Laver Cup umpire explains why Medvedev wasn't disqualified as Tiafoe calls for action
Frances Tiafoe wasn't happy when Daniil Medvedev avoided a disqualification on the final day of the Laver Cup. The Russian faced Ben Shelton in the second match of the day and tempers flared when he gave his opponent a set point to take the first. Medvedev threw his racket and received a code violation for unsportsmanlike conduct.
