Rafael Nadal reached his 13th Roland Garros semi-final early on Wednesday with a straight sets win over Italian teenager Jannik Sinner but claimed it was "dangerous" to finish at 01:30 in the morning when the temperature had plummeted to 12 degrees (53F). Nadal, the 12-time champion, defeated Sinner 7-6 (7/4), 6-4, 6-1 to clinch a 98th victory in his 100th match at the French Open.

Schwartzman stuns Thiem

He will next face Diego Schwartzman, the Argentine who defeated third seed Dominic Thiem 7-6, 5-7, 6-7, 7-6, 6-2 in a five-hour epic on Tuesday for his first ever Grand Slam Last-4 appearance. However, Nadal was unhappy with organisers who scheduled five matches on the main Court Philippe Chatrier. "I know footballers play under these conditions, but they are all the time moving," said Nadal after the latest ever finishing match at the tournament. "We stop, we come back, we stop on the changeovers. I think this is a little bit dangerous for the body with these very heavy conditions."
