 “With my set of (health) challenges, it’s a very personal decision.And it’s great that I’ve made the decision that is best for me.”

“I’m really happy that I can showcase my best tennis in these last couple of events, because I think that’s the way I want to go out. 

“I  know everyone has a different way of retiring and ending their career, but for me, I want to try to go out playing my best tennis.”
