Kei Nishikori is showing the confidence he has
gained from his coaching arrangement with Michael Chang. The Japanese
No. 1 began his summer hardcourt campaign at Washington over Sam Querrey
6-4, 5-7, 6-4 and says that working with 1989 French Open winner Chang
has boosted his game overall. The winner of 2014 titles in Memphis and
Barcelona said: "I have more confidence now to play the top guys.
""I feel very strong. Physically I'm OK, I had a
great two weeks of training. Everything is ready for the US Open. My
serve is getting better, more strong and more high percentage and also
groundstrokes, I'm a little more aggressive than before. It's a little
of everything. I need to work on a couple more things to get better.
"I'll try to use more forehand, try to step in
more, look to go to the net. We work on a lot of stuff. I'm stronger on
Nishikori, still has to prove himself against
the ATP elite, standing 2-2 against Roger Federer and 1-1 against
top-ranked Novak Djokovic. He is 0-7 in his series with Rafael Nadal.
"I'm happy to be in this ranking situation (but) my goal is not the top
10. Trying to go further," said the No. 11. "The US Open is coming up.
If I could get quarter-finals, semi-finals, that would be great."
