DALLAS (AP) — Reilly Opelka faces potential discipline for his post-match comments about a chair umpire he called the “worst ump on tour,” the ATP said in a statement Friday.

Opelka criticized the umpire after he was penalized for twice swearing at a spectator, describing him as 'amateur hour' and 'bush league.'

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.
