Squeezed out of the front of the hand with the thumb and first and second fingers, it keeps deceptively low after pitching and can accordingly be very difficult to play. The flipper is comparable to a riseball in fast-pitch softball. By putting backspin on the ball the Magnus effect results in air travelling over the top of the ball quickly and cleanly whilst air travelling under the ball is turbulent. The
Flipper (anatomy) Flipper (anatomy) A flipper is a typically flat forelimb evolved for movement through water. Various creatures have evolved flippers, for example penguins (also called "wings"), cetaceans (e.g. dolphins and whales), pinnipeds, and reptiles, such as some varieties of turtle and the now-extinct plesiosaurs, mosasaurs, ichthyosaurs, and metriorhynchids. Usage of the terms "fin" and "flipper" are often inconsistent, even in the scientific literature. The hydrodynamic control surfaces of a fish are always referred to a "fins" and never as "flippers", and limbs which have evolved into fin-like structures are usually (but not always) called "flippers" rather than fins, but the dorsal
