Many of the world's top wheelchair tennis players will be hoping to add to their titles at the British Open in Nottingham. The BBC will be showing live action from Thursday to Sunday when the tournament reaches its climax. The likes of newly-crowned Wimbledon doubles champions Alfie Hewett and Gordon Reid and fellow Britons Lucy Shuker and Andy Lapthorne will be leading the home challenge. Last year's ladies and men's singles champions Yui Kamiji from Japan and Gustavo Fernandez from Argentina are back to defend their titles alongside quad winner David Wagner. The Nottingham event is one of the Super Series tournaments, the level below Grand Slam and the end-of-season Masters events. Wheelchair tennis is similar to the non-disabled version of the sport but with one key difference - the ball can bounce twice although the first bounce must be within the court's confines. There are three different divisions - men's, women's and quad. Athletes in the men's and women's divisions have lower-limb impairments and are classified by gender. Quad division athletes have impairments in three or more limbs and are classified based on disability, not gender. Britain has a strong history in the sport and won six medals at the 2016 Rio Paralympics, more than any other nation, including gold for Gordon Reid who beat compatriot Alfie Hewett in the men's singles gold medal match.
