Jannik Sinner on Centre Court after beating Shintaro Mochizuki to reach quarter-finals:

"He's an incredible player - coming from qualifiers and playing such a high level for such a long time - I wish him all the best and he should be proud of himself.

"His game suits this surface very well but I tried to stay more aggressive.

"I'm very happy about my performance - I'm trying to step up a little bit more every day."

On playing Jan-Lennard Struff next: "He's a very aggressive player, big big server - it's most important for me to rest now, but I have big respect for him."

Coco Gauff committed just eight unforced errors in that set compared to 24 in the first.

And although she still came up with two double faults - one that was almost very costly when serving for the set - it was a marked improvement from the six double faults she picked up in the opening set.
