How Equipment Enhanced Sam Stosur’s Game

See how Sam Stosur dramatically elevated her tennis performance through precise, data-driven equipment choices—and learn how you can do the same.

Key Points

  • Sam Stosur & Tennis Lab – Key Summary Points
  • The Collaboration: Sam Stosur partnered with Tennis Lab early in their research to explore ways to improve her game through better equipment choices—specifically racket, string, and tension.
  • Blinded Testing: Rackets were blacked out to eliminate brand bias. Testing was done on Tennis Lab’s Hawkeye Court to gather accurate performance data
  • Game-Changing Results:
    Sam had used the same racket for 10+ years.
    One test racket gave her 10% more ball speed and 5–8% more spin.
    She felt the difference immediately—and the data backed it up.
  • Why It Mattered:
    Her old racket was heavy with a small head size, making it harder to generate power.
  • Refining the Choice:
    One racket had too much spin, causing shorter rally shots.
    A second racket offered similar power with less spin and better depth, which became her final choice.
  • Long-Term Impact:
    She played the rest of her career with the new racket.
    Returned annually to Tennis Lab for minor tweaks to gain 1–2% extra performance.
  • Quote Worth Remembering:
    “How have I played the last 10 years with this racket and not explored anything beyond that?” – Sam Stosur
