A severe weather warning forced the rollercoaster semi-final between Novak Djokovic and Andy Murray into a Saturday shootout.
World number one Djokovic was leading 6-3, 6-3, 5-7, 3-3 when play was halted at 1833GMT with the match officially called off 10 minutes later.

When play was stopped, Djokovic and Murray, meeting for the 27th time, had been on Court Philippe Chatrier for 3 hours and eight minutes.
Top seeded Djokovic, who knocked out nine-time champion Rafael Nadal in the quarter-finals, needs a French Open title to make him only the eighth man to win all four majors.
It would also put him halfway to a rare calendar Grand Slam, a feat achieved by just two men, most recently by Australian great Rod Laver back in 1969.
Murray is hoping to become Britain's first men's finalist since Bunny Austin in 1937.
Djokovic swept through the first two sets as he sought an eighth successive win over Murray and his 28th in a row this season.
But Murray clawed his way back, taking the third set and forcing the Serb off court for a medical timeout.
In fading light, Murray broke for 2-1 before Djokovic hit back immediately at 2-2. Moments later, the match was called off and will resume at 1100GMT Saturday before the women's final between Serena Williams and Lucie Safarova.
