I didn't pay attention to the broadcast last night (I was out celebrating Batman 75th anniversary) but it apparently was noticed in the broad cast by the "graphics guy":
"the only person who seemed to notice it was ball four was the graphics guy on Fox Sports Midwest. Matheny took blame for the miscue after the game."
