INSIGHTS: Shot Variety Explained

Corinne Dubreuil/ATP Tour

One of the newest INSIGHTS metrics, Shot Variety, provides an objective measure for how much a player mixes up their tactics and shot selection during match play.

Expressed as a percentage of all shots hit, Shot Variety is calculated by comparing the use of "core" shots — topspin groundstrokes hit through the opponent's baseline — with the use of variation. This variation can include deep or short slices, drop shots, topspin angles and shots at net.

The metric provides a useful tool to help demonstrate how a player's tactics compare to the rest of the ATP Tour. When viewed for a particular match, Shot Variety can also show how a player's shot selection compares to his own benchmarks from previous matches.

Out of players inside the Top 100 of the Pepperstone ATP Rankings, Daniel Evans and Alexander Bublik are the co-leaders in Shot Variety over the past 52 weeks, with both players hitting roughly 47 per cent of their shots with variation. For Evans, his 46.8 per cent score breaks down as follows: slices (25.1%), short slices (7.1%), drop shots (1.2%), angles (2.1%), net shots (11.3%).
