Wrestling is tipped to regain its Olympic status when the IOC votes on the 2020 Games program, but two Australians will be doing their utmost to cause an upset in Buenos Aires.
Having chosen the host city of the 2020 Games, the International Olympic Committee (IOC) will meet again in the early hours of Monday morning (AEST) to vote on the three sports hoping to make the cut for the Tokyo Olympics.
Wrestling is up against squash, bidding for the third time, and a joint bid of baseball/softball, both of which last appeared at the Olympics in 2008.
Victorian ex-MLB player Justin Huber will present on behalf of the World Baseball Softball Confederation (WBSC), while Australian squash great Sarah Fitz-Gerald is part of the World Squash Federation (WSF) delegation.
Wrestling is an incumbent Olympic sport, but has been in purgatory since the IOC's 15-person Executive Board (EB) shocked many by voting it off at a meeting in February.
The International Federation of Associated Wrestling Styles (FILA) has since made a series of changes to bouts, and the expectation is the IOC will turn to its most ancient sport while voting on something new.
"What I am hearing makes me optimistic but a vote is another matter," said Nenad Lalovic, elected FILA president after his predecessor was ejected following the EB decision.
The WBSC was only formed in December 2012, with the joint bid from baseball and softball coming a long way in a very short space of time to make the shortlist of three.
"It's a marriage of commitment and it's no surprise the union has been seamless," Huber told AAP.
Huber, who played for three MLB franchises and in competitions across four continents, was slated to be Australia's starting catcher at the 2004 Athens Games but suffered a knee injury.
The 31-year-old is desperate to ensure other Australian baseballers have the chance to fulfil their Olympic dreams, and was upbeat about the joint bid's hopes of winning over the IOC.
"I've never paid much attention to tags," Huber said of the WBSC's underdog status.
"We are happy with our presentation ... for our chances, I think it's anyone's guess still."
Squash has fought a 10-year battle - in 2005 it topped the list to be part of the Games but failed because it did have a required two thirds majority, which has since been replaced by a simple majority.
It has the endorsement of many global sporting superstars including Roger Federer and Andre Agassi.
"We are now more than ready," Fitz-Gerald said.
"Our sport has been on a journey of innovation in recent years, especially in the way it is broadcast and presented."
