G’day from Wimbledon,
It’s been a lot of fun this year to take traditional static match data – such as 1st & 2nd serve points won – and do something more with it this year at Wimbledon.
Traditional match data relies on basic PDF reports where match data sits in isolation from other matches. The match data does not communicate with other data points that often appear on the very same page. My new AI Tennis Data Dashboard centralizes every match, player, and stat in one place with instant navigation at your fingertips.
Also, hats off to IBM for upgrading their match data this year as well. We are all trying to push the envelope and find match metrics that tell a better story and more accurately describe what happens in a match.
Which brings me to this morning. I just found a data point that stopped me in my tracks. Let’s start with the men’s draw.
MEN 2026 Wimbledon – To Qtr Finals
MEN: 1st Serves
- 1st Serves Pts Won = 74%
- 1st Serve Pts Won / Return In Play = 56%
This is great news for the returner. If you can get the first serve back in play, you have a 44% chance of winning the point. That’s a huge deal and a nice jump from only winning 36% against all first serves, which would include aces and return errors. This makes me want to go and work on my slice return to make sure I can DEFEND against strong first serves and float them back into play. At least you are in the point, and at least you have moved up in the world from winning 36% to 44%. That’s the kind of data we need more of!
Jannik Sinner has won 69% (89/129) of points behind his first serve when the return comes back in play to the quarter-finals. He backs up a strong first serve with clean, efficient power groundstrokes that keep him ahead in the point.
Now, let’s take a look at what happens when the point starts with a second serve.
MEN: 2nd Serves
- 2nd Serve Pts Won = 51%
- 2nd Serve Pts Won / Return In Play = 45%
This is shocking. This stopped me in my tracks. We all need to slow down and absorb just how important this data really is. Second serves are essentially an even battlefield – even on the serve-friendly grass courts at SW19.
But the news gets even better for returners. If you put the second serve return in play, you now have an impressive 55% chance of winning the point. Tipping the scales that much in just one match metric is enough to win a substantial amount of matches over a season.
Taylor Fritz (60%) leads the pack of players who are still alive in the draw with second serve points won when the return comes back.
WOMEN 2026 Wimbledon – To Qtr Finals
WOMEN: 1st Serves
- 1st Serves Pts Won = 66%
- 1st Serve Pts Won / Return In Play = 51%
The women are winning two out of three first serve points so far at The Championships. That’s a normal number compared to recent years. But when you strip away aces and return errors and only focus on returns in play, the win proportion basically drops to an even battlefield.
That’s crazy and should lead to a flood of women’s players working on their defensive first-serve returns, focused on blocking and putting the return back in the court at all costs. Naomi Osaka leads the women’s draw in this specific statistic, winning 67% (55/82) of first serve points when the return is put back in play. Karolina Muchova is not far behind, winning 65% (64/99).
WOMEN: 2nd Serves
- 2nd Serve Pts Won = 47%
- 2nd Serve Pts Won / Return In Play = 42%
Everything about the second serve is bad news on the women’s tour. The ladies are winning only 47% of second-serve points (underwater) at Wimbledon this year. And when the return is put back in play, the win percentage plummets further, to 42%. It’s so tough to win a match when you are doing so poorly behind your second serve. Muchova is winning a sizeable 60% of points (43/72) behind her second serve when the return comes back into play.
SUMMARY
This data screams to coaches and players the need to work on a strong DEFENSIVE return, with a primary focus on putting more returns back in play. The return could be high and floating, or blocked back hard and low. It doesn’t matter. Give yourself the opportunity to break by putting one more return of serve back in play.
And the other side of the coin is to make sure you are not beating yourself by missing too many first serves. First serves in play protect the second serve and keep the overall win percentages higher.
Lastly, about the worst thing you can do is hit a second serve return in the net. Missing second serve returns is bad enough. But putting it in the net does not give you a chance at all to feast on second serve return points.
