Maria Sakkari had no issues in her last WTA Finals group stage match against Ons Jabeur, cruising through to the final-four with a 6-2 6-3 victory on Friday.

Sakkari needed only 69 minutes for the straight-sets win, making it her third straight-sets triumph in the Nancy Richey Group after also blowing past Aryna Sabalenka and Jessica Pegula.

Greece's Sakkari took advantage of some wastefulness from Jabeur, with the Tunisian posting 19 unforced errors with just eight errors. Her efficiency did not improve in the second set, managing only three winners with 12 unforced errors.

Sakkari's serve was a weapon throughout, landing 70 per cent of her first-serves fair and converting 82 per cent of those chances (27-of-33) into points.

Jabeur could have advanced through to the next round with a win, but instead Aryna Sabalenka will advance with Sakkari out of the Nancy Richey Group.

The only other player yet to lose a set in the tournament is Iga Swiatek in the Tracy Austin Group – who has only played two matches so far.
