How AI and Analytics are Transforming Tennis

by Jon Scaccia December 11, 2024

What makes a tennis player great? Is it their lightning-quick reflexes, towering height, or pinpoint serves? While these traits certainly play a role, the answer may lie deeper—hidden in data. A recent study has analyzed the performances of 1,990 ATP players from the 2022 season, employing machine learning and statistical techniques to uncover what really separates the champions from the challengers. From serve speeds to age and even neural network predictions, this research not only demystifies the game but also points toward a data-driven future for tennis.

The Science Behind the Serve

Imagine this: a serve traveling at over 130 mph, landing just inside the service box’s edge. This precise combination of speed and accuracy can decide matches. In professional tennis, serves are pivotal—they set the tone for the game and often dictate its outcome. The study reveals that top-ranked players excel not just in serve speed but in “first serve points won” and “break points saved.” These metrics highlight their ability to maintain control under pressure, a skill that distinguishes the elite.

But the research also found that while serve metrics are crucial, they’re not everything. For example, return game performance—such as winning points off an opponent’s serve—plays an equally critical role, especially in prolonged rallies on slow surfaces like clay courts.

Age, Height, and Success: Are There Ideal Player Traits?

In tennis, age and height aren’t just numbers; they’re predictors of success. The study found that players ranked in the top 100 are generally older (average age: 26.8 years) and taller (average height: 187.7 cm) than their lower-ranked counterparts. Height provides an advantage in serves, giving players better angles and power, while age brings experience and strategic maturity.

However, being tall or older isn’t a guaranteed ticket to success. It’s about how players leverage these traits, combined with refined techniques and mental resilience. This finding underscores that talent, while important, must be complemented by relentless training and intelligent gameplay.

AI in Tennis: Game-Changer or Supporting Role?

Artificial intelligence (AI) is transforming tennis coaching, scouting, and analysis. The study introduced neural network models to predict ATP rankings, with one model achieving an impressive 96.8% accuracy. By analyzing variables like serve success, return metrics, and even tournament participation, these models can help coaches tailor strategies for players.

However, the researchers caution: AI is a tool, not a replacement for human expertise. While it can process millions of data points, it’s up to coaches and players to interpret and apply these insights effectively.

The Financial Divide: Winners and Others

The study also sheds light on the stark financial realities of professional tennis. While top players like Novak Djokovic earn millions in prize money, 87.7% of ATP players earn less than the average annual prize money of $105,442. For many lower-ranked players, covering travel and training expenses is a constant struggle. This financial gap underscores the importance of maximizing performance metrics to climb the rankings and achieve sustainability in the sport.

Implications for Coaches, Players, and Fans

This research offers practical takeaways for all tennis stakeholders:

• For Coaches: Focus on improving service and return metrics, particularly “first serve points won” and “total points won.” These are strong predictors of success.
• For Players: Leverage strengths like height and experience while addressing weaknesses. AI-driven tools can help fine-tune game strategies.
• For Fans: Understanding the data behind the game can deepen appreciation for the skill and strategy involved in every match.

The Bigger Picture: AI and the Future of Sports

The integration of AI in tennis is just the beginning. From scouting young talent to optimizing player performance, AI has the potential to revolutionize how sports are played, coached, and enjoyed. However, its greatest strength lies in collaboration—working alongside human intuition and experience to achieve the best outcomes.
