Sidelines

Federer wonder shot not that great, jokes Kyrgios

-- Roger Federer eased past Nick Kyrgios 6-4, 6-1, 7-5 in a match which included an unlikely forehand, flicked from near the ground around the net post that Kyrgios couldn't believe.

But the Australian jokingly played down the shot after the match despite his wide-eyed admiration on court.

"I was trying to tell him that the shot wasn't that good! No, it was almost unreal. Almost got to the point where I wanted him to start making shots like that, and I finally got it. I was pretty happy with myself."

A little compulsive

-- John Millman, who will face Federer for a place in the quarter-finals, admitted he was a handful for his parents when he was growing up in Brisbane.

"When I was 12, I was crazy. I think I was super, super OCD, and I tried to kind of wipe that away. I don't want to go back to when I was a little kid. I was really in my head back then. I was probably embarrassing my mum and dad and sisters too much, and they kind of stamped that out," said the Australian.

Feeling tall being short

-- Dominika Cibulkova, who measures up at 5ft 3ins (1.60m), has found a soulmate in tennis's land of the giants in men's player Diego Schwartzman who is just 5ft 7ins (1.70m).

"I respect him a lot, because for me, it's very challenging to play the best tennis against all these tall girls. On the men's side, I cannot even think about returning John Isner (6ft 10in/2.08m) or Kevin Anderson (6ft 8ins/2.03m) or somebody like this. He has my respect," said the Slovakian who made the last 16 on Saturday by knocking out Wimbledon champion Angelique Kerber.

Who's saying what

"Well, now I feel like I have eaten 500 bagels with smoked salmon on them."

-- Naomi Osaka when asked about her pre-match superstitions

"I don't care because I'm just taking care about my draw, about my opponent, about my matches, and my day."

-- Angelique Kerber not interested in why she and top two seeds Simona Halep and Caroline Wozniacki all failed to make it past the third round.

"I lost."

-- Alexander Zverev when asked what happened in his defeat to Philipp Kohlschreiber

"I fight until my last T-shirt."

-- Kohlschreiber

"I don't know what anything has to do with Madison and my match."

-- Kiki Bertens who lost to Marketa Vondrousova after being asked if Madison Keys can reach the final for a second successive season.
