Nick Kyrgios and women's world No.1 Aryna Sabalenka have hit back at critics of their much-hyped "Battle of the Sexes" exhibition match.
Australian Kyrgios fended off the game's top female player with a 6-3 6-3 victory in front of a big crowd at Dubai's Coca-Cola Arena on Sunday, the 30-year-old admitting he was given a gruelling work-out.
The clash borrowed its name from the 1973 match between 29-year-old tennis pioneer Billie Jean King and 55-year-old former grand slam winner Bobby Riggs, which King won in straight sets.
