Splitter or splitters may refer to:
A diffuser, in an automotive context, is a shaped section of the car underbody which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand (in area, density remains constant at the speeds that cars travel) so that it does not cause excessive flow separation and drag, by providing a degree of "wake infill" or more accurately, pressure recovery. The diffuser itself accelerates the flow in front of it, which helps generate downforce.
When a diffuser is used, the air flows into the underbody from the front of the car, accelerates and reduces pressure. There is a suction peak at the transition of the flat bottom and diffuser. The diffuser then eases this high velocity air back to normal velocity and also helps fill in the area behind the car making the whole underbody a more efficient downforce producing device by reducing drag on the car and increasing downforce. The diffuser also imparts upward momentum to the air which further increases downforce.
A split-finger fastball or splitter is a pitch in baseball derived from the forkball. It is named after the technique of putting the index and middle finger on different sides of the ball, or "splitting" them. When thrown hard, it appears to be a fastball to the batter, but suddenly "drops off the table" towards home plate—that is, it suddenly moves down, towards the batter's knees. Despite the use of the word fastball, it is used as an off-speed pitch.
The splitter grew out of a much older pitch known as the forkball which was used in the major leagues since the 1920s. The modern splitter is often credited to baseball coach Fred Martin who threw the pitch in the minor leagues as a changeup of sorts. When a young Bruce Sutter returned from surgery to find his fastball had lost velocity, Martin taught Sutter the pitch. Sutter's success as a closer helped popularize the pitch.
Another early proponent of the splitter was Roger Craig, a pitcher-turned-manager in the 1980s. He taught it to a number of pitchers on the teams he coached, the Detroit Tigers and San Francisco Giants. According to Mike Scioscia, the splitter was "the pitch of the '80s."
Through the gardens and fields 'neath the tall green grass
You were walking 'neath the moon while covering your tracks
Working your fingers down to the skin and stone
One hand on the hammer, one foot by the door
Pushed by the wind, fed by the need for moving on,
Moving on to nowhere
When division runs deep and down into the well
All the coins you dove after lost all their spell
Covered in moss walking for silver and blood
Out in the cafe, working in the grove
Guarding the port of the future you sold
Holding on, holding on to no one
Holding on, holding on to no one
One eye in the mirror, the other on the screen
Sewn in the pockets and down into the dream
Caught up in the mortar, bricks and heavy load
Wait in the shadows down the living road
Moving on, moving on to no one
