2016 MLB Umpire Manual: Rule Interpretations
47. CALLING TIME AFTER A BALK Rule 6.02(a) [former Rule 8.05]:
(8) If the balk is followed by a wild pitch, the Approved Ruling of Official Baseball Rule 6.02(a) [former Approved Ruling of OBR 8.05] provides that the runner may advance beyond the base to which the runner is entitled at his own risk. In that situation, the umpire shall call the balk in the usual manner but shall not call Time until all play has ceased (runners have stopped trying to advance and a fielder is in possession of the ball in the infield).
