Emma Raducanu is through to her first WTA 1,000 quarter-final after a blistering straight-set win over 17th seed Amanda Anisimova in Miami.

The Briton was in brilliant form from the off against her American opponent and needed just 24 minutes to secure the first set on her way to a 6-1 6-3 victory.

It is the first time since her US Open triumph in 2021 that Raducanu has won four WTA main-draw matches in a row, and she was dominant in sweeping Anisimova aside.

Prior to this tournament, Raducanu had lost five of six matches since the Australian Open - and last week ended her partnership with coach Vladimir Platenik after just two weeks.

"I've come a long way in the last week since Indian Wells, I wasn't necessarily feeling great about my tennis, about everything," the 22-year-old told Sky Sports.

"This week I have some really good people around me who I trust and who I have fun with off the court as well. That's extremely important.

"When I play my best I am definitely authentic, true to myself and creative. I feel when I am boxed into a regimented way then I am not able to express myself in the same way. So I'm happy with how I realised that this week."

Raducanu broke in the opening game of the match and raced through the opening set without losing a point on her own serve.

It was her returning that most impressed, though, as she continually put pressure on the Anisimova serve.

The American grew increasingly angry as the first set went on and appeared to be struggling with a right wrist issue.

Following a medical timeout between sets, she was much improved but could still not prevent Raducanu breaking to go 3-1 up in the second.

Anisimova broke straight back but Raducanu once again demonstrated the resilience she has shown this week, breaking again before confidently serving out for the match.

"I just knew I had to dig every ball that I could and make it as physical as possible because I backed myself in that regard," the British number two added.

"I was happy with how I moved, how I extended the rallies from the first game, the first points and kind of just got in my opponent's head."

Raducanu will play world number four Jessica Pegula in the last eight after the American beat Ukraine's Marta Kostyuk 6-2 6-3.
