Rafael Nadal is on to the finals of the French Open once again. This time it was under unfortunate circumstances.

On Friday, Rafael Nadal was looking to reach the French Open finals for the 14th time in his illustrious career. Nadal was taking on the third ranked Alexander Zverev in what was expected to be an epic match. The two players had met nine times previously, with the Spaniard winning six of them. Obviously, beating Nadal at the French Open is entirely another animal.

But as the match was playing out, it appeared Zverev was game. He forced the first set into a tie-break. Nadal would eventually win the first set in the tie-break, 10-8. It took some amazing play to win it though.

That didn't shake Zverev though. He continued to battle and the second set also headed to a tie-break. But that's where the match came to an end.

During the tie-break, Zverev was chasing down a forehand from Nadal. He rolled his ankle severely and immediately went to the ground. The fans in attendance at the French Open could hear the screams as he writhed in pain. Zverez would be helped to the locker room. Shortly afterward, he returned on crutches and was forced to retire the match.

Zverez returned to a standing ovation from the French Open crowd. He shook the hand of the chair umpire and then hugged Nadal.

Nadal will now play the winner of the Marin Cilic-Casper Ruud semifinal match. Cilic has the experience advantage but whoever wins that match will certainly be a massive underdog against Nadal.

The all-time great is looking for his record 14th French Open championship and his 22nd Grand Slam title. That would push him two above both Novak Djokovic and Roger Federer for most all-time.
