According to The New Dickson Baseball Dictionary, the incurve was the “pitch now known as a screwball.”
A so-called incurve is nothing more than a ball thrown in a natural way with great force.
The language of the game changes substantially in every generation; a rising fastball becomes a four-seam fastball which becomes a four-seamer, a forkball becomes a split-fingered fastball which becomes a splitter, a drop curve becomes an overhand curve which becomes a 12-to-6 curve, an incurve becomes a fadeaway, a fadeaway becomes a screwball, and now almost nobody throws a screwball but people throw a circle change-up that does the same thing, sort of.
Or “incurve,” a term commonly used as the nineteenth century became the twentieth.
In a 1908 instructional book called How to Pitch, Bill Dineen says of the incurve/inshoot he used the terms interchangeably, “Speed is necessary for an inshoot … Do not become discouraged if you fail to see the ball positively change its course as it does in an outcurve … Practice will succeed in giving a sharp break to the ball, which may not amount to more than an inch or two …”
One might assume that the incurve is simply the reverse of the outcurve, which would be the reverse of the curveball … which is to say, a screwball.
