With Wimbledon 2023 in full swing, let’s look at Math in Sports: Tennis and Mathematics. Tennis fans of the last decade are experiencing the game at a particular time. All-time greats, like Roger Federer, Djokovic, Venus, and Serena Williams have been dominating the game in front of our eyes. Stats are a powerful tool for predicting wins and measuring greatness. Join Spark Math by Spark Education, as we look at the numbers behind the greatest tennis players in the game’s history.

## 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 stats of one of the greatest women to ever pick up a racket: Serena Williams.

## 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 3 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 and Novak Djokovic rates are 44.10% and 44.27% respectively. That means that 3 of the best players lost over half of their break points!

### How do we calculate break point percentage

We need to know how many points the player has converted and the total points. From there we will divide the points converted by the total points.

Break Points Converted/Total Points= Break Point Percentage

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

Andy Murray’s Total Points=8251

Andy Murray’s Break Points Won= 3547

What is his break point percentage?

## Average Serve Speed

Average serve speed isn’t necessarily a predictor for wins and losses, but it is a fun stat to look at. Fun fact: Sam Groth has the fastest recorded non-outlier serve in competition at 147 mph. Let’s work on calculating the average serve speed of your child’s favorite tennis player.

For finding an average we need to know** Addition** and** Division**

- Add together the serve speed for all the instances you want to take an average of
- Take the sum of that average and divide it by the number of serves.

**Example:**

Serve 1: 103

Serve 2: 99

Serve 3: 109

Serve 4: 102

Serve 5: 105

103+99+109+102+105=518

518/5=103.6mph
