In-form Nick Kyrgios fires ominous warning to rivals ahead of Wimbledon

Nick Kyrgios thundered 32 aces at Feliciano Lopez at Queen’s before declaring his serve can still improve.

The Australian, who is into the semi-finals, set a new record for aces served in a two set match en-route to his 7-6 7-6 win.

Kyrgios could jump to 12th in the world rankings ahead of Wimbledon should he win at Queen’s, and he believes his serve can get even better.

“I’m always looking to improve my game,” Kyrgios said.

“Obviously I think serving was one part of my game that didn’t have much improvement [left]. Obviously I was wrong.

“I still think I can serve better. There were some periods [against Lopez] where I missed a lot of first serves in a row. It’s easy to have 32 aces and just walk away. It’s a lot of free points, which is good on the grass.

“My serve’s been like this ever since I was a little kid. It was my best shot. I always based my game around it.

“It was one shot where I didn’t really practice much at all.”
