“He has so much experience within the tennis business and I’ve long respected his knowledge of the sport. I think it will be great for me to have a new perspective helping me with my game.

“I had a great run with Mike [Sell] and feel I really learned a lot from him throughout the course of our coaching relationship.

“I just thought it was time to try something new, and with Justin I believe I will have a strong, and passionate new voice on my team. In spending some time with Justin throughout the fall I have full confidence that he has a clear vision for my game and an understanding of what I need to do in order to play my best tennis.”

Gimelstob added: “John is a very unique talent, a great guy both on and off the court and I am thrilled to be able to be a part of his team.

“Coaching is in my blood. My father and uncle were both basketball coaches and I had the good fortune of working with some of the best tennis coaches in the world during my career.

“I have the highest regard for the level of commitment coaching a player of John’s pedigree entails. I am excited for the new challenge, and look forward to pursuing it with a player that I believe in so much.

“I have had a great relationship with John for years and think we will communicate really well as player and coach.”
