The use of statistics to understand results in professional tennis is in its infancy. One way of finding out more about what really happened in a match is to look at point-ending strokes. When doing so it’s important to remember that point-ending strokes include not only winners/forced errors, but they also include unforced errors.
What actually happened in Roger Federer’s stunning 5-set loss to Grigor Dimitrov? I make a convincing case that his injury was far worse than he led us to believe.
