Thursday French Open Results

Barbora Krejcikova def. No. 17 Maria Sakkari, 7-5, 4-6, 9-7

No. 31 Anastasia Pavlyuchenkova def. Tamara Zidansek, 7-5, 6-3

Krejcikova outlasted Sakkari in one of the best matches of the tournament. 

The Czech had to battle through a match point from the 17th-seeded Greek in the third set to keep the match alive. The French Open does not have a final set tiebreak. 

Krejcikova's most important stretch of the third set came at 4-5. She broke Sakkari's serve to level the set at 5-5 and then held to lead 6-5. 

The players held serve for the next four games, as each of delivered some fantastic shots to stay in the match. The players combined for 58 winners and 13 converted break points in total. 

The final break from Krejcikova came a few points after she could have won the match. The chair umpire overruled an out call on one of Sakkari's returns. Krejcikova made sure the decision did not affect the match by capturing the victory just a few points later. 

The 25-year-old has a pair of Grand Slam doubles championships. Her breakthrough at Roland Garros marked the first time she has got past the fourth round in a singles draw. 

Pavyluchenkova used a run of four straight games to gain a hold on her match with Zidansek. 

The 31st-seeded Russian earned a service break at 6-5 in the first set to avoid a tiebreak and pick up the first set victory.

She followed up on that with a hold and a break to start the second set and immediately answered a Zidansek break to go up 3-1. 

The same situation played out later in the second set. Zidansek broke at 2-4, but she gave that game back right away. 

Pavlyuchenkova's final break of the match allowed her to finish out the contest on her serve. By doing so, she advanced to her first Grand Slam final after six previous quarterfinal appearances. 

The 29-year-old Russian converted on six of her 10 break-point opportunities and earned an edge on second serve, with a 61 percent success rate compared to her opponent's 43 percent on second serve.
