Kei Nishikori speaks to the media after the 6-4, 7-6(3), 3-6, 6-3 defeat against Roberto Bautista Agut

Q. Do you put today's loss more down to your opponent playing well or you not playing well?
KEI NISHIKORI: I think both. I couldn't maintain my level high enough, you know, to beat Bautista today. I think he served well every set. Was really tough time having my return game.

I had many chance, but I think he played well the important points. Yeah, I think mix of both.

Q. Do you think you could have been more aggressive?
KEI NISHIKORI: Well, yeah.

Q. Would it be fair to say that grass is your least favorite surface to play on?
KEI NISHIKORI: Well, yeah. It's not easy. I don't have, you know, good result on grass. Yeah, got to work on every year.
