Alexander Zverev booked his place in the fourth round at Wimbledon on Saturday, beating Marcos Giron in straight sets.
What happened?
The German tennis player won the match 6-2, 7-6, 6-4, and was praised for the speed of his serve.
He served 17 aces and had the fastest average serve at the tournament so far at 132 miles per hour.
Why it matters for Alexander Zverev
Zverev's Wimbledon run comes after he finally ended his wait for a first Grand Slam title in June, beating Flavio Cobolli in the final at Roland Garros.
The 29-year-old felt different from last year, saying he plays better tennis and has more confidence.
What comes next?
Zverev will now take on Jiri Lehecka, the 13th seed, who has dropped just one set so far at the Championships.
He wants to keep going and play a lot more great matches, enjoying his time on court.
Zverev's reaction to Annabel Croft's kind words about his serve was humble, saying normally when people tell him these kind of things it always goes backwards.
But he is determined to serve at 133 miles per hour next match on average, to keep his momentum going.
The world No. 3 saw off the challenge of Alexander Blockx and Valentin Royer before beating Giron.
He feels like he has a bit more confidence, which is always very helpful, especially on a grass court.
Zverev suffered a first round exit to Arthur Rinderknech in 2025, but this year he is playing better tennis.
He just hopes to continue doing that and winning, coming into Wimbledon with a title like the one in Paris helps everybody.
The German tennis player is through to the fourth round and wants to keep going, playing a lot more great matches.
