Anastasia Pavlyuchenkova reached her first grand slam semi-final with a 6-7(2) 6-2 9-7 win over Elena Rybakina.
The Russian came back from a set down and was the more consistent player as she edged out the 21st seed to reach her maiden grand slam semi-final.
Next for Pavlyuchenkova will be Tamara Zidansek on Thursday.
In the first set it was Rybakina who was dominating most of proceedings, with her big serve and effortless hitting causing Pavlyuchenkova problems.
The Kazakh was rewarded for her efforts as she took a 4-1 lead as she opened up the spaces on the court flawlessly.
Back came the Russian in the second half of the set as Rybakina started to produce more unforced errors as well as rushing a lot of her play.
In the end Pavlyuchenkova restored the break deficit and levelled things up at 4-4.
After that both players controlled their aggressive plays and managed to find a bit of consistency.
That was especially important for the 21st seed who seemed to go for a lot more high percentage shots than her Russian opponent as this set would be decided by a tiebreak.
It was a strategy that would pay off as she saved her best tennis for the important moments with Pavlyuchenkova committing a lot of unforced errors.
Rybakina wrapped up the tiebreak 7-2 and took a one set lead after 58 minutes.
Despite that first set, you felt that Pavlyuchenkova’s base level of play was at a much higher level and that was going to stand for her well in the second set.
That is what exactly happened as she managed to create more opportunities with the Kazakh’s level dropping significantly.
A Pavlyuchenkova slip on break point allowed Rybakina to get distracted and miss an overhead smash as the Russian dealt the crucial blow for a 4-2 lead.
Seemingly Rybakina was struggling to find her level from the first set and some nicely constructed points on return from Pavlyucvhenkova saw another break of serve as this match was heading to a deciding set.
In the third set the Russian capitalised on her momentum and took the early break advantage.
However as so often happened in this match the momentum shifted again towards Rybakina with the Kazakh finding her big-hitting range to win three games in a row.
The break lead to Rybakina didn’t last long though as Pavlyuchenkova continued to force some wild errors out of her opponent’s racket.
After that both players were unable to outmanoeuvre each other on return as some effective combinations were produced in effective service holds.
As the match went on, the more clutch both players got as for the second time today a match went to extra innings.
However it was Pavlyuchenkova who applied the most pressure on return and a Rybakina double fault sealed a landmark victory for the Russian.
Tamara Zidansek now awaits for Pavlyuchenkova in what will be her first ever grand slam semi-final.
