Sinner Tracked by GPS (But Doesn't Love It)

After winning the first set against Dutchman Jasper de Jong, Sinner took off his shirt to get rid of the black top that contained the GPS positioned on his back, a device that he wore in Rome both in training and in the first match with Mariano Navone. It is a machine authorized by the ITF (International Tennis Federation) since 2019 and that the Italian tennis player had already tried that year in training. Now it can be used in official matches and is useful for the data it provides, especially in the case of Jannik who returned to play after three months of absence from the courts, with the pressure, physical effort, sprints and stretches of a tournament match. The heart rate monitoring and the detection of positions on the court, kilometers traveled, average and maximum speed, accelerations are in real time: the device transmits the data to a connected tablet.

Six years ago, when Sinner was at the Piatti center, Riccardo Piatti declared, quoted by Supertennis, on the eve of the Next Gen that Jannik would not use him «in the match because at the moment he finds him uncomfortable, he feels him moving when he moves and he is not at ease. He is very sorry because (...) biometric data during the performance can be very useful in the growth of a player».

Today we will see, the appointment is at 3 pm with the Argentine Francisco Cerundolo for the eighth finals. A tricky match, the direct clashes are tied: 2-2. They have not faced each other since 2023, when Jannik was defeated in Rome. But since then it seems like a geological era has passed.
