Eight kilometres per hour. That is the average increase on Iga Swiatek's first serve this hard-court season — and it has turned her most attackable shot into a genuine weapon.
What changed
Slow-motion analysis shows a higher ball toss and a more aggressive leg drive, letting her hit up and through the ball rather than guiding it. The contact point is roughly 12 centimetres higher than last season — a small change with massive consequences.
Why it matters
First-serve points won are up from 64% to 71%. On hard courts, where the returner has less time, that seven-point swing is the difference between tight three-setters and routine straight-set wins. Her hold percentage now leads the tour.
“She didn't rebuild the serve. She just removed the caution from it. The mechanics were always there.”

The takeaway for club players
Toss it higher, trust the legs, and swing freely. Swiatek's upgrade is a reminder that the serve is the only shot you fully control — and small technical courage pays off fast.
