The Serve

At Space City Tennis, we believe the serve is the cornerstone of competitive tennis—the one that starts every point, and the only stroke players fully control. 

We focus on establishing a technically sound, efficient serve built on proper body mechanics as a core foundation. 

Serving is about more than chasing raw power alone. Power without control produces inconsistent results. While brute strength can help beginners and early juniors, lasting success requires precision, consistency, and innovative technique.

Our expert coaches develop complete, high-efficiency serves grounded in proven kinetic-chain movements, biomechanics, and pinpoint accuracy.

The result? Reliable, tactical weapons that hold up under pressure and elevate performance at every level—from middle school matches to high school championships and beyond.

Probability of Winning Service (PWS)

At Space City Tennis, our proprietary Probability of Winning Serve (PWS) framework—honed over decades of studying the world’s best players—is the core metric that drives unbreakable service games.

PWS is far more than theory: it’s a precise, data-driven measure of how effectively any serve either wins the point outright or creates an unbeatable advantage on the next shot. 

Raising a player's PWS is the foundation of our entire system. A higher PWS means dramatically fewer break points faced and the ability to seize commanding leads in every set.

Master your serve. Control every point. Win more matches—starting with PWS.

To maximize each player’s PWS, our coaches refine every link in the kinetic chain:

• balanced footwork and stance
• deep knee bend and leg drive
• explosive hip and torso rotation
• continental grip variations tailored to spin and location
• toss placement and racquet-head acceleration at contact
• placement that systematically attacks returner weaknesses

At Space City Tennis, we don’t guess what works. We measure it, refine it, and turn serving into decisive advantages.

Recent PSW during the 2025 season:

• Novak Djokovic = 69% first serve percent; 118 average serve speed = 81.42
• Carlos Alcarez = 62% first serve percent; 120 average speed = 74.40
• Jannik Sinner = 54% first serve in; 122 average speed = 65.88
