He began the final round with a six-stroke lead and he didn’t give his pursuers even the slightest hint that he could be caught. He putted for birdie on all but one hole and when he drained a 30-foot bomb for a birdie two on the 17th hole, his work was done.

"Played a lot of boring golf today," Spieth said, "which was exactly what we needed."

The 23-year-old round out his tournament with a clinical two under 70 to keep former US Amateur champion and friend Kelly Kraft at bay.

"This is a bucket-list place to win – here, Augusta National, St. Andrews, there's only a few in the world," he said. "It feels really special. It was amazing walking up to the 18th green knowing that we were going to win. It's just such a unique position. I tried to soak it in.

“I've read a lot about the Bing Crosby. It seems like it was as good a time as anybody had in a tournament back in the day. This is a special tournament at an extremely special place for a golfer. It's hard to beat Pebble Beach.”

Heading into the final round it was the first time Spieth had held a 54-hole lead on the PGA Tour since the Masters, where he lost a six-shot lead and the Green Jacket on the back nine.

But there were no thoughts of that disastrous afternoon as he shut out the opposition by playing flawless golf.

He admitted later he thought back to the 2000 US Open at Pebble Beach when Tiger Woods dismantled the course and the opposition for his record 15-shot victory by adopting a strategy of trying not to make any bogies in the final round.

Woods didn't make a bogey over the final 26 holes in severe conditions. On a soaked Pebble Beach course, Spieth played the final 28 holes of the event without a bogey.

"That's a dream round when you're leading by a bunch," Spieth said.

FINAL LEADERBOARD

The win, once again, has the game buzzing about comparisons between Spieth and Woods.

Why? Consider this … the only other player in the modern era to claim nine PGA Tour wins faster than Spieth is Woods. With his victory at Pebble Beach, the Texan elbowed his way passed Jack Nicklaus as the second youngest to win nine events.

With the trophy sitting in front him he smiled when quizzed if was comfortable with comparisons to some of the biggest names in the history of the sport.

He said he doesn’t think any player, himself included, could possibly keep pace with the winning record established by Woods.

“I think less of [the comparisons] than I have in the past, but it’s an honour, it really is an honour,” Spieth said.

“But getting to where you’re the first guy, even including Tiger, to do something, is maybe the next goal. But that might be pretty hard.”

Back in the pack there was a strong showing from the Australians at Pebble led by World No.1 Jason Day, who climbed into a share of fifth at 12 under after his closing 67. Victoria’s Cameron Percy had his first top-10 finish on the PGA Tour since May 2015 courtesy of his final round three under 69.
