Serena Williams survived a major scare before sealing her 11th Wimbledon semi-final appearance as the seven-time champion hit back to beat Italy's Camila Giorgi 3-6, 6-3, 6-4 on Tuesday. The highest seed left in the draw, 11th seed Angelique Kerber had an easier time with a 6-3, 7-5 win over Russian 14th seed Daria Kasatkina.

Kerber is bidding to win the Wimbledon title for the first time after losing the 2016 final to Serena Williams.

Williams was in danger of a stunning quarter-final exit after world number 52 Giorgi became the first player in this year's tournament to take a set off the former world number one.

But Serena bludgeoned her way out of trouble over the final two sets to stay on course for an eighth All England Club triumph.

The 36-year-old will play German 13th seed Julia Goerges on Thursday for a place in Saturday's final.

Goerges advanced to the Wimbledon semi-finals for the first time with a 3-6, 7-5, 6-1 win against Dutch 20th seed Kiki Bertens on Tuesday.

Goerges had suffered five successive opening round defeats at the All England Club before this year.

Kerber, who won the Australian and US Open titles in 2016, plays former French Open champion Jelena Ostapenko on Thursday for a place in Saturday's final.

Ostapenko became the first Latvian woman to reach a Wimbledon semi-final as the former French Open champion beat Dominika Cibulkova 7-5, 6-4.

The 12th seed hasn't dropped a set in her first five matches.
