Estoril: Britain's Kyle Edmund knocked out Australian teenager Alex de Minaur with a 6-2, 7-5 win to reach the quarter-finals of the Estoril Open on Wednesday.
De Minaur is based in Spain and clay is his favoured surface but he had few answers as Australian Open semi-finalist Edmund advanced in 97 minutes.
Edmund, ranked a career-high 23rd, achieved his best Estoril showing after losing in the second round last year to Benoit Paire.
"I felt really good with how I played throughout," the third seed said. "I faced a tough opponent, who is very resilient.
"He didn't give away a lot of points, I had to work for this win. But I enjoyed winning a tough test, delivering in a pressure match.
"I've trained with Alex. I know he has a difficult game. He likes to counter-attack and use the pace to deflect.
"I knew how the match would go. I had to execute and impose my game to win it."
The Briton will next tackle Portuguese number one Joao Sousa, who needed two and a half hours to knock out namesake and compatriot Pedro Sousa with a 4-6, 7-6 (7/1), 7-5 win.
Edmund broke De Minaur five times as he played for the first time since a first-round loss in Monte Carlo.
De Minaur, 19, is still alive in the doubles alongside his 37-year-old Davis Cup captain Lleyton Hewitt.
The field in Portugal is headed by US Open runner-up Kevin Anderson, with the South African to start his campaign on Thursday against Greek rising star Stefanos Tsitsipas, the losing finalist last weekend to Rafael Nadal in Barcelona.
