Alexander Zverev won’t feature at this week’s China Open with the world No 2 revealing the reason behind his recent “physical difficulties”. Just weeks after losing against Taylor Fritz in the quarter-final of the US Open, Zverev suffered another defeat at the hands of the American in his opening singles rubber at the Laver Cup on Saturday. That loss came just a day after he and Carlos Alcaraz were beaten in the doubles by Fritz and Ben Shelton.
