Djokovic has hit 47 aces in his first three matches; the most he has hit in the first three rounds of any Grand Slam in his career; with 17 coming against the Japanese ace; it is something that the Serbian is glad to have in his arsenal going forward.
This will especially be needed when he faces Diego Schwartzman in the next round. He is known as one of the best returners of the ball; he could prove a match for the defending champion.
“I think in terms of service rhythm that I have at the moment, winning percentage from the first serves is really high,” Djokovic said after his third-round win against Yoshihito Nishioka.
“So that's probably as best as my serve can actually be in the moment, which I'm very pleased with. It allows me to go quicker through my games and win more dominantly my service games and put additional pressure on the service games of my opponents. That's definitely something that's useful going towards the second week of the Grand Slam."
