Two-time Olympic 800m gold medallist Caster Semenya has joined a South African women’s football team. The 28-year-old is unable to compete without taking testosterone-reducing drugs following a rule change by the IAAF, athletics’ governing body. It means she cannot defend her 800m World Championship title in Doha this month – though she is fighting the rule change through the courts.
Serena Williams has another opportunity of winning a record-equalling 24th Grand Slam singles title after beating Elina Svitolina to reach the US Open final. The American, 37, overpowered the Ukrainian fifth seed to win 6-3 6-1. Williams, seeded eighth, is aiming for her first Grand Slam win since giving birth in September 2017.
