The term "screwballer" is typically used in baseball to describe a pitcher who throws pitches that move in unusual ways, making it difficult for batters to hit. However, there are several other words that can be used to describe the same thing. These include "curveball pitcher," "knuckleball pitcher," and "spitball pitcher." The term "junkballer" is also sometimes used to describe a pitcher who relies on slower pitches and tricky deliveries rather than sheer speed. Regardless of the term used, screwballers are known for their unique style and ability to keep batters guessing, making them an important asset to any baseball team.
