Nishikori lost out 6-4, 4-6, 2-6 in the end to his opponent who trains at the same Florida academy; and while admitting he wasn't at his best; he will look to play even better next time out as he aims to build fitness.

“I was not 100 per cent, but I was happy with the way I played,” said Nishikori.

“I was not fit enough and maybe if I finished in two sets it would have been different, as I had some chances. It’s a shame, as I could have won today, but it was a good moment and I’m positive today. I was hitting the ball better in the altitude, so it wasn’t easy, but I do like it. I’ll try to be better prepared for next week.”
