Beatriz Haddad Maia produced a stunning comeback to defeat Ons Jabeur 3-6 7-6(5) 6-1 to reach the semi-finals at Roland Garros.
The Brazilian was outplayed for most of the first two sets but ultimately took advantage of an erratic Jabeur.
Too many unforced errors from Jabeur in the third set spoiled an extremely impressive first set and three quarters for the Tunisian.
Haddad Maia now awaits either world number one Iga Swiatek or Coco Gauff in the last four.
The match was split into two halves with Jabeur dominating the first half with an impressive first set.
Jabeur was extremely efficient on serve and used her slice to set up effective winners with Haddad Maia having very little answer to the 14th seed.
The Tunisian broke twice in the opening stages but was broken for a second time in the seventh game as Haddad Maia continued to remain consistent on return.
However Jabeur continued to use her forehand to force Haddad Maia out of position as the seventh seed broke in the eighth game and wrapped up the opening set in 44 minutes.
In the second set Jabeur was flawless on serve, holding to love on four occasions as she looked supremely confident in her baseline play.
Tennis is a strange sport though and it’s all about quality not quantity and about when you are producing your best tennis not for how long.
That was the case as Jabeur had two break points to serve out the match but was too passive and produced a flurry of errors.
Haddad Maia held and never looked back as in the second half, was far the better player as she forced a second set tiebreak.
The Brazilian stormed to a 5-2 lead in the tiebreak and a stunning forehand winner down the line sealed the second set.
From there Jabeur was all over the place with her decision-making and committed the simplest of unforced errors.
As a frustrated Tunisian slammed her racket in frustration, Haddad Maia took full advantage hitting winners from both sides with ease as she secured six of the seven games to secure victory.
A stunned Haddad Maia was in shock as she couldn’t believe her luck as she enters a first Grand Slam semi-final.
Next for Haddad Maia will be either be world number one Iga Swiatek or Coco Gauff in the last four on Thursday.
