(Reuters) - Reilly Opelka has called for chair umpire Greg Allensworth to be suspended by the ATP after he received a code violation at the Dallas Open for confronting a spectator in the stands who he claimed was deliberately coughing to interrupt his serve.
Opelka, who was facing Cameron Norrie, was serving for the match in the last-16 when he stopped mid-serve at 30-30 to talk to a fan, asking him if he was coughing on purpose while also asking him to leave in an expletive-laden outburst.
