Six times the 29-year-old had lost at the quarterfinal stage of one of the four Majors, but she used all her experience to overcome her doubles partner in a gruelling scrap.

Rybakina, 21, looked in control of her first Grand Slam quarterfinal when she opened up a 4-1 lead in the first set but Pavlyuchenkova hit back to force a tiebreak.

Pavlyuchenkova took the momentum into the second set to level the match and kept her nose ahead in a tense finale.

Rybakina, who beat Serena Williams in the fourth round, held serve three times to stay alive in the third set.

But she failed at the fourth time of asking, ending the contest in tame fashion with a double-fault.

Pavlyuchenkova will face fellow semifinal debutant Tamara Zidansek for a place in Saturday’s final after the Slovenian also came though a long battle, against Paula Badosa.
