De Minaur bows out at ATP event in Estoril

Australian wildcard Alex de Minaur has been knocked out of the Estoril Open by Brit Kyle Edmund

Alex de Minaur has been beaten in straight sets by Briton Kyle Edmund in the second round of the Estoril Open.

The teenage Australian, who was granted a wildcard into the tournament, lost 6-2 7-5 to the third-seeded Edmund in an hour and 37 minutes.

World No.23 Edmund surged to a commanding set and 4-2 lead before 19-year-old de Minaur fought back to win the next three games.

However, Edmund broke again at 6-5 before serving out the match.

"I think I played a good match because de Minaur is a really good competitor and he moves well," Edmund said.

"It was a quality match."

Edmund will play Portugal's No.1 singles player Joao Sousa in the last eight.

The 'Conquistador', as he is affectionately known by the home crowd, beat compatriot Pedro Sousa 4-6 7-6 7-5 to advance.

American Frances Tiafoe made it through to the quarter-finals with a straight sets win.

The 20-year-old, who won his first senior ATP title at the Delray Beach Open in February, dispatched fourth-seeded Gilles Mueller with a 6-4, 7-5 victory.

Italian qualifier Simone Bolelli will play Tiafoe in the last eight after he overcame Argentine Federico Delbonis 3-6 7-5 6-2.
