Agnieszka Radwanska and Simona Halep accused the French Open of not caring about the players after both women were knocked out in the fourth round after being made to play in the rain.
Radwanska led Tsvetana Pironkova by a set and 3-0 when play was halted on Sunday, but lost 10 games on the resumption and was eventually beaten 2-6 6-3 6-3. She said a previous hand injury meant the heavy conditions made it impossible for her to play her game.
"I had surgery a few years ago and I couldn't really play in those conditions, end of story," said the second seed.
"I'm just so surprised and angry that we have to play in the rain. I mean, it's not a 10,000 tournament (the lowest level of professional tennis). 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 these kind of conditions. I don't think they really care what we think. I think they care about other things, I guess."
Halep had led Sam Stosur 5-3 on Sunday but, like Radwanska, was on the back foot from the start yesterday and went down 7-6 (7/0) 6-3.
The sixth seed and 2014 finalist said: "I cannot comment about the conditions, I have no words. It was impossible to play, in my opinion. And to play tennis matches during the rain, I think it's a bit too much.
"No one cares about the players, in my opinion.
"I don't care that I lost the match today, but I was close to getting injured with my back, so that's a big problem.
"But, like I said, no one cares. We have just to go and play," she added.
