Formula
Point Win % = Points Won on Serve / Total Service Points x 100
First serve win % = first serve points won / first serves in. Second serve win % = second serve points won / second serve points played. Total service win % combines both. Serve dominance ratio divides first by second serve win rate.
Worked Examples
Example 1: Strong Server Analysis
Problem:A player lands 65 first serves out of 100 total, wins 50 of those. On 35 second serve points, they win 18.
Solution:First Serve Win % = 50/65 = 76.9%\nSecond Serve Win % = 18/35 = 51.4%\nTotal Service Win % = (50+18)/100 = 68.0%\nFirst Serve % = 65/100 = 65.0%\nServe Dominance = 76.9/51.4 = 1.50\nPressure Drop = 76.9 - 51.4 = 25.5 pts
Result:Service Win: 68.0% (Excellent) | 1st: 76.9% | 2nd: 51.4% | Dominance: 1.50
Example 2: Weak Server Facing Return Specialist
Problem:A server lands 50 first serves out of 90 total, wins 32. On 40 second serve points, they win only 16.
Solution:First Serve Win % = 32/50 = 64.0%\nSecond Serve Win % = 16/40 = 40.0%\nTotal Service Win % = (32+16)/90 = 53.3%\nServe Dominance = 64.0/40.0 = 1.60\nPressure Drop = 64.0 - 40.0 = 24.0 pts
Result:Service Win: 53.3% (Average) | High second serve vulnerability at 40%
Frequently Asked Questions
What does point win percentage by serve mean in tennis?
Point win percentage by serve breaks down a player service game performance into two categories: first serve points won and second serve points won. The first serve win percentage measures how often a player wins the point when their first serve lands in the service box. The second serve win percentage measures success when the player must use their second, typically more conservative serve. Combined, these statistics give the total service point win percentage, which is the overall rate of winning points on serve. This breakdown is essential because it reveals the relative strength of each serve type and highlights whether a player needs to improve their first serve aggressiveness or second serve reliability.
What are typical first and second serve point win percentages on the ATP Tour?
On the ATP Tour, the average first serve point win percentage is approximately 72 to 74 percent, while the second serve point win percentage averages around 50 to 53 percent. The gap between these numbers, typically 20 to 24 percentage points, reflects the significant advantage of a strong first serve. The best servers on tour have historically achieved first serve win rates above 78 percent and second serve rates above 55 percent. Interestingly, second serve point win percentage is often more predictive of overall match success than first serve percentage because it measures ability to compete effectively even when the primary weapon is neutralized. Players with second serve win rates below 48 percent tend to struggle significantly.
How does the first serve percentage interact with point win rates?
First serve percentage and point win rates interact multiplicatively to determine overall service game effectiveness. A player with a 65 percent first serve rate and 75 percent first serve win rate gets 0.65 times 0.75 equals 48.75 percent of all service points won just from first serves. The remaining 35 percent of service points go to the second serve, where perhaps 50 percent are won, adding 0.35 times 0.50 equals 17.5 percent. The total becomes approximately 66 percent service points won. This interaction means that improving first serve percentage by 5 points can be nearly as valuable as improving first serve point win rate by the same amount, depending on the starting values and the overall balance.
What is serve dominance ratio and why is it important?
The serve dominance ratio is calculated by dividing the first serve point win percentage by the second serve point win percentage. A typical ATP player has a dominance ratio around 1.4, meaning they win about 40 percent more points on first serve compared to second serve. Higher ratios indicate a larger gap between first and second serve effectiveness, which can mean either an exceptionally powerful first serve or a weak second serve. Lower ratios suggest more consistent serve performance regardless of serve number. Players with ratios above 1.6 are highly first-serve dependent and become vulnerable when their first serve percentage drops. Players with ratios below 1.3 tend to be more resilient overall.
