With Wimbledon 2023 in full swing, let’s look at Math in Sports: Tennis. Tennis fans of the last decade are experiencing the game at a special time as all-time greats like Federer, Djokovic, and the Williams sisters (Serena and Venus) are dominating the game before our very eyes.

Statistics is a powerful tool for predicting wins and measuring greatness. Join Spark Math as we look at the numbers behind the greatest tennis players in the history of the game.

## Serena Williams by the Numbers

In celebration of the WTA agreeing to pay professional women tennis players the same as male players, let’s take a look at the statistics of one of the greatest women to ever pick up a racket: **Serena Williams**.

**$94,816,730** in prize winnings

**858-156** Career Wins to Losses

**367** Career Wins (All-Time Leader for Women)

**23** Grand Slam Singles titles (The record)

**14** Doubles Titles (With her sister, Venus)

**5** WTA Championships

**4** Olympic Gold Metals

### Sports Math Pop Quiz!

**What is Serena’s career win rate?**

*Hint: Her win rate can be calculated by dividing her total wins by the total number of games played.*

**How much prize money, on average, did Serena earn per win?**

*Hint: Look at her total earnings and her total wins.*

## Break Point Percentage

In crunch time, break points can turn the tide and win matches. A break point occurs when the returning player can win the game by winning the next point. Being the returning player is inherently more difficult in tennis, and the greats all excel at securing break points. To emphasize the difficulty of securing a break point, we will look at the break point percentage of three of the best men’s tennis players of all time:

Rafael Nadal has a 44.95% break point conversion rate, which is the 2nd highest ever.

Roger Federer’s and Novak Djokovic’s conversion rates are 44.10% and 44.27%, respectively.

That means that 3 of the best players lose over half of their break points!

### How do we calculate break point percentage?

To calculate the break point percentage, we first need to know how many points the player has converted and the total points. From there, we then divide the points converted by the total points.

Break Points Converted ÷ Total Points × 100% = Break Point Percentage

**Try to calculate Andy Murray’s break point percentage**.

Andy Murray’s Total Points = 8251

Andy Murray’s Break Points Converted = 3547

What is his break point percentage?

## Average Serve Speed

Average serve speed isn’t necessarily a predictor for wins and losses, but is a fun statistic to look at.

Fun fact: Sam Groth, a former professional tennis player from Australia, has the fastest recorded non-outlier serve in competition at 237 km/h. Let’s work on calculating the average serve speed of your child’s favourite tennis player.

To find the average serve speed, we need to know how to **Add** and** Divide**.

**Add**together the serve speed for all the instances you want to take an average of.**Divide**the sum above by the number of serves.

**Example:**

Serve 1: 170 km/h

Serve 2: 159 km/h

Serve 3: 175 km/h

Serve 4: 167 km/h

Serve 5: 169 km/h

Total speed across 5 serves: 170 + 159 + 175 + 167 + 169= 840 km/h

Average Serve Speed: 840 km/h ÷ 5 = 168 km/h
