And rain continued to fall on Tuesday when the Pole, who was hampered by a right hand injury, dropped 10 straight games either side of another weather delay before exiting to the Bulgarian.

“I’m just so surprised and angry, that, you know, we have to play in the rain,” fumed Radwanska.

“I mean, it’s not a 10,000 tournament. It’s a grand slam. How can you allow players to play in the rain? I cannot play in those conditions.

“I don’t know who allows us to play in those kind of conditions. I mean, I don’t think they really care what we think. I think they care about other things, I guess. So, well, I’m just pissed. I just cannot play in those conditions. I mean, I’m not healthy enough.

Former Wimbledon semi-finalist Pironkova extended her best run in Paris and will face Samantha Stosur for a place in the last four.

“It was very difficult with all the rain, we waited almost three days to finish the match. But I can’t complain, it turned out great for me,” said Pironkova.

Australian Stosur trailed 2014 French Open runner-up Simona Halep 5-3 when their contest was halted on Sunday, but the 21st seed broke the Romanian as she tried to serve out the first set on Tuesday before racing through the tiebreak.

Stosur, who reached the 2010 final at Roland Garros, again broke the sixth-seeded Halep to begin the second set before moving on to the last eight courtesy of a second break.

“Heavy, wet conditions like this don’t typically help me too much, but I think today I was able to use them better to my tennis than [Simona] was and I was able to put her under more pressure,” said Stosur.

Halep, like Radwanska, was critical of tournament organisers, but praised Stosur for handling the “impossible” conditions better.

“It was impossible to play, in my opinion. And to play tennis matches during the rain I think it’s a bit too much,” said Halep.

“But everyone was in the same situation, and who was stronger won today.”
