Nick Kyrgios won a match for the first time in nearly 2½ years on Wednesday at the Miami Open, beating Mackenzie McDonald while wearing a thick wrap of beige tape on his surgically repaired right wrist that he said was numb after he took five painkillers.

Up next for Britain's Raducanu will be American world number 10 Emma Navarro, who won a WTA 500 event in Mexico in early March for her second career title before losing in the third round at Indian Wells.

Nick Kyrgios has hinted that his Miami Open campaign could already be over despite winning his first match in more than two years. The former world No. 13 came from a set down to beat qualifier Mackenzie McDonald 3-6 6-3 6-4 on Wednesday, just days after he was left in tears when he retired injured in Indian Wells.
