The United States’ David Wagner will meet Brazil’s Ymanitu Silva in the quad singles final at the Swiss Open after the world number one and top seed moved to within one match win of clinching a 12th title in Geneva.

Wagner made it 25 successive singles wins in the city since 2011 by powering to a 6-0, 6-1 victory over Italy’s Alberto Corradi at the International Tennis Federation 1 Series tournament, part of the UNIQLO Wheelchair Tennis Tour.

Brazilian second seed Silva had a much tougher time in his semi-final, claiming a 7-5, 6-4 win over America's Greg Hasterok and booking his place in his fifth singles final at the Centre Sportif du Bois-des-Frères.

Wagner and Silva are also set to meet in the quad doubles final after both semi-finals ended in scorelines that mirrored the other.

Top seeds Antony Cotterill of Great Britain and Wagner beat Sweden’s Petter Edstrom and Canada’s Mitch McIntyre 6-0, 6-4, while second seeds Hasterok and Silva overcame Thailand’s Nutthaporn Taosrisagul and Sombut Yampapha 6-4, 6-0.

In the women’s singles event, defending champion Kgothatso Montjane of South Africa found herself a set down and needing to win a second set tie-break in her quarter-final against Japanese fifth seed Manami Tanaka.

Japan Open semi-finalist Tanaka’s hopes of reaching the last four of a Super Series event for the second time this season, however, came undone and world number eight Montjane extended her title defence with a 5-7, 7-6, 6-2 victory.

The second seed next is due to play Dutch third seed Michaela Spaanstra, who made her contribution to ending the Japanese challenge with a 6-2, 6-4 win over Momoko Ohtani.

Both quarter-finals in the top half of the women’s draw were hard-fought contests, but in the end doubles partners Lucy Shuker of Britain and Dana Mathewson of the US won through to set up a meeting between them tomorrow.

Shuker advanced by wrapping up her second victory of the season over Thailand’s Sakhorn Khanthasit, 6-4, 7-6, while Mathewson’s first meeting with last week’s Barcelona Open champion Angelica Bernal of Colombia ended with the 27-year-old winning 6-4, 6-4.

Belgium’s Jef Vandorpe, the reigning Junior Masters champion, earned his first completed match win over Dutchman Tom Egberink to reach the last eight of the men's singles event to guarantee that there will be a Belgian player in the final on Saturday (July 7).

Vandorpe's first career match against Egberink ended with the Dutchman retiring at the end of the first set before Egberink won their next match.

But the fifth seed dug deep today to force a deciding set, which he then dominated to close out a 4-6, 6-3, 6-0 victory.

Next up for him is compatriot and top seed Joachim Gerard, who remains on course to regain a title he last won in 2016 after beating Thailand’s Suthi Khlongrua 6-1, 6-2.

Second seed and defending champion Takashi Sanada of Japan and third seed Nicolas Peifer of France are set to  meet in the other men’s semi-final.

It comes after they both posted 6-1, 6-0 quarter-finals wins over Russia’s Leonid Shevchik and Italy’s Ivan Tratter respectively.
