Reason 1: The ball has a reduced backspin as compared to a regular fastball, and hence falls due to a stronger gravity than the upward Magnus force. This does not convince me. This scenario should result in a constant force on the ball throughout it's path of motion, and the descent should be gradual, and not be seen at the end of the pitch. Reason 2: The slight backspin on the ball forms ripple vortexes as it travels through the air, which eventually leads to the ball developing a topspin, which causes the ball to drop.
This reason seems to be more plausible, and can explain why the ball drops suddenly and not gradually. However, I'm not so convinced if this is a very accurate reasoning or not.
A pitch known as the knuckleball, thrown with very little spin, utilizes these vortices to make the ball move unpredictably. I'm not certain if the slight backspin allows the pitcher to control the effect these vortices have. It certainly does not have topspin at any point. The first reason is correct. It has less backspin and therefore appears to drop. The camera angle from behind the pitcher is deceiving. Although it appears to drop off suddenly, it is more gradual than it appears.
A straight fastball defies gravity quite a bit, as does a split fingered fastball, because they both have backspin. The splitter just does not defy gravity nearly as much. First off, there is no consistent answer to this question because there is no consistent pitcher, muscle power and slight variations in the manner in which the baseball is thrown will always produce different results from each throw. It seems to depend on the pitcher releasing the ball closer to the end of the arc of the swing on it than he normally would, he keeps his wrist loose and imparting a slight downward vector just before releasing it.

For those new to baseball, these pitch names may seem odd, compared with straightforward descriptions like fastballs and curveballs. Those balls are fast, or curve. Pitchers use many different grips to throw a changeup, and quite often these grips are quite personalized.
They learn to hold the ball however it feels best, or acts best, in the motion of throwing. This way is similar to a lot of changeup grips, where the ball is more snug with the palm, as opposed to pinching it between the index and middle fingers at top and thumb at bottom for fastballs.
It should form a little circle, maybe a half-inch wide. Place that circle on the side of the ball, and over the top let the middle and ring fingers go over the top, across or along a seam.
Pressure the ball with the middle and ring fingers at top, downward to the thumb; the pinky finger can lay limp, or some pitchers use it for additional stability or control.
A splitter grip is like a 2-seam grip, only the fingers are wider apart, often along the outside of those closest-together seams, instead of atop them. Fastballs are the most common type of pitch; basically anyone who picks up something and throws it forward with maximum effort is throwing a fastball. Nothing else was attempted to change the flight or velocity of the object in the air. This is what early baseball pitchers began tinkering with long ago: how to fool batters into thinking a fastball is coming, while in reality something slower will approach.
In the major leagues the change in miles per hour does not have to be severe, maybe 7 to 10 mph slower. The two pitches are gripped in almost the same way, except a splitter is generally held with more ease and placed toward the top of the fingers. Splitters are also thrown with the same minimal wrist action as a fastball, unlike the wrist-snap used for a forkball. The splitter received a great deal of recognition thanks to Hall of Fame reliever Bruce Sutter, who threw the pitch with regularity.
Splitter FS Definition A pitcher throws a splitter by gripping the ball with his two fingers "split" on opposite sides of the ball. Grip As mentioned above, a splitter is thrown with a pitcher's two fingers split apart by the baseball. Origin The splitter evolved from the forkball.
