The 1.67-metre tall Belgian, who won four French, two US and one Australian Open title, and reached the Wimbledon final twice, was back at the All England Club on Tuesday to receive her International Tennis Hall of Fame ring, after being inducted into the ITHF in 2016.
For Williams, it is her ninth Wimbledon final as she goes for her sixth win.
The vital break in the second set came in the fifth game, Kuznetsova netting for 0-30 on her serve, then overhitting for 15-40 under the pressure of Muguruza's consistent returns and cursing herself.
