Eephus pitch

An Eephus pitch (also spelled Ephus) in baseball is a very low speed junk pitch. The delivery from the pitcher has very low velocity and usually catches the hitter off-guard. Its invention is attributed to Rip Sewell of the Pittsburgh Pirates in the 1940s. According to manager Frankie Frisch, the pitch was named by outfielder Maurice Van Robays. When asked what it meant, Van Robays replied, "'Eephus ain't nothing, and that's a nothing pitch." Although the origin is not known for certain, Eephus may come from the Hebrew word אפס (pronounced "EFF-ess"), meaning "nothing". The Eephus pitch is thrown overhand like most pitches, but is characterized by an unusual, high arcing trajectory. The corresponding slow velocity bears more resemblance to a slow-pitch softball delivery than to a traditional baseball pitch. It is considered a trick pitch because, in comparison to normal baseball pitches – which run from 70 to 100 miles per hour – an Eephus pitch appears to move in slow motion at 55 miles per hour or less, sometimes into the low-40s.
