All business, Tiger Woods' star-studded Team USA are on a week-long booze ban as they look to put the Internationals to the sword for the eighth straight Presidents Cup.
Last time Woods was in Australia a decade ago, the 15-time major winner's world came crashing down after revelations of his infidelity and late-night antics first emerged.
But Rickie Fowler, one of Woods' captain's picks, has revealed there'll be no such partying - not until Sunday anyway.
The Americans made a pact pre-tournament they would have a dry week to ensure they were at their best as they looked to take down the Internationals.
"It was a team consensus; everyone just decided to have a dry week," Fowler told AAP at Royal Melbourne on Wednesday.
"It was an idea that was thrown out and everyone jumped on board.
"We are down here to play golf and try and play the best we can and we can celebrate and have some fun on Sunday night before we head home."
Woods, the first playing captain since 1994, has left no stone unturned in his preparation with the US players.
But his only nocturnal antics have been incessant text messages to teammates to fire them up.
The team shared drinks after Woods' tournament in the Bahamas last weekend and then a couple on the plane early in the 26-hour flight.
But since then it's been booze-free.
Fowler, who replaced injured world No.1 Brooks Koepka last month, said the team felt that staying away from alcohol would help them recover better from the long-haul flight.
The US are treating the threat of the Internationals seriously despite boasting all but Fowler in the world's top 20.
In the tournament's 25-year history the International team have only won once, in 1998, but that also came at Royal Melbourne.
South African veteran Louis Oosthuizen said this week he felt the mix of youth and experience gave his team their best chance of a win from the sides he's been involved in.
US spearhead Dustin Johnson, who is suiting up for his fourth edition, said his team would need to be at their best to continue their winning streak.
"They have a great team - we have a great team. We have to play well if we want to beat them," Johnson said.
