Umpire's Warning?

[Georgiadore]

The home plate umpire gave a warning, fairly early in the game (I don't recall exactly when) to, I believe, Rocker. He also warned the dugout, according to the announcers, who didn't seem to know what it was about. Does anyone know?

There is a 20 sec clock that is used in tournament play and Kumar let it expire! Normally Kumar works quickly, this is a sign that he wasn’t right

Thank you!
