Cameron Norrie sealed a semi-final spot at the Rio Open, continuing his title defence by seeing off Brazil’s Thiago Seyboth Wild in front of his own fans.

The British number one secured a 6-1 3-6 6-2 victory to head into the last four.

Norrie lost just two games in a handsome win over Tomas Barrios Vera in the previous round and picked up exactly where he left off on the clay.

He raced out of the traps, breaking Seyboth Wild’s second and third service games and holding his own to take the first set in little more than half-an-hour.

The stands filled up considerably after a quiet start and Seyboth Wild fed off the growing support as he put together a much-improved showing to level the scores.

With his opponent starting to grow in confidence and the noise levels rising, Norrie allowed errors to creep in with cracks in his first serve and a misjudged long forehand seeing him broken for the first time.

Seyboth Wild was strong enough to make that breakthrough count and set up a deciding set but found Norrie back on his game as he tore into a 5-1 lead, breaking twice more along the way.

Norrie missed his chance to finish things off at the first attempt, burning three match points as his South American opponent showed admirable resilience in a see-saw exchange of winners.

But he soon stacked up three more match points against the serve and converted the second of them as Seyboth Wild’s unforced error ended his fight after just under two hours.

“I was really proud of how hard I fought, it was so humid and tough physically,” he told Sky Sports.

“It was a tough one and the atmosphere was great. These are exactly the kind of matches you want to play.”
