Andy Murray continued his bid for a fourth Olympic medal as he and Joe Salisbury reached the quarter-finals of the men's doubles in Tokyo.
The British duo backed up their impressive opening-round win to beat Germany's Kevin Krawietz and Tim Puetz 6-2 7-6 (7-2).
They will play either America's Rajeev Ram and Frances Tiafoe or Marin Cilic and Ivan Dodig of Croatia next.
Liam Broady will contest his singles match later on Tuesday.
No man has won four Olympic medals since tennis returned to the Games in 1988.
Murray and Salisbury - a two-time Grand Slam doubles champion - have come through both their matches in straight sets.
The Scot was advised not to compete in both the singles and doubles after picking up a minor thigh strain at the start of the Games and subsequently withdrew from the singles.
"When we spoke about playing, I told Joe that if I had any physical issues I'd prioritise doubles over singles and that's why I made the decision," Murray said.
"I'd have been annoyed with myself if I'd decided to play with the issue, made it worse, lost my singles and not been able to perform well in the doubles.
"Physically it'll be OK for the rest of the tournament, but I will need to take a break afterwards."
Greece's Stefanos Tsitsipas avenged his first-round Wimbledon loss with a 6-3 6-4 win over Tiafoe to reach the third round.
Argentine Diego Schwartzman also advanced, beating Czech Tomas Machac 6-4 7-5, while France's Jeremy Chardy overcame Russian Aslan Karatsev 7-5 4-6 6-3.
