Frances Tiafoe – American tennis hope – service remarks
With his 1st service, Frances could have quite a potential weapon at his disposal (after all his fastest service during the 2016 US.Open was clocked at 142 mph, same like the fastest service from John Isner), but small details are in my opinion often taking a bit away from its potential. The main issue is for me in the rather suboptimal integration of the body energy into the stroke in the moment of impact at most of Frances' services.
