A "straight ball" is a type of pitch in baseball that travels directly toward the batter without any significant movement. It is typically thrown with a consistent speed and trajectory, making it easier for the batter to predict and hit. The straight ball is often used by pitchers to establish control and set up other pitches. In baseball, the straight ball is commonly referred to as a fastball. It is one of the most fundamental pitches in a pitcher's arsenal. While it may seem simple, mastering the straight ball is crucial for pitchers, as it lays the foundation for more complex pitches like the curveball or slider.
