Jannik Sinner defeated Novak Djokovic, 6-4, 6-4, 6-4, in the Wimbledon semi-finals.
Just as he did 12 months ago, Sinner beat the 24-time Grand Slam champion in straight sets to reach the Wimbledon final.
Who will win the Wimbledon final? Jannik Sinner or Alexander Zverev
The top two seeds collide!
But what was the Italian working on in training before his latest win over Djokovic?
Serena Williams’ coach, Rennae Stubbs, has now answered that very question.
Rennae Stubbs saw Jannik Sinner practising his serve for ’30/40 minutes’ before beating Novak Djokovic
Stubbs shared the following message on X.
“Was on the practice court yesterday next to Jannik [Sinner] and he must have served for a minimum of 30/40 minutes,” she said.

“It’s obvious that he knew how important the serve was today.
“He’s reaping the benefits of that work.
“You don’t get great by being lazy and not having the attention to detail to win.”
Practice paid off for Sinner as he produced a stellar serving performance in his three-set victory over Djokovic.
Jannik Sinner’s serving stats vs Novak Djokovic
- Aces – 16
- Double faults – 0
- 1st Serve % – 63%
- Win % on 1st Serve – 88%
- Win % on 2nd Serve – 62%
16 aces, no double faults, winning 88% of his points behind his first serve, Sinner couldn’t have asked for much more.
The question is, can he maintain that level for the final, where he will take on another big server, Alexander Zverev?
Like Sinner, Zverev has been praised at length for his serving prowess at this year’s Wimbledon Championships.
But of the two finalists, who has actually been the better server throughout the tournament?
Who has served better at Wimbledon this year – Jannik Sinner or Alexander Zverev?
Looking at the numbers both players have produced, it’s no surprise that they have made the final.

Alexander Zverev’s serving stats at Wimbledon (2026)

| 1R vs Alexander Blockx (Four sets) | 21 | 7 | 83% | 78% | 82% |

| SF vs Arthur Fery (Three sets) | 9 | 2 | 75% | 78% | 89% |
However, when assessing their averages throughout the tournament, it’s tough to decipher who has truly been the better server.
How the Wimbledon finalists compare on serve
| Player | Aces | Double faults | 1st Serve % | Win % on 1st Serve | Win % on 2nd Serve |
| Jannik Sinner | 19 | 3 | 66% | 85% | 60% |
| Alexander Zverev | 15 | 3 | 75% | 80% | 74% |
Sinner served more aces than Zverev and won more points behind his first serve.
But Zverev had a higher first-serve percentage and won more second-serve points.

The likelihood is that Zverev’s serving numbers won’t be quite as strong in the final, taking on arguably the greatest returner in the men’s game.
But if he is to stand a chance of causing the upset, he can’t afford to let his serve fall apart as it has at points throughout his career.
If the double faults start flowing, it’s tough to see a way for Zverev to clinch the title.
Whatever happens, the serve will be crucial for both players in Sunday’s final.
