Here, PA recalls Williams’ route to the final.
Williams was given a gentle opener against the Italian qualifier and she got a good work out in a 6-4 7-5 win.
One of the biggest shocks in Wimbledon history was on the cards as Williams lost the first set to the 18-year-old, but she came back to triumph 2-6 6-2 6-4 in front of the watching Duchess of Sussex.
In a repeat of last year’s semi-final, Williams again got the better of the German, posting a 6-3 6-4 victory.
Williams kept up her 100 per cent record against Navarro with the easiest of victories, dropping just four games in a 6-2 6-2 win.
Williams’ toughest test was against world number one Ashleigh Barty’s conqueror Riske in the last eight and she looked to be in trouble as she was a break down in the final set. However, she rallied to win 6-4 4-6 6-3.
The wily Czech was no match for the power of Williams in a one-sided match that she dominated from the start, triumphing 6-1 6-2.
