Naomi Osaka will make her first Miami Open semi-final appearance after defeating Danielle Collins 6-2 6-1 on Tuesday.

The Florida native and the 2022 Australian Open finalist were worlds apart on serve, with Osaka putting up 13 aces, while Collins served seven double faults and had a meagre first-serve rate of 37.8 per cent.

While dropping only three games provides ample reflection, Osaka was in almost total control, winning 28 of 38 total points on serve and over half of the points on return with 26 out of 45. Her 25 winners to three unforced errors only reinforced the dominant nature of the win.

The Japanese former world number one has not dropped a set en route to the semi-final, and did not face a single break point against Collins, who called a medical time-out to address a neck issue after the first set.

"I'm glad I was able to get through quickly," Osaka said post-match. "I focused on trying to hit a lot of really good returns.

"This is actually my first night match too, so I didn't know what the conditions were going to be like."

Osaka will face reigning Olympic champion Belinda Bencic, who comfortably saw her way past Daria Saville with a 6-1 6-2 win.

The Tokyo gold medallist progressed to her first WTA 1000 semi-final since Madrid in 2019, needing just 69 minutes to defeat the unseeded Australian.

With Saville serving at 51 per cent for the match, Bencic was all over the second look, winning 18 of a total 23 points in those scenarios.

The critical element of the match was the Swiss 22nd seed's ruthlessness on break point, converting seven out of total eight times.
