Alexander Zverev didn't disappoint as the headline act as the Ultimate Tennis Showdown 2 swung into action on Saturday, picking up a hard-fought victory over Felix Auger Aliassime. The German served up his fair share of entertaining plays at the exhibition event, pushed to a winner-takes-all sudden death breaker after a late surge by the Canadian. Grigor Dimitrov put in a more convincing display, concededing just one 10-minute quarter as he toppled Nicolas Mahut. And youngster Corentin Moutet managed to make a name for himself for all the wrong reasons in the all-French affair pitted against Benoit Paire, accusing the umpire of 'making a fool of himself', after Paire retired three quarters into their match.
