Pressure is one of those concepts in tennis that we all know exists but we struggle to calculate. I’ve made multiple attempts at quantifying scoreboard pressure and have yet to come around to one that is both statistically useful and easy to interpret. But some recent experimenting has uncovered what I think could be as close to a ‘best’ statistic for pressure as I am likely to find.
After introducing Pressure Ratings for matches, this post looks at how a similar approach can be used to develop a Set Competitiveness rating for players.

Do the numbers on the scoreboard affect how a player performs? In this post, we look at how to measure scoreboard effects and identify some top players who appear vulnerable and others who seem impervious to the scoreboard.
