Newly-crowned Australian Open champ, Jordan Spieth has a seven shot stranglehold on the $US 1m Hero World Challenge event at Isleworth in Florida.

The 21-year old holed a stunning 50-foot birdie putt at the last in a round of 63 to be well clear of World No. 2 Henrik Stenson (68) and Keegan Bradley (65) sharing second on 13-under par.

Spieth is now on target to have his name etched on a second tournament trophy, and on a second continent in two weeks.

The last golfer to achieve such a feat was World No. 1 Rory McIlroy in capturing this year’s Open Championship on British soil and in his very next event capturing a first WGC title with victory in the Bridgestone Invitational in Akron, Ohio.

“It would mean a lot to get my name on two different trophies in two weeks,” Spieth said.

“It’s been a heck of a trip thus far, starting with Japan, just barely missing out, and then closing it out last week.   It would mean a lot to me.  This tournament consists of whatever it is, 18 of the top 30 in the world.  This is a world‑class field by every definition of it.

“These are the guys that win major championships.  Almost everybody in this tournament has won one.  I would say more than half.  You guys would know.

“Yeah, it would mean a lot to me going into the off season.  It would give me a lot of confidence going forward looking to 2015 to be a year that is an improvement on 2014, which is the ultimate goal.”

Spieth had joined Steve Stricker in returning to the course early on Saturday at 10.15am and needing to get up-and-down from just in front of the green after bad light forced him to mark his ball late on Friday.

The Texan chipped and putted for par before heading to lunch and then returning to post a nine under par 63 but under a ‘preferred lie’ rule.

“I’m really pleased as I was trying to go out today, I was in the lead by two, but obviously with a golf course that’s receptive I knew that there were low scores out there,” he said.

“So wanted to go out and get off to a good start and just post a solid round.  I wanted to keep the lead and then kind of keep the same attitude, mental kind of strategy that I had last week.

“Then got off to a dream start with a 20‑footer and a then a good bounce on 2 and a birdie on 3.  Yeah, from there it was rolling.

“Played the par‑5s well, which was important.  Played the easier holes well other than 16, and was able to hit some wedges in close and play some of the slopes.

“I didn’t have to make a lot of putts after really 1, and then the one on 14 and 18 were the ones that weren’t really tap‑ins.  That’s about it.

“So that was good, but that may not be the case tomorrow.  I really got to get out there and grind and keep my head down.”
