Para-standing tennis is supported by the International Tennis Federation, with more than 400 recognised players now competing in the sport.
There is hope from many players that they can mount a bid to be part of future Paralympics events.
Grover, who is also the current para-standing tennis World Singles Champion, said: “When you look at other variations of sport, like table tennis and badminton, they have a standing and wheelchair class at major events.”
He added: “We want the standing class to be part of grand slams and the Paralympics in the future.”
The pair have had first hand experience of interest from spectators at major events.
Grover said: “I played on court next to Daniel Medvedev, there were huge crowds watching us that day.
“There are fans that are engaged, it’s just trying to grow that.”
