Serena Williams survived another struggle to set up a French Open final against Garbine Muguruza.
The world number one is now within one victory of equalling Steffi Graf's Open era record of 22 grand slam singles titles.
Williams' semi-final against unseeded Dutchwoman Kiki Bertens was more a case of survival of the fittest than a tennis match, with both women appearing far from 100 per cent.
Perhaps that was not too surprising given this was their third match in as many days, and Williams must now focus on recovering for the final on Saturday.
Bertens, who considered not starting the match because of a left calf problem, served for the first set and had two set points but eventually went down 7-6 (9/7) 6-4.
