Britain’s Lucy Shuker and Shota Kawano of Japan claimed two titles apiece at the German Open wheelchair tennis event, winning both the singles and doubles in their respective categories in Berlin.

Top seed and world number 10 Shuker secured a three-set victory over defending champion Katharina Kruger of Germany in the women’s singles, edging a narrow contest 6-1, 2-6, 7-5 to stun the home crowd.

Earlier on, she comfortably beat compatriot Louise Hunt 6-3, 6-3 in the last four to set up a meeting with Kruger, who swept aside Kanako Domori in her semi-final match, dropping just one game on her way to a 6-0, 6-1 success.

The two beaten semi-finalists then teamed up to take on top seeds Shuker and South Korea’s Ju-Yeon Park in the doubles, and the favourites managed to prevail with a 6-1, 2-6, 7-5 victory.

The triumph for Shuker and Ju denied the recent Australian Open winners their second consecutive German Open crown and handed the British player her second title of the event.

Kawano, seeded second for the men’s quad singles event, came up against team-mate Mitsuteru Moroishi in the final and despite dropping the opening set, he eventually clinched a 3-6, 6-1, 6-2 win to earn his second title of the season.

The Japanese player cruised to a confident 6-4, 6-1 victory in his semi-final clash with Dorrie Timmermans-van Hall of The Netherlands, while compatriot and top seed Moroishi overcame the tough test of young German Maximillian Laudan by virtue of a 6-2, 6-2 scoreline.

Although they were rivals in the singles competition, Kawano and Moroishi had earlier sealed the quad doubles crown by beating American Greg Hasterok and Israel's Itay Erenlib 10-6 on the championship tie-break third set after both teams had claimed a set apiece.

Elsewhere at the German Open, a International Tennis Federation (ITF) 2 Series event, the success continued for the British players as 17-year-old Alfie Hewett recovered from losing the first set before clinching a 3-6, 6-2, 6-3 triumph against Frenchman Frederic Cattaneo.

Unlike his compatriot Shuker, he was unable to claim two titles as he and Martin Legner were on the wrong side of a 6-2, 6-1 scoreline at the hands of Dutchman Tom Egberink, who lost to Hewett in the singles semi-final, and beaten finalist Cattaneo in the quad doubles final.

The next ITF 2 Series tournament will be the Birmingham Classic, due to take place in Mississauga, Canada, from September 10 to 13.
