Henrik Stenson has vowed to give it one last push on Sunday as he aims to win Olympic gold for Sweden.
The 40 year old's last two tournaments have been high-pressure affairs, with him claiming The Open Championship title after an enthralling final day battle with Phil Mickelson and then being in contention at the US PGA Championship before finishing in a tie for seventh.
He enters the final day in Rio de Janeiro a shot behind Justin Rose in the Olympic Men's Golf Competition, and he is determined to give it all again to finish on the top step of the podium.
"In my mind, we're still going for one thing," he said. "Even though the consolation prizes might be better here than some other events in a way, it's still the number one spot that I'm looking for and I'm going to try my hardest to make that happen.
It's been a long and tiring stretch for me the last month, so I'm just going to try and squeeze whatever I have left in the tank for the final 18 tomorrow - Henrik Stenson
Australian Marcus Fraser is two shots behind Stenson with the next closest challengers six shots behind the leader, but the 11-time European Tour winner still believes there could be final day drama down the field.
"Those guys aren't out of it," he said. "If there's a breezy day tomorrow and someone gets on a roll. I saw Rickie (Fowler) shot seven under, Justin shot six under. If someone that's in fourth position there shoots a score like that, they might put their name forward in the gold medal fight. So it's not over until it's over."
Fraser will go out in the final group on Sunday alongside Stenson and Rose after a 72 on Saturday saw him sit three off the lead.
The World Number 90 admits that he will the underdog with his playing partners both having won Major Championships, but the 38 year old knows he has a chance to win a medal for Australia as long as he sticks to his gameplan.
"Not in my wildest dreams did I ever think I would come to the Olympics and compete and now, all of a sudden, I have a chance of winning a medal," he said.
"It feels like I'm going to wake up from this dream at some point. This is why we practise and we want to be in these situations and see what we've got.
"Hopefully tomorrow I can go out there and play a bit better than I did today and continue to scramble when I need to and shoot a good score.
I couldn't think of anything better than putting something around my neck. Hopefully that comes off but I won't leave anything on the table. I'll give it everything - Marcus Fraser
"I probably need those guys to be a little bit off. Their best is a lot better than my best and I'm not hiding away from that. If I go out there and do a good job with my game and the way I play, I think I definitely have a chance, that's for sure."
