Jessica Pegula came back from a match point down to beat Wimbledon champion Linda Noskova 7-6 (7-2) 4-6 7-5 at the WTA Finals, reaching the semi-finals on Thursday. Noskova had led a break in the third set and held match point on Pegula's serve at 5-4, but could not convert it. Pegula served 16 aces, the most she has hit in a WTA Tour match, while Noskova hit 15 double faults. The win eliminated Coco Gauff, who had earlier beaten Marta Kostyuk 6-4 7-5 despite a lower back problem and fighting back from 5-1 down in the second set. Pegula will face French Open champion Mirra Andreeva in the semi-finals, which will be their first meeting, while Noskova will face Elina Svitolina or Aryna Sabalenka on Saturday.
