U.S. Open Player Spin (Page 14)

On the overhead, we recorded 4 incidents for the women averaging over 1200rpm, 3 of which were hit by Hingis. A single Michael Chang overhead on the men's side registered 1000rpm. In general we may conclude that although pro players generate substantial spin at the net, it is less than on the groundstrokes and on the serve. This conclusion makes obvious sense because of the far more abbreviated swing patterns at the net, as well as the lower velocity on the volleys compared to the other shots, as recorded in our ball speed experiments.
