Polish top seed Iga Swiatek saw her 25-match winning streak on the Paris clay ended by China's Zheng Qinwen in the Olympics semi-finals.
Swiatek, 23, has won the past three French Opens at Roland Garros, but was beaten 6-2 7-5 by sixth seed Zheng at the same venue.
Losing there for the first time since 2021 was a tough blow for the long-time world number one to take.
Swiatek was visibly upset when she tried to speak to broadcast journalists about an hour after the match and decided not to speak to written journalists - as she is entitled to do under Olympic rules.
