"The amount of work I put in and I'm still having so much discomfort in my wrist": Nick Kyrgios open on crying after Indian Wells retirement

Nick Kyrgios was open on why he was so emotional after his Indian Wells return turned to nightmare after he retired with discomfort in his wrist against Botic van de Zandschulp.

Kyrgios continues to be blighted by injuries and whether he would even play in California was a mystery. Especially after issues in training earlier in the week.

He took to the court and played some good tennis but as he said himself, the biggest heartbreak came with the fact that he played well but then was suddenly blighted by injury.

Speaking afterwards, he mused on why he cried on the bench after he had to retire. He said it was as it looked and that it was due to the amount of work that he had put in to get back and how it was suddenly taken away.

"It's just more so I guess the amount of work I've put in to get back, and just to know that it's not -- like, I can play some, there are glimpses of some really good tennis that I can still play. I guess this process has been probably one of the biggest challenges I've faced in my life. Reality, it's not too bad, but for my tennis career, it's by far the biggest," said Kyrgios.

"Yeah, just the amount of work that goes in when I go back home or when I'm not playing, it's not fun. I know that I can't really be doing any more to try and get back and play. It's just like the process of, even if I lose that match, I don't want to like, I don't mind losing if I don't feel, you know. I know it's going to be uncomfortable but I don't want to feel the pain I was feeling. I'm okay to lose a match. I've lost matches in my career many times. I guess it's just the amount of work I put in and I'm still having so much discomfort in my wrist. That's I guess why I got a bit emotional towards the end because it's one of my favorite tournaments.

"You know, even after Australian Open I wasn't sure what I was going to play next, but this was always probably going to be one of the tournaments I'm going to play regardless. I love it here. I've had so many good memories here. It's one of the best tournaments we have. After Australian Open, all I did was rehab, train, and then try and get ready for this tournament. I was two days out of the tournament here and I was having a great training session, and literally the second-to-last point in my training session I hit a forehand, I felt a sharp pain, and I had to stop playing.

"I mean, it's not ideal, but I guess, I don't know, we go back to the drawing board as a team, and we just try and figure out and navigate a way to just get through these matches. Like, I would have loved to be able to finish that match even if I lose just as a building block, to say, okay, I went out there and was competing with a very good player, and I had chances and set points and breakpoints. So it's like these building blocks, but now if I'm not finishing matches that becomes a concern.”
