Johanna Konta won a dramatic contest against Svetlana Kuznetsova to reach the Olympic quarter-finals – after Andy Murray eased into the last 16.
Konta, ranked 13th, converted her fourth match point to beat the Russian eighth seed 3-6 7-5 7-5 after three hours and seven minutes.
The 25-year-old from Eastbourne plays Angelique Kerber or Sam Stosur next.
Murray, the reigning Olympic champion, beat Argentina’s Juan Monaco 6-3 6-1 and next faces Italy’s Fabio Fognini.
Scotland’s Wimbledon champion, 29, has now won 14 matches in a row since losing the French Open final in June.
Mixed news for Murrays
The draw for the mixed doubles is out and, as things stand, Jamie Murray and Konta will be the only British representatives.
They will play Americans Jack Sock and Bethanie Mattek-Sands in their opening match.
Andy Murray and Heather Watson do not have a high enough combined doubles ranking to qualify, although they are the second alternates.
If two other pairs withdraw before the end of the first round, Murray and Watson will get a spot in the draw.
“The plan was always that Jamie was going to play with Jo,” said Andy Murray.
“Obviously Jamie is a way more experienced doubles player than me. And Jo is obviously playing well too. So they will have the chance to win a medal.”
Brothers Jamie and Andy were knocked out of the men’s doubles on Monday.
