Every week, Tennis Analytics dives deep into the data, bringing you a stat of the week to help you understand tennis better and become a little smarter.
For the next few weeks, we will look at the WTA Top 4 – Barty, Halep, Osaka, and Kenin. What are the key match stats that separate them from the rest of the pack?
Findings are based on matches tagged by Tennis Analytics from 2018 to 2020.
Stat of the Week: 52%
The top WTA players win 52% of all points they play.
This is consistent with findings on the men’s side (see our September 23rd stat on the Big 3).
One percent makes a big difference in our sport, and has a “doubling effect”. For every 1% that you gain, your opponent loses 1%.
You can also see that Osaka and Kenin win points by hitting winners more often than Barty and Halep (not including aces & return winners).
Kenin is also slightly worse at the net than the other three players.
Point of the Week
What ranked player do you think wins 50% of total points?
At the time of writing this, Marketa Vondrousova who is ranked #20 in the world, won 50% of points she played from the past two years.
Where does it drop to 49%? Andrea Petkovic, ranked #100, won only 49% of points that she played.
1% is the difference between #20 and #100. Margins are small in tennis!
Our sport is not built for perfectionists. You will lose almost as many points as you win regardless of how good you are.
