Jordan Spieth: Tiger Woods tied last as youngster wins in Florida

Jordan Spieth won the Australian Open earlier this year

American Jordan Spieth won the Hero World Challenge by 10 shots as Tiger Woods finished in a tie for last place.

The 21-year-old led from round one and carded a final round seven-under-par 66 to finish 26-under on 262.

Speith, whose closest challenger in Florida was Sweden's Henrik Stenson, told Sky Sports: "It was the most fun I have ever had playing holes of golf."

Woods, making his return from a back injury, had a triple bogey on 13 and tied on level par with Hunter Mahan.

Tiger Woods missed the cut in his last competitive tournament - the US PGA Championship in August

Woods shot 72 while Mahan had two double bogeys in a round of 75.

However, the 14-time major winner said he was delighted to be back swinging powerfully and pain free after his four-month lay-off.

"It feels good to feel that rush again," the 38-year-old said.

"I didn't hit the ball as well as I would like. My short game was awful. But I was able to play for four days and hit the ball the way I wanted to and that's progress.

"It's so nice to hit drives that hard again, take bunkers out of play, cut corners. I hadn't felt healthy enough to do that in a very long time."

Woods went into the final day with the modest goal of escaping last place in the 18-man event but fluffed two more chips, bringing his total to eight for his week.

Spieth, who won the Australian Open by six shots last week, carded six birdies and an eagle in his final round to win his second title of the year.

He also shattered the tournament record of 22-under 266, set by Woods in 2007.

The Texan said: "People want to see somebody come up and do what Tiger did and change a generation of golf.

"But right now I look at what the number one in the world, Rory McIlroy, did this year and I'm trying to chase him more than I am anything else."

England's Justin Rose carded a one-under 71 to finish tied sixth with Rickie Fowler on 11 under.

And Northern Ireland's Graeme McDowell also carded a 71 to tie with Bubba Watson in 11th on eight under.
