Halep stays on course

Simona Halep remains in contention to become world number one for the first time after beating Peng Shuai of China in straight sets.

Halep, second in the rankings behind Angelique Kerber, won 6-4 7-6 (9-7).

The Romanian needs to make the semi-finals at least to have a chance of moving to the top of the rankings.

Halep's opponent in the last 16 will be Victoria Azarenka,who beat Britain's Heather Watson to progress.

Former world number one Azarenka of Belarus is making her Grand Slam return at Wimbledon after giving birth in December.

Germany's Kerber, meanwhile, plays American Shelby Rogers for a place in the last 16 on Saturday.

If Halep does reach the last four then Kerber needs to repeat her 2016 run to the final to retain hope of staying top of the rankings.

New territory for French Open winner

Jelena Ostapenko continued her recent good form by reaching the last 16 at Wimbledon for the first time.

The French Open champion beat Camila Giorgi 7-5 7-5 to set up a meeting with Elina Svitolina, the Ukrainian fourth seed who beat Carina Witthoft 6-1 7-5.
