Top Shots and Set Up Shots
In 2018, Kyle Edmund finished ranked No.14 in the world--the 14th best player on the planet. Yet, he lost 48% of all the points that he played. That's right, being able to win 52% of his total points was enough to rank him that high, amongst the tennis elite, and with the ability to gain huge earnings from prize money and sponsorship.
As you move down the rankings, winning 50% of total points in ATP Tour level events is good enough to comfortably maintain your position in the Top 100, while winning 55% will usually be enough to make you the No.1 player in the world. (Click Here for more detail on that from Craig O'Shannessy.)
These numbers are not only true on the tour. They translate to every level of the game all the way down to your local club singles league. Whatever level you play at, being able to win an extra 1% or 2% or 5% of the total points you play can make a huge difference in your results.
