Serving on grass: what 40,000 WTA matches show before Wimbledon 2026

Grass has a reputation: it rewards the serve. Before Wimbledon 2026 gets under way, we wanted to know whether the numbers back it up, or whether it is just a commentator’s cliché. The short answer: the data is unambiguous. On grass, the serve weighs more than on any other surface on the WTA tour, and the gap is measurable to the point.

This study draws on nearly 40,000 WTA singles matches since 2015, surface by surface, service point by service point. The full method is at the bottom of the page.

The serve dominates more on grass than anywhere else

The clearest measure is the share of service points won by the server. Across all WTA matches since 2015:

• Grass: 58.5% of service points won
• Hard: 56.2%
• Clay: 54.2%

The order follows surface speed exactly, from slowest to fastest. Between clay and grass, the server wins more than 4 extra service points per 100. Over a match, that gap moves whole games: it makes breaks rarer, set finishes tighter, and gives the returner far fewer windows to turn a match around.

That is the structural reason grass produces different matches. It is not a feeling, it is a clear shift in the serve-return balance.

The ace, grass’s signature weapon

If the serve dominates more, it is partly because it becomes unplayable more often. In aces per 100 service points:

• Grass: 4.57
• Hard: 3.90
• Clay: 2.54

On grass, there are roughly 80% more aces than on clay. The low bounce and the pace of the surface turn well-placed first serves into outright winners, where the same ball would come back into play on clay.

And that added risk does not come at a heavy cost: the double-fault rate is steady across surfaces (around 5 per 100 service points, slightly lower on grass). In other words, the serving gain on grass is clean, not paid for with more errors.

The biggest serves on grass

Not everyone benefits from grass the same way. Isolating players active in 2024 and 2025 with at least 30 grass matches since 2015, here are those who win the highest share of their service points on the surface:

Player	Service points won	Aces / 100
Petra Kvitova	64.3%	8.3
Elena Rybakina	63.6%	9.6
Beatriz Haddad Maia	63.5%	4.5
Madison Keys	63.4%	8.0
Karolina Pliskova	63.3%	10.7
Iga Swiatek	63.3%	5.0
Angelique Kerber	62.3%	2.7
Ekaterina Alexandrova	61.9%	9.5

The list reads like a grass honour roll: Kvitova, Rybakina and Kerber are among the most recent Wimbledon champions. Karolina Pliskova posts the highest ace rate in the group (10.7 per 100 service points), a pure-server profile alongside Rybakina and Alexandrova (around 9.5). At the other end, players like Kerber or Haddad Maia hold serve without leaning on the ace: their dominance comes from placement and the first ball, not raw speed.

To compare two profiles before a specific match, the head-to-head comparator gives the surface-by-surface record player against player.

What it means for Wimbledon

On grass, the server starts with a bigger structural edge than anywhere else. Put simply, players who lean on their serve hold more easily, and a set can swing on a handful of points. That does not name a winner, but it explains why grass delivers tight scenarios, and why a single break is sometimes enough to settle a set.

Method

Data: WTA singles matches (main draws and tour-level events) since 2015 with complete serve statistics, close to 40,000 matches. Service-points-won percentages and ace rates are computed over the full set of service points for both players, surface by surface. The individual ranking keeps players active in 2024-2025 with at least 30 grass matches since 2015. Figures as of 10 June 2026.
