Andreeva has now won three straight matches against Swiatek, having also triumphed in Dubai and Indian Wells last year, after she earned a 3-6 6-4 6-3 comeback win in two hours and 36 minutes.

Swiatek recovered from a break of serve in the first game to quickly pull level at 2-2 before surviving a six-deuce game to hold for 3-2 on her way to taking the first set.

Andreeva did not let her level drop, though, and held her nerve as the pair traded breaks early in the second before forcing a decider with a brilliant forehand return winner on set point.

Although Swiatek broke first in the third set, Andreeva took total control while 2-0 down and reeled off five straight games before converting her second match point attempt.

"I was just trying to be fearless," Andreeva said in her on-court interview.

"I was trying to go for my shots because I know when I'm getting tight, I tend to just put the ball in… just waiting, praying for the opponent to make a mistake.

"And I knew that against someone like [Swiatek], it was never going to happen. So, I was forcing myself to finish the match on my own."

Andreeva will face Rybakina in the semi-final, with the Kazakh overcoming an early scare to win her quarter-final in three sets.

Despite losing a first-set tie-break to Leylah Fernandez, Rybakina triumphed 6-7 (5-7) 6-4 7-6 (8-6) in a little more than three hours.

Fernandez wasted three set points before eventually going on to clinch the opening set, but Rybakina looked more confident in the second as she forced a decider.

The Canadian looked set to cause an upset after taking a 4-2 lead in the third set, but Rybakina fought back to win the tie-break and book her place in the final four.
