Lorenzo Musetti's tennis is complete, and characterized by volleys, dropshots, accelerations, slices and topspins. the service ranges from flat solutions, in slices and in kicks reaching peaks of 200 km/h. In July 2022 he abandoned the foot-up technique to switch to foot-back. The second serve balls, with the foot-up, were often shy and the opponents could be aggressive right from the return.
He has one of the most complete one-handed backhands, which allows him to use it equally for effectiveness in both topspin and slices. He has good timing in anticipation of downfield shots, where the foot placement that gave him stability issues has been greatly improved, which allows him to timely counter-attack opponents' long balls. He also frequently uses the sliced backhand to slow down the opponent's game and change the momentum of the rally.
In playing the forehand, with an extreme western grip, he used an opening with the right elbow bent very far back and with ample preparations which prevented him from using the lead, above all in returning service on courts and therefore fast balls, where he was forced to back a lot from the baseline, and to choose a blocked return, with low percentages of points won on return, making him feel more comfortable on slower surfaces such as clay ones than on fast ones.
