Change Up Meaning in Softball

Change up means a slower pitch designed to disrupt timing. The pitcher uses similar arm motion as a fast pitch. Reduced speed causes hitters to swing early. Grip and release create the speed difference. The pitch relies on deception rather than power. Consistent arm speed prevents hitters from recognizing it. Coaches teach mixing speeds to keep hitters uncertain. During an at-bat, the pitcher threw a change up after two fast pitches. The batter swung early and missed completely. Effective speed variation increases pitching success.
