She will face Iga Swiatek on Sunday, with the winner rising to number two in the world rankings.

Poland's Swiatek beat Romanian Simona Halep 7-6 (7-6) 6-4 to register her 10th consecutive victory.

Sakkari hit 28 winners during the match against Badosa.

She has won one title on the WTA Tour - at the Morocco Open in 2019 - but found more consistency last year, reaching the French Open and US Open semi-finals.

"I'm turning 27 this year, which is not old, but not young as well, and I'm just more mature and things change in that age," Sakkari said.

"Having a team like the one I have that constantly repeat that they believe in you, trust you and they're just very proud no matter what, it makes things a lot easier."

Sakkari leads the head-to-head with Swiatek 3-1, but Swiatek won their most recent meeting at February's Qatar Open.

"I know Iga really well and she's an unbelievable player," Sakkari added.

"I respect her a lot and I admire her game. It's just going to be an unbelievable fight for both of us."

Former French Open champion Swiatek fought back from a break down in both sets against Halep to reach the final.

She saved two set points in the tie-breaker before eventually clinching the opener, and overturned a 4-2 deficit in the second.

Swiatek reached the Australian Open semi-finals at the start of the year before lifting the title in Doha last month.

"I feel like I'm not the underdog any more and I want to show something else and show what I learned," Swiatek said.

"I always feel like I have nothing to lose, but this time it was a little bit different."

In the men's draw, American Taylor Fritz set up a semi-final meeting with seventh seed Andrey Rublev.

Fritz beat Serbia's Miomir Kecmanovic 7-6 (7-5) 3-6 6-1 before Russia's Rublev powered past Grigor Dimitrov 7-5 6-2.

Rafael Nadal will meet rising Spanish teenager Carlos Alcaraz in the other semi-final, with live commentary on BBC Radio 5 Live and the BBC Sport website (from 22:00 GMT).
