'We gonna check later': Tricky question stumps Nadal

Rafael Nadal is bulldozing his way through the Australian Open but the Spanish top seed isn't trying to compare his form to any tournaments past.

Well, it's not that he's not trying -- it's just pretty hard.

The world No.1 demolished Bosnian 28th seed Damir Dzumhur for a 6-1 6-3 6-1 triumph at Margaret Court Arena on Friday night.

But even when it takes just one hour and 52 minutes to reach the fourth round, it can be difficult to gather your thoughts.

Nadal was quizzed in the on-court interview about his tremendous form as he bids to reach a second consecutive final in Melbourne, and the answer didn't go too well.

"You dropped three games in the first match, you dropped 13 in the second round and then just five tonight," began the question.

"Is that one of the best preparations you've had going into the fourth round for a grand slam?"

The Spaniard, who played no lead-up tournaments as he managed a knee injury that first hit late last year, didn't take long to

"I really don't know," he said with a hearty laugh from himself, the crowd and the interviewer.

"That's -- we gonna check later! But the most important thing is I am in the fourth round. That's all, it doesn't matter the way."

Nadal did take in a variety of exhibition matches across Australia after pulling out of the Brisbane International.

And the results are seemingly backing his tweaks.

"I didn't think about (expectations) when I arrived ... I needed hours of court, hours of practice, hours of playing sets with different players," Nadal said.

"That's what I did. I think I did a good preparation here. I felt myself playing well. That's all.

"Here I am. I am in the fourth round. That's because I am doing the right things. Let's see how far I can go."

Nadal said he would have to be at his best to get past No.24 seed Diego Schwartzman, a quarter-finalist at last year's US Open, in the next round on Sunday.

"He's a great player. He had an amazing last year, and he's started again this year playing so well," Nadal said of the Argentine.

"He's won three matches here, playing at very high level. He's a very complete player. He's a player that if I don't play my best, probably I am not going to win. Tough one."
