"I want to encourage children with diabetes, to never give up on their dreams no matter what others might say to you," he said in an announcement.

While Rafael Nadal has confirmed he plans to try to play Wimbledon, a few other names have been announcing their withdrawals from the grass-court Grand Slam.

The best players recognize that they have no precious energy of any kind to waste in the throes of a competitive five-setter.

For the first time since November 2003, none of the Big 3 are in the Top 2. Also, Casper Ruud cracks the Top 5.

The third-ranked German sustained the injury during his French Open semifinal against eventual champion Rafael Nadal.

The world No. 3 is set to fly back to Germany on Monday for further evaluation and treatment of his ankle, according to a post shared on social media.

By showing concern for injured Alexander Zverev, the 21-time Grand Slam champion displayed a level of humanity too often missing at all levels of the game.

The 21-time Grand Slam champion is 13-0 in French Open finals.

Nadal is coming off of a great performance against Novak Djokovic, but his health is always a question mark, and Zverev is a worthy opponent.
