Rio de Janeiro, State of Rio de Janeiro, Brazil, 14 September 2016 | tennis.com.au

Dylan Alcott and Heath Davidson have won gold for Australia after a dramatic victory in the final of the quads doubles event.

Alcott and Davidson beat the reigning Paralympic gold medallists Nick Taylor and David Wagner of the United States 4-6 6-4 7-5 in two hours and 44 minutes.

Taylor and Wagner were undefeated at Paralympic level in this event, winning gold in Athens 2004, Beijing 2008 and London 2012.

But the Aussie duo ensured a new team would emerge triumphant in Rio 2016.

Alcott and Davidson trailed 4-1 in the second set and 3-0 in the third before staging an incredible comeback.

“From that position, you play that match 100 times we lose 99 times with that scoreline. To come back and win … I thought we were cooked,” Alcott said.

“We stuck to our plan. I’m just so proud of Heath; I can’t believe how well we played.”

They combined for 31 winners to the Americans’ 20 and hit four aces to none in a powerful performance.

Davidson, who took a 10-year break from the sport before coming back in late 2015, said his return was “the best decision I’ve ever made.”

“I knew if we went back to our (game) plan we could get it done,” he said.

“We did that and I guess the score speaks for itself.”

Alcott will return to the court on Wednesday to go for his second tennis gold medal of the Games when he contests the quad singles final against Brit Andy Lapthorne.

He has already become one of a select few athletes to win Paralympic gold in two different sports; the Victorian was part of the Australian basketball team that won gold in Beijing.
