Rafael Nadal continued his clay domination on Friday, rallying from a set down to reach the Italian Open semi-finals with a 4-6, 6-1, 6-2 victory over Fabio Fognini.

The world number two needs to lift an eighth career title at the Foro Italico on Sunday to return to the top of the ATP rankings after losing that position to Roger Federer last week.

Spaniard Nadal dropped the opening set in an hour but re-grouped effortlessly as he swept past the Italian in the one-sided second and third sets of their quarter-final tie.

“I’m not used to playing so early,” Nadal said of his midday start. “But I’m very happy to be in the semi-finals.

“This was a very important win for me today.”

Nadal also beat Fognini in Rome in 2013 in their first ever meeting.

This was his 11th victory in 14 meetings with the 21st-ranked Italian, and sixth in a row.

It was the first time in four years that Nadal managed to win his quarter-final tie in Rome and next up he will face either fellow former world number one Novak Djokovic or Japan’s Kei Nishikori.

Sharapova battles past Ostapenko

Maria Sharapova fired a French Open warning with an epic three-hour win over Roland Garros champion Jelena Ostapenko to reach the semi-finals.

Former world number one and five-time Grand Slam winner found herself in a dogfight with her Latvian opponent.

Playing her fourth match in as many days, Sharapova needed three hours, 10 minutes to win a gruelling struggle, eventually triumphing 6-7 (6/8), 6-4, 7-5.

For Sharapova, now the world number 40, it was arguably her best victory since her return from a 15-month doping ban last year.

The loss, meanwhile, left Ostapenko with only Rome and Stuttgart quarter-finals to show for her efforts prior to the start of her title defence in Paris a week from Sunday.

Sharapova rode a roller-coaster in her marathon win, working her way from 4-1 down in the first set only to drop it in a tiebreaker after 80 minutes.

She regained her momentum to win the second set but it was tough in the third when she let a 4-2 lead get away.

With Sharapova serving for victory, Ostapenko secured a break for 4-5 thanks to a ninth Sharapova double-fault which yielded a break point.

The sixth seed then saved two Sharapova match points to level 5-5 before the Russian secured victory two games later with a final break in a match marred by 21 cumulative double-faults and a dozen breaks of serve.
