‘Healthy’ Nadal eyes Wimbledon semis

Rafael Nadal has shrugged off fresh concerns over his fitness as he targets a place in the Wimbledon semi-finals on Wednesday.

The 36-year-old Spaniard played his last-16 clash at the All England Club on Monday against Botic van de Zandschulp with strapping across his abdomen.

Only last month, he won a 14th French Open with his troublesome left foot anaesthetised before undergoing career-saving treatment.

Nadal refused to discuss whether or not his latest physical concern is a worry.

"I'm a little bit tired to talk about my body, all the issues that I am having. I prefer to not talk about that now," said Nadal. "All respect for the rest of the opponents. For the moment I am healthy enough to keep going and fight for the things that I want."

Nadal is halfway to the first calendar Grand Slam by a man since Rod Laver in 1969.

After needing four sets in each of the first two rounds to progress, Nadal has since looked impressive, sweeping past Lorenzo Sonego and Van de Zandschulp to make the quarter-finals for an eighth time.

On Wednesday, he will seek to reach the semi-finals, also for the eighth time, when he faces in-form Taylor Fritz.

The American is in the last-eight of a Slam for the first time and has yet to drop a set. The 24-year-old defeated Nadal in the Indian Wells Masters final earlier this year when the Spaniard was suffering from a cracked rib.
