Why Is Tennis So Far Behind Other Sports In Data Analytics?

Jim Pagels

Data analytics is coming to every sport in some capacity, though at varying speeds. Baseball has of course seen the sabermetric revolution of the last couple decades, and basketball, football, and hockey have all made great strides in the last few years.

Other sports have been more anemic, though, with one of the more glaring holes being tennis. The most comprehensive data out there, Hawkeye, which tracks the speed, trajectory, and spin rate of every shot, is not publicly available, and fans and reporters are usually subject to only the most trite and largely useless data such as break point percentage, aces, and winner totals.

At the 2015 MIT Sloan Sports Analytics Conference this past weekend in Boston, Tennis Abstract founder Jeff Sackmann presented work he’s done in tennis analytics—a field he seems to be alone in pioneering, at least in the public realm—and discussed some of the hurdles widespread tennis analytics face.

Tournaments: Tennis is a fragmented, decentralized landscape. Sure, there are the ATP and WTA with some degree of power over tournaments, but most events are very autonomous, and it’s difficult to align a uniform data tracking system when directors are most interested in maximizing their sponsorship deals with Rolex and Lexus. Many tournaments supply only physical paper stats PDFs to journalists, who then have to arduously transcribe the data back into their own computers for analysis.

Players: Individual sports are not as incentivized to gather analytics, as there’s no team-constructing component to the game. There’s no need to isolate individual contributions in tennis, since we can already tell just how much a player contributed to his or her success.

Sport: Given the lack of parity in men’s tennis, the public demand for analytics may not be too great, as even the most comprehensive data will be unlikely to turn the likes of John Isner or Gilles Simon into a regular title contender.

Sackmann says that he doesn’t expect to see anyone—players, coaches, or fans—paying for numbers any time soon, so for now, he is crowdsourcing match data. Sackmann has recruited an army of 30 volunteers meticulously tracking the shot type and location of every stroke for over 667 matches—a tiny drop in the bucket as Sackmann notes, but still a vast improvement over what was previously out there.

While that match tracking data is evolving, Sackmann says the best use of analytics right now is not so much in performance on the court but rather in selecting which courts to actually play on.

Which events to play is an easy decision for top players, but for players ranked outside the top 10, who often have to decide between multiple events of varying ranking points and prize money each week, these decisions can have huge monetary implications.

Players have to decide between bigger events with more prize money or ranking points, but also a tougher field that could knock them out early versus smaller events with fewer ranking points and prize money but an easier field they’d be more likely to progress further in. Sackmann says the decision is usually pretty basic, though: Players should almost select the bigger event, with the only exception being if a player is seeded in the smaller tournament but not the larger one.
