Power. Precision. Wit.

We break down why Serena Williams is such a dominant force in tennis.

THE ROAD TO NO. 1

One of Williams' most impressive accomplishments is the longevity of her time at the top. At 35, Williams is older than the average age of the current top 10 player by eight years. The only other female pro her age or older in the top 50 is her sister Venus Williams, 36.

Williams has won more singles, doubles and mixed doubles titles combined than any other pro – male or female. Her 2017 Australian Open victory secured one of the highest all-time tennis records: most Grand Slam titles in the Open Era.

What is a Grand Slam?

Professionals play different tournaments year-round but the most important are the four Grand Slam tournaments: The Australian Open, French Open, Wimbledon and U.S. Open.

"SERVICE, WILLIAMS"

These are two words you should dread hearing from an umpire when facing Williams on the court, due to the speed and power of her serve.

"Serve is very important for me, I think in general. I feel really dominant when I do serve like that."
–Serena Williams

Williams' 128.6 mph serve

What’s equally as important, but sometimes glossed over is a second component of Williams' serve: her deadly accuracy.

The last component is her ability to disguise her serves, making it hard for the opponent to anticipate where the ball will go. This combination is why her serves are such a dominant part of her game.

First serve placement
7.8% 45.8% 46.4% Center Wide Body

Williams usually hits down the “T” (center) or wide on her first serves, according to an analysis of roughly 3,500 serves. Hitting out in either corner, while risky, makes it harder for the opponent to return the ball.

Second serve placement
42% 25.2% 32.5% Center Wide Body

If she does not make her first serve, Williams usually hits toward the opponent’s body, based on an analysis of 2,400 second serves.

The combination is also why Williams' ability to ace an opponent is unmatched in women’s tennis.

What is an ace?

Every point starts with one player serving. An ace occurs when the receiver is unable to touch a legal serve with her raquet, usually due to speed or angle.

The queen of aces

Out of any female tennis pro, Williams is by far the most likely to serve an ace by a margin of 3 to 1.

When compared to the men, Williams' likelihood to serve an ace is still twice the average.

When she's down a point, the margin can become even greater, according to analysis done by IBM. In the video below, Williams is down a game at the 2012 Wimbledon finals and serves four aces in a row to break even (she eventually won the match, and set the record for most aces served by men or women at the tournament that year):

Could you return Williams' serve?

In the real world, probably not. But in our simulation, maybe. See if you are able to just get the timing of trying to return her serves in the stripped-down environment below.

PLAYING THE POINT

As a strong baseline player (playing at the back of the court versus at the net), Williams' forehand and backhand are one of the best in womens tennis. The dominant shot method, used in the charts below, was developed by Nikita Taparia, an engineer and scientist at the University of Washington (read the full methodolody here).

ABOUT THE DATA

Ranking data come from the Womens Tennis Assn. and ATP. Match data was available by the Tennis Abstract Match Charting Project by Jeff Sackmann which is the largest tennis open-source dataset available. Though detailed records of more than 1,400 professional matches comprise the dataset, not all matches are recorded for individual players.
