World number one Rafael Nadal is on course for an 11th French Open title after he dispatched Argentine 11th seed Diego Schwartzman in their quarter-final clash.

Top seed Nadal, 32, trailed 6-4 3-5 when rain halted play on Wednesday but he turned it around by beating his opponent 4-6 6-3 6-2 6-2 to stay on course for a record-extending 11th title.

After the match, Nadal confessed that he was a “bit lucky” the match was halted by rain.

He said: “I was able to stop, to think, to calm down and to see things a bit with more clarity.”

The Spaniard will now face fifth seed Juan Martin del Potro in Friday’s semi-final after the Argentine saw off third seed Marin Cilic 7-6 (7-5) 5-7 6-3 7-5 in another last eight clash that was moved to Thursday because of rain.

The winner will face either Austrian seventh seed Dominic Thiem or unseeded Italian Marco Cecchinato in the final on Sunday.
