Split-Finger Fastball

aka split-finger · splitfinger fastball

My split-finger fastball. I grip it almost like my two-seam, just spread the fingers a touch wider, outside the laces. It comes out at full fastball arm speed and drops late — a fastball that acts like a change, not a soft one.

Grip Evidence

The photo can say this much

This is the visual grip-reference layer for Split-finger fastball. It names visible placement and Austin's own feel notes, then stops before making measured claims.

Photo-supported grip cue

The tell is subtle: it can look close to a two-seam in Austin's hand, but the cue is the fingers spreading outside the lace tracks instead of sitting on them.

Pitcher's own words

Gripped almost exactly like the two-seam, except the fingers spread out wider — just outside the laces instead of right on them. With short, stubby fingers like mine you can barely see the difference. Those same short fingers are the reason I have never been able to throw a circle change.

I threw this some as a harder version of the changeup — it let me stay at full arm speed and feel more like a fastball than a traditional change at release, then drop. The fastball-tilt change, not a soft one.

What it really is

The split-finger fastball and the offspeed 'splitter' share a grip family; MLB pitch tracking files the split-finger under the offspeed splitter code, while this atlas files Austin's as a fastball — the way he gripped, threw, and classed it.

Reputable analysisWikipedia, Split-finger fastball

Sourced, not corrected: Austin throws this as a fastball (pitcher's own words). The offspeed 'splitter' label is MLB's tracking taxonomy, filed separately under the Splitter specimen. Both framings are kept; neither overrides the other.

Who throws itAustin H. — a situational pitch in his mix, the harder, fastball-tilt version of his changeup.

Study this first

Set the filed Splitter next to this and the difference is the intent: same finger spread, but Austin throws his at full fastball arm speed and files it as a fastball, where the league files the splitter as offspeed. Sourced, not corrected.
