Eephus pitch

[2][3] The corresponding slow velocity bears more resemblance to a slow-pitch softball delivery than to a traditional baseball pitch.

"[11] Years later, however, Williams admitted that he had been running towards the pitcher's mound as he hit the ball, and photographs reveal that he was in fact a few feet in front of the batter's box when he made contact.

Bill "Spaceman" Lee threw an eephus referred to as the "Leephus", "spaceball" or "moon ball".

[14] The pitch resulted in a towering two-run home run over the Green Monster that Lee often said afterward "is still rising".

[16] Other pitchers known to have employed the eephus pitch include: Fernando Abad (the "super changeup"),[17] Al McBean (the McBean ball),[18][19] Luis Tiant, Pedro Borbón,[20] Yu Darvish,[21][22] Casey Fossum (called the "Fossum Flip"),[23] Steve Hamilton (the folly floater),[24] Liván Hernández, Phil Niekro,[25] Orlando Hernández, Dave LaRoche (LaLob), Carlos Zambrano, Vicente Padilla (dubbed the "soap bubble" by Vin Scully),[20][26] Satchel Paige,[27] Pascual Pérez (the Pascual Pitch), Kazuhito Tadano,[28] Bob Tewksbury,[29] Carlos Villanueva,[30] Alfredo Simón,[31] Clayton Kershaw,[32][a] Rich Hill,[33] Zack Greinke and unique wind-mill windup 1930s to 1950s pitcher Bobo Newsom.

[35][36] Other nicknames for the eephus pitch include the balloon ball, blooper ball, gondola, parachute, rainbow pitch—distinct from the rainbow curve[3]—gravity curve, The Monty Brewster (a reference to the titular character in Brewster's Millions), and the Bugs Bunny curve, a reference to the 1946 Bugs Bunny cartoon Baseball Bugs in which several batters in a row swing and miss at a very slow pitch before the ball reaches the plate.
