You need to have change when you feel something isn’t right. When you have a concept in your head of how you want to do something and it doesn’t match up, then it’s tough to collaborate with someone and it’s tough to perform on court.

“I’ve gone through various changes in my career so far, a lot of coaches. I’m not going to hide that, it’s obvious. You’ve got to search for the right thing and hope that next time it’s going to be better. I’ve got no hard feelings and for me it’s just another chapter of my life. It’s not easy, but it’s something new and fresh to look out for.”

• Kamakshi Tandon of takes a closer look at the only two North American Hispanic players in the top 100: Monica Puig and Christina McHale.

"It makes me feel really special that I'm able to play tennis for the island and just be recognized as a top figure over there," Puig said. "I'm out on the streets, and people will stop me and say, 'Can I have your autograph/ Can we take picture with you?'

"In Puerto Rico, since the sports are very big, I'm a pretty big public figure over there. And it's kind of nice, because it shows that people are paying attention to what you are doing and there's a lot of people who support you."

McHale's Hispanic connections are not quite as well-known but remain personally significant for the 21-year-old.

"The Cuban culture has been a big part of my upbringing," she told "I love Hispanic food. Especially I love when my grandma cooks Cuban food. Whenever I'm away for a long time at a tournament and I come back, I always want my grandmother to cook me Cuban food like rice and black beans.

" And my grandmother loves to watch novellas, so if I go over to her house, she'll always have Spanish shows. I sit with her and I'll watch."

When asked if the change of thinking was due to the Troicki affair, Miller added: "I think it's fair to say that the Troicki case highlighted the issue.
