Shingo Kunieda, Diede de Groot and Andy Lapthorne claimed the last men’s, women’s and quad singles Super Series titles of 2019 on Sunday at the US Open USTA Wheelchair Championships, as De Groot and Lapthorne made it back-to back Grand Slam and Super Series crowns in successive weeks.

Kunieda and De Groot will end the season as winners of four of the sport’s six Super Series singles titles after world No. 2 Kunieda clinched his seventh men’s singles title since 2006 at the Dwight Davis Tennis Centre in St. Louis following a 6-2 6-4 victory over world No. 1 Gustavo Fernandez.

Kunieda has therefore won the Cajun Classic, Japan Open, British Open and US Open USTA Championships crowns in 2019, beating Fernandez in the last two Super Series finals of the year, which are among five finals the world’s top two players have contested this season.

Fernandez won his one and only Super Series crown this year after beating Kunieda in the final of he BNP Paribas Open de France.

Due to an injury that Kunieda acquired during the course of the men’s singles final he and Fernandez withdrew from the men’s doubles final, handing a walkover to British third seeds Alfie Hewett and Gordon Reid and therefore giving Hewett and Reid back-to-back Grand Slam and Super Series titles in successive weeks.

De Groot edges Kamiji for first St. Louis title

World No. 1 De Groot completed a Super Series four-time for 2019 after earning her first career title in St. Louis.

A semi-finalist last season, De Groot beat world No. 2 Yui Kamiji 6-4 4-6 6-3 in this year’s final to add to her Super Series titles at the Japan Open, BNP Paribas Open de France and British Open, meaning that the Dutch 22-year-old has won the last four Super Series tournaments of 2019.

While De Groot and Kamiji have met in six finals this season, with De Groot winning fives of those title deciders, their only previous Super Series final was at the Japan Open, where De Groot prevailed before defeating Kamiji in the semi-finals of the British Open.

De Groot ended the tournament as a dual champion after she and Aniek van Koot were awarded a walkover in the women’s doubles final. The top seeds and calendar Grand Slam winners were due to meet South Africa’s Kgothatso Montjane and Britain’s Lucy Shuker before Montjane had to withdraw with injury.

Lapthorne completes US Grand Slam and Super Series double

Lapthorne recovered from the threat of just a second defeat against Cajun Classic champion Koji Sugeno to win a second set tiebreak and, ultimately, his second US Open USTA Championships crown in three years.

The world No. 2’s 6-2 6-7(4) 6-2 victory over world No. 4 Sugeno saw Lapthorne extend his a advantage over the Japanese player to 8-1 in career meetings as he joined Sugeno, Dylan Alcott and Dutchmen Sam Schroder and Niels Vink on the roll of honour of quad singles Super Series champions in 2019.

Only Alcott finishes the year as a two-time Super Series winner, while Lapthorne followed up his second US Open Grand Slam quad singles title with his second victory in St. Louis.

After winning a second set tiebreak to keep their title ambitions alive in their semi-final, USA top seeds Nick Taylor and David Wagner faced another tricky assignment in the final of the quad doubles. However, the three-time Paralympic champions and 11-time UNIQLO Wheelchair Doubles Master champions held on to complete a 6-3 7-5 victory over first-time Super Series finalists Robert Shaw and Lucas Sitholes.

Taylor and Wagner have now won the US Open USTA Championships title on eleven occasions.
