British number one Kyle Edmund reached the quarter-finals of the Washington Open for the first time with a three-set win over Jo-Wilfried Tsonga.
Edmund, 24, came from behind to beat the Frenchman 4-6 6-3 6-4 in two hours 23 minutes.
The 13th seed will play Canada's eighth seed Milos Raonic or Germany's Peter Gojowczyk in the last eight.
Edmund is aiming to become the first Briton to reach a singles final in Washington since Andy Murray in 2006.
On that occasion, now three-time Grand Slam champion Murray lost to France's Arnaud Clement, while Tim Henman was the last British winner of the tournament in 2003.
