Penyamaran Lemparan (Tunneling)

Also known as: tunneling

Definition

Pitch tunneling adalah prinsip melepaskan berbagai jenis pitch melalui "terowongan" visual yang sama di awal penerbangan sehingga terlihat identik hingga mereka menyimpang dekat plate, terlalu terlambat bagi pemukul untuk menyesuaikan.

Pemukul harus berkomitmen untuk swing sebelum bola mencapai titik tengah penerbangannya. Jika rise ball dan drop ball keduanya melewati zone yang sama tiga kaki di depan pitcher, pemukul tidak bisa membedakannya hingga setelah titik keputusan. Tunneling berarti mengoptimalkan titik release dan lintasan sehingga separuh pertama penerbangan identik; break-nya terjadi di zona mati pengambilan keputusan. Pitcher yang tunneling dengan baik bisa memiliki pitch yang secara statistik bergerak ke arah berlawanan tetapi terlihat sama saat keluar dari tangan.

Beginner tip

Focus first on keeping your release point identical for your two primary pitches. This means release point consistency is the foundation of tunneling before worrying about trajectory angles.

Advanced note

Pair a rise ball and changeup intentionally as a tunneling duo. This means same release, same initial trajectory, with the rise climbing high and the changeup dropping low after the decision point. This means making both pitches sharply more effective.

Example

Rise ball dan changeup pitcher keduanya terlihat setinggi lutut pada titik keputusan; pada saat mereka menyimpang — satu selesai di letters, satu di luar plate — pemukul sudah berkomitmen.

How it shows up on video

From a center-field camera angle you can see both pitches sharing the same visual cone for the first half of flight before they diverge near the decision point. This means if they look like the same pitch until 25 feet out, tunneling is working. Hitters will show identical swing initiation on both pitches, confirming they committed before seeing the break. Poor tunneling is visible as hitters reading and pulling off one pitch early while attacking the other confidently.

Common mistakes

Changing release point between pitch types, breaking the tunnel before the ball leaves the hand and giving the hitter early information
Pairing pitches that move in the same direction rather than opposite directions, reducing the exit-tunnel contrast that makes tunneling deceptive
Sacrificing location to maintain tunnel, producing pitches that break out of the zone rather than to a specific corner
Hitters not watching the release point carefully enough to notice when two pitches do not share the same early flight path, missing a pitch-tipping tell

Motion Lab maps the first-half flight path of multiple pitch types from the same release point, calculating how precisely pitches share the same visual tunnel before diverging.

Frequently asked questions

Apa itu "titik keputusan" dalam pitch tunneling?

Ini adalah lokasi kira-kira 20–25 kaki dari pitcher di mana pemukul harus berkomitmen untuk swing atau take — pitch yang terlihat identik hingga titik ini memaksa pemukul menebak.

Bisakah tunneling diukur secara objektif?

Ya — teknologi pelacakan mengukur tumpang tindih lintasan pitch pada separuh pertama penerbangan dan mengukur seberapa dekat pitch berbagi kerucut visual sebelum menyimpang.
