Making the quarter-finals at a WTA tournament used to be no big deal for Naomi Osaka. It was only a shock if it didn’t happen.

Things are a bit different now.

The former world No.1 has made it through to the quarter-finals at the Miami Open — just the second time she’s managed to advance that deep in any event over the past year.

Osaka beat Alison Riske 6-3 6-4 on Monday, moving into a round-of-eight match-up with Danielle Collins.

Osaka’s only other quarter-final appearance in the past 12 months was at an Australian Open warm-up tournament in Melbourne in January.

Before that, it was at Miami a year ago.

“It’s really funny for me, because last year here I made it to the quarters, too,” Osaka said.

“It was after I won Australia and I wasn’t that grateful. I kind of expected to win.”

Wins these days just mean more, after ongoing struggles and time away from the game to deal with her mental health.

Her ranking in the world has dipped to No. 77 — it could get somewhere around No.30 if she wins the Miami title — and she hasn’t won a tournament since that Australian Open victory last year.

But her stay in Miami so far has been nothing but happiness, with three easy wins — all in straight sets — and the added benefit of a walkover victory in there as well.

“This is really one of the funnest times of my life,” Osaka said. “I’m really grateful.”

Ninth-seeded Collins cruised past world No.10 Ons Jabeur 6-2 6-4.

The win ensuring Collins is locked into the top 10 when the world rankings reset early next week.

She could be as high as No.8 depending on how far others go in the tournament, a career high.

Collins is 0-2 in previous matches against Osaka, both straight-set losses on hard courts, one in 2018, the other in 2019.

“When Naomi is at the top of her game, she’s very, very hard to beat,” Collins said.

Polish ace Iga Swiatek, who will be crowned the new world No.1 next Monday, crushed Coco Gauff 6-3 6-1 to storm into the last eight.

The 20-year-old Swiatek needed just 76 minutes to dispatch teenager Gauff and seal a 14th straight win — she remains undefeated at WTA 1000 events in 2022 having won titles in Doha and then at Indian Wells just over a week ago.

Meanwhile, resurgent Australian Daria Saville has won through to her first quarter-final at a top-tier event since 2017 by surviving a match point to outlast Italian Lucia Bronzetti 5-7 6-4 7-5 in three hours..

Saville has climbed a staggering 500 spots in the world rankings since mid-February; she was 627th in the world and could make it back into the top 100 if she wins her next match against Belinda Bencic or Aliaksandra Sasnovich.
