Maikel Scheffers, one of the founding figures of wheelchair tennis, has announced his retirement after a career that took him to the top of the world rankings in late 2011. The Dutch player won grand slam titles in both singles and doubles, claiming the Australian Open and Roland Garros in singles and all four grand slam doubles titles, including two US Open victories. A five-time Paralympian with two bronze medals to his name, Scheffers will now focus on youth development and talent pathways in his existing role with the Dutch tennis federation (KNLTB).
