“I never called a balk in my life. I didn’t understand the rule.” – Ron Luciano

Yeah, so, we saw three balk calls in a single game last night so I figured it might be nice to identify the balk rule for anyone who doesn't know it. If you already know what it is then skip to my previous post that has a great video of the George Brett Pine Tar Game.

Straight from the rule book:

Rule 2.00 – Definitions (page 17) A BALK is an illegal act by the pitcher with a runner or runners on base, entitling all runners to advance one base.

Rule 2.00 – Definitions (page 22) An ILLEGAL PITCH is (1) a pitch delivered to the batter when the pitcher does not have his pivot foot in contact with the pitcher’s plate; (2) a quick return pitch. An illegal pitch when runners are on base is a balk.

Legality of pitches, you ask?

8.00—The Pitcher. 8.01 Legal pitching delivery. There are two legal pitching positions, the Windup Position and the Set Position, and either position may be used at any time.

Pitchers shall take signs from the catcher while in contact with the pitcher’s plate. Rule

8.01 Comment: Pitchers may disengage the rubber after taking their signs but may not step quickly onto the rubber and pitch. This may be judged a quick pitch by the umpire. When the pitcher disengages the rubber, he must drop his hands to his sides. Pitchers will not be allowed to disengage the rubber after taking each sign.

The Windup Position. The pitcher shall stand facing the batter, his pivot foot in contact with the pitcher’s plate and the other foot free. From this position any natural movement associated with his delivery of the ball to the batter commits him to the pitch without interruption or alteration. He shall not raise either foot from the ground, except that in his actual delivery of the ball to the batter, he may take one step backward, and one step forward with his free foot.

When a pitcher holds the ball with both hands in front of his body, with his pivot foot in contact with the pitcher’s plate and his other foot free, he will be considered in the Windup Position. Rule 8.01(a) Comment: In the Windup Position, a pitcher is permitted to have his “free” foot on the rubber, in front of the rubber, behind the rubber or off the side of the rubber.

From the Windup Position, the pitcher may: (1) deliver the ball to the batter, or (2) step and throw to a base in an attempt to pick-off a runner, or (3) disengage the rubber (if he does he must drop his hand to his sides). In disengaging the rubber the pitcher must step off with his pivot foot and not his free foot first. He may not go into a set or stretch position—if he does it is a balk.

Glad we cleared that up. So --

b) The Set Position. Set Position shall be indicated by the pitcher when he stands facing the batter with his pivot foot in contact with, and his other foot in front of, the pitcher’s plate, holding the ball in both hands in front of his body and coming to a complete stop. From such Set Position he may deliver the ball to the batter, throw to a base or step backward off the pitcher’s plate with his pivot foot. Before assuming Set Position, the pitcher may elect to make any natural preliminary motion such as that known as “the stretch.” But if he so elects, he shall come to Set Position before delivering the ball to the batter. After assuming Set Position, any natural motion associated with his delivery of the ball to the batter commits him to the pitch without alteration or interruption.

Preparatory to coming to a set position, the pitcher shall have one hand on his side; from this position he shall go to his set position as defined in Rule 8.01(b) without interruption and in one continuous motion.

The pitcher, following his stretch, must (a) hold the ball in both hands in front of his body and (b) come to a complete stop. This must be enforced. Umpires should watch this closely. Pitchers are constantly attempting to “beat the rule” in their efforts to hold runners on bases and in cases where the pitcher fails to make a complete “stop” called for in the rules, the umpire should immediately call a “Balk.”

Rule 8.01(b) Comment: With no runners on base, the pitcher is not required to come to a complete stop when using the Set Position. If, however, in the umpire’s judgment, a pitcher delivers the ball in a deliberate effort to catch the batter off guard, this delivery shall be deemed a quick pitch, for which the penalty is a ball. See Rule 8.05(e) Comment.

(c) At any time during the pitcher’s preliminary movements and until his natural pitching motion commits him to the pitch, he may throw to any base provided he steps directly toward such base before making the throw. Rule 8.01(c) Comment: The pitcher shall step “ahead of the throw.” A snap throw followed by the step directly toward the base is a balk.

(d) If the pitcher makes an illegal pitch with the bases unoccupied, it shall be called a ball unless the batter reaches first base on a hit, an error, a base on balls, a hit batter or otherwise. Rule 8.01(d) Comment: A ball which slips out of a pitcher’s hand and crosses the foul line shall be called a ball; otherwise it will be called no pitch. This would be a balk with men on base. (e) If the pitcher removes his pivot foot from contact with the pitcher’s plate by stepping backward with that foot, he thereby becomes an infielder and if he makes a wild throw from that position, it shall be considered the same as a wild throw by any other infielder. Rule 8.01(e) Comment: The pitcher, while off the rubber, may throw to any base. If he makes a wild throw, such throw is the throw of an infielder and what follows is governed by the rules covering a ball thrown by a fielder.

You're welcome.
