His groundstrokes are also quite powerful but tend to be mostly a bit less controlled and also less efficient than the groundstrokes of the very best players. In a general sense, Taylor's forehands and backhands have too much of an arm/forearm action while not...
Below, I am comparing Reilley's forehands at these two above mentioned events. I am surely aware that the coordination and an exact footwork are challenging at Reilly's size, but what I am focusing at is the way how he approaches the given strokes as this gives me certain information about the mental image of the stroke in his mind. In the case of an optimal "3 Step Tennis Stroke Regulation", the player puts the priority at the creation....
..back then, I was quite impressed by Jack's forehand, which he was unlike most other young Americans of his generation (Harrison, Young, Kudla, etc.) dominating rather by the body than by the arm action. He seemed to me like one who was able to stay immune to the widespread "infection" of the technique focusing at highest possible racket head speed and largely ignoring the importance of the body energy for the successful combination of power and stability/control in the strokes. It was, besides others, also Jack who brought me to the development of the model for the ideal body energy dominated modern forehand - Forehand 3.0...
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.
