After years out of the sport, wheelchair tennis player Anderson Parker may have thought he would never become a Paralympian. 

The Australian was finally able to make his debut overnight, going down in his men's first round singles match to Argentina's Ezequiel Casco, 7-5, 6-4.

Rain in Paris delayed their match for several hours after the duo had completed nine games of the opening set. 

The result was not what Parker had hoped for, but it was a far cry from the eight-year hiatus the 26-year-old had from the sport.

A talented teen, ranked the sixth best wheelchair tennis junior in the world, Parker was out of the sport when his disability was reclassified. 

Parker was born with talipes, a congenital foot deformity, and after a stint in wheelchair basketball he returned to tennis when his disability was reclassified again.

He fulfilled his grand slam dream earlier this year when he competed at the Australian Open and was selected to the Paralympic team for Paris.

Reflecting on his journey after defeat in Paris, Parker credited fellow countryman Ben Weekes with getting him back playing at a high level.

"I wouldn't have been able to get where I am now without hitting with Ben, as well as fixing all the habits that I've had as a junior after eight years. So yeah, a bit wild, still a dream," he said.

"This is all new to me, so I'm trying to (soak it up) as much as possible."

Weekes also went down in his first round match in Paris, falling to Brazilian Daniel Rodrigues 6-0, 6-1.

The pair will combine in the men's doubles as they continue their Paralympic journey in Paris. 

After losing eight years of wheelchair tennis, Parker said he is in the right frame of mind to make the most of every opportunity.

"I tried a little bit of wheelchair basketball, and it just wasn't for me. I know all the basketball players, and they're all lovely people and everything, but coming back to tennis, I just had that eight years to find myself, get more stable with my brain," he said.

"It's still getting there, but a lot more stable from when I'm a junior. So now it's sort of reopened again, and now I have all the energy and the fight to get here."
