Runner on base. Pitcher starts delivery. Batter takes one step out of box, holds hand up and says time very loudly.
Pitcher stops delivery short, slows down arm, and sort of lets the ball drop out of his hand in front of his body.
Ump did not give time. Coaches and fans are yelling balk and ump initially agrees and runner moves over. Pitcher's coach comes out and talks, then the umps confer and send the runner back - no pitch.
Ruling was that the batter can't audibly deceive the pitcher into believing time was called with his voice.
The wild card that wasn't mentioned was that the pitcher sort of released the ball. So, could it had been called a ball, even though the pitcher abbreviated his montion and dropped the ball in front of his body - is that still considered a pitch?
