??ve got my back feeling good again so I want to reinforce it on the range and there is a lot of need to do with my short game.

??So overall it??s just nice to go out there and hit driver and take bunkers on without feeling any pain.??

Woods ended his round with 21-year old sensation Jordan Spieth storming his way to a second straight victory and seven days after capturing the Australian Open in Sydney.

The Dallas-born Spieth eclipsed World No. 1 Rory McIlroy in capturing three events in just two full seasons in the pro ranks whereas it took McIlroy nearly four seasons to win a third Tour title in capturing the 2011 US Open.

"This is impressive what he??s done this week and while he won here while still in college what he??s done this week is pretty much been all green light," said Woods.

??The last five rounds Jordan??s played, including that final round 63 to win last week??s Australian Open, and he??s flown 9,000 miles to get here so the four days here has been some pretty special golf right now.

??If you look back to what Jordan??s done in college, he??s been the benchmark and in winning you understand how to get it done

But there was double delight for Woods in that girlfriend, Lyndsey Vonn, and who is also returning to competition after a serious injury, won a first downhill ski event in Canada while Woods niece, Cheyenne Woods qualified to compete on the 2015 LGPA Tour.

??I??m pretty proud of Lyndsey as she just had a second today in a Super G and she??s back to competing, and back to where she believes she could get to and she??s finally there," he said.

??And it??s pretty exciting for Cheyenne as she has worked her tail off to get where she is now, and competing all over the world and played in everything she possibly could and she??s earned her card."

While Woods was struggling, another multiple major winner was hinting at a career revival as Padraig Harrington held off a late challenge from Thailand's Thanyakon Khrongpha to win the Asian Tour's Indonesia Open by two shots.

Ireland's two-time Open Championship winner came through a stuttering start to the final round and then a thrilling 18th hole to card a winning total of 16-under-par 268.

The victory was Harrington's first at a full-field tournament since he lifted the Johor Open title in 2010.

It was not plain sailing for the world No.385, who had entered the final day with a four-shot lead before a poor start allowed Thanyakon to go two shots clear after nine holes.

A two-hour rain break seemed to stall the Thai's momentum, however, and Harrington fought back to restore parity with his rival heading to the 18th.
