Quick-Pitch Balk

A pitcher may not deliver a pitch before the batter is reasonably set in the box. Doing so is a balk.

Rule 6.02(a)(5) 2026 edition

If there is a runner, or runners, it is a balk when the pitcher makes an illegal pitch.

Rule 6.02(a)(5) Comment 2026 edition

A quick pitch is an illegal pitch. Umpires will judge a quick pitch as one delivered before the batter is reasonably set in the batter's box. With runners on base the penalty is a balk; with no runners on base, it is a ball. The quick pitch is dangerous and should not be permitted.

Rule 5.07(a) Comment 2026 edition

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.

Rule 5.07(a)(2) Comment 2026 edition

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 6.02(a)(5) Comment.
