Carreno Busta: 'I lost my head, I am very sad'

lost to in five sets, 7-6(8) 6-4 6-7(4) 4-6 6-7 (8-10), after an epic five-hour fourth round match. The point on 8-6 in the fifth set tie-break was a very controversial one as Carreno Bustas ball was initially judged out, then the HawkEye showed it was in and the umpire gave the point to the Japanese.

Obviously Im very sad, no, because after five hours fighting, after five hours match, the way that I leave from the court wasnt correct, and Im so sorry, because thats not mine, said Carreno Busta in press conference.

But I think that the referee missed — the umpire who is near the court missed, and, well, I try to leave faster as possible when I lost that last point, because I know that in any moment I lost the head. But its tough, no, to me to leave Australian Open like this, because I think that I played really good.

I play an unbelievable match. Also Kei, he play really good, and thats sad to leave like this. Carreno Busta is convinced about what he thinks: I dont need to watch the repeat, the replay of the point, because I know clearly that the line umpire calls out.

Then Nishikori make a winner. Obviously the point for Nishikori was so we see. But sometimes the line umpires make mistakes, and thats the game, no?You have Hawk-Eyes. I call the Hawk-Eye. The Hawk-Eye says the ball was good.

And the umpire, I dont know why, but he tried to, I dont know — I dont know why, but he say that the point for Nishikori. If he thinks that the point is for Nishikori, why I can call the Hawk-Eye, you know? If I call the Hawk-Eye and the ball is out, I lost the Hawk-Eye.

If I call the Hawk-Eye and the ball is in, I lost the point. I dont understand. Of course is tough to be focused after this point, but I try to do it, no? Well, the next points, I miss a return just like centimeters. Then Kei plays two good points with my serve.

I also miss from four centimeters a forehand, and, well, he made ace for finish the match. He plays good in this moment. Maybe I distract a little bit, but I just try to continue doing my best. ALSO READ: Rafael Nadal: Worse players than David Ferrer won a Grand Slam title
