Jason Day is looking for a winning edge; Marcus Fraser simply wants to share a special moment with a mate from home.

Jason DayTwo of the eight Australians teeing it up at the 119th US Open Championship at Pebble Beach Golf Links from late Thursday night AEST, Day and Fraser are preparing for their opening rounds with familiar faces carrying their respective golf bags.

Day has enlisted the help of golf’s most accomplished caddy of all time in Kiwi Steve Williams, the man who helped to guide Tiger Woods to 13 of his 15 major championships including his record 15-stroke win at Pebble Beach in 2000.

Williams, who was on the bag with Adam Scott for his 2013 Masters triumph, is only a part-time caddy these days, working with Ryan Fox when he plays at home in New Zealand.

It is not yet known whether the Day-Williams partnership will be an ongoing one but Williams is excited about Day’s prospects at a course where he has excelled in the past.

"There are a lot of very good players in the game and I consider Jason one of those capable of winning big tournaments," Williams told AAP at Pebble Beach.

"It's early days but to have the opportunity to caddie for one of the top Australian players is really exciting."

Top five in each of his past three starts at Pebble Beach at the AT&T Pebble Beach Pro-Am, Day has twice finished runner-up at the US Open as he endeavours to add to his lone major title to date at the 2015 US PGA Championship.

The expectation for Fraser is far different.

Like Williams, Fraser considers himself a part-timer these days, making occasional excursions to Asia and Europe in between rounds at his home club, Peninsula Kingswood Country Golf Club south of Melbourne.

That is where Fraser plays regularly with retired AFL legend Brendon Goddard who jumped at the chance to share the Pebble Beach experience.

Goddard has history on Fraser’s bag, caddying for his great mate at last year’s Hong Kong Open. When Fraser entered US Open Sectional Qualifying at Walton Heath in England he promised the St Kilda and Essendon great that if he got through he could come along, Fraser as shocked as anyone at the opportunity now before them.

“Given my current form, I didn’t think I had any hope whatsoever,” Fraser told RSN’s breakfast program, referencing his three missed cuts prior to Sectional Qualifying.

“I’ve been lucky enough to play the Open Championship at St Andrews a couple of times.

“I think playing the US Open at Pebble Beach has the same kind of ring to it.

“It’s going to be pretty special.”

The crowds when Fraser tees off in the opening group of the tournament won’t come close to the crowds Goddard played in front of in grand final appearances in 2009 and 2010 but he expects the nerves to be even greater.

"Definitely on the first tee at Pebble Beach, even as caddy," Goddard told AAP.

"I'm a little out of my comfort zone; being on the footy field in front of 100,000 fans felt more natural to me.

"But it's great to feel those butterflies and anxiety again."
