What The Heck Is An Eephus Pitch? What About The "Fossum Flip"? Are These Baseball's Next Big Pitches?

Fastball? Check! Changeup? Check! Breaking ball? Check! Eephus pitch? What?

The Eephus is one of baseball's rarest pitches. It's thrown overhand like most off-speed pitches, but is characterized by its unusually high arc of trajectory -- and its corresponding slow velocity -- bearing more resemblance to a slow-pitch softball delivery than to a traditional baseball delivery. 

It is considered a "trick" pitch because in comparison to normal baseball pitches (70 to 95 miles per hour), an Eephus pitch appears to move in slow motion. Hitters typically get anxious, swing wildly, or ground out.

Casey Fossum, above right, of the Tampa Bay Devil Rays now throws a form of the Eephus that is known to dip below 50 mph called the Fossum Flip. Think we'll be seeing more of it in baseball?
