Heath Davidson, the Australian charged with following the success of his title-laden former wheelchair tennis partner Dylan Alcott, has made a superb Roland Garros debut by reaching the quad doubles final at the French Open.

The 35-year-old is now the last Aussie representative at the Paris slam after John Peers earlier on Wednesday crashed out of the mixed doubles in the semi-finals.

Davidson, who also linked up with fellow Victorian Alcott for Paralympic gold in 2016, has a new partner in Brazilian Ymanitu Silva following the retirement of his 23-time grand slam title-winning colleague.

Davidson and Silva opened up their title bid with a 1-6, 6-4 (10/8) win, edging the super breaker against the second seeds, Briton Andy Lapthorne and American veteran David Wagner, after an hour and a half.

Davidson, the four-time Australian Open doubles champion with Alcott, has now reached a seventh grand slam doubles final, but his first without his old partner.

Davidson and Silva will face the winner of the other semi-final — between top-seeded Dutch pair Sam Schroder and Niels Vink and South Africa's Donald Ramphadi and Japan's Koji Sugeno — in the final.

Davidson will begin his quad singles campaign in Paris at 7pm AEST tonight against Sugeno.   

On Court Suzanne Lenglen, John Peers's hopes of finally reaching a grand slam mixed doubles final were ended once again alongside Canada's Gabriela Dabrowski, as they were defeated by Japan's Ena Shibahara and Dutchman Wesley Koolhof 6-3, 6-4.

World number 15 Peers had been savouring a career-best run in Paris, advancing to his first semi-final there but, just as in his mixed doubles last-four appearances in the other three slams, the 33-year-old could not make it to the final.
