Alexander Zverev on Saturday marked his return to competitive action for the first time since June following ankle surgery but said after his 6-4 6-2 loss to the Czech Republic’s Jiri Lehecka in the United Cup that he was some way from peak match fitness. Zverev, 25, had surgery to repair damaged ankle ligaments following an injury he sustained during his French Open semi-final against Rafa Nadal.
