Pagtatago ng Pitch

Also known as: tunneling

Definition

Ang pitch tunneling ay ang prinsipyo ng pag-release ng maraming uri ng pitch patawid sa parehong visual na "tunnel" sa unang bahagi ng flight kaya't magkatulad ang hitsura nila hanggang sa maghiwalay sila malapit sa plate, sobrang huli na para mag-adjust ang hitter.

Dapat mag-commit ang hitter sa pag-swing bago umabot ang bola sa kalahati ng flight nito. Kung dumaan ang rise ball at drop ball sa parehong zone tatlong talampakan sa harap ng pitcher, hindi mahihiwalay ng hitter ang mga ito hanggang pagkatapos ng decision point. Ang ibig sabihin ng tunneling ay ang pag-optimize ng release point at trajectory para identical ang unang kalahati ng flight; nangyayari ang break sa decision-making dead zone. Ang mga pitcher na magaling mag-tunnel ay maaaring may mga pitch na statistically gumagalaw sa kabaligtaran na direksyon pero magkatulad ang hitsura mula sa kamay.

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

Parehong mukhang knee-high sa decision point ang rise ball at changeup ng pitcher; sa oras na maghiwalay sila — isa natatapos sa letters, isa lampas sa plate — nakacommit na ang hitter.

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

Ano ang "decision point" sa pitch tunneling?

Ito ang lokasyong humigit-kumulang 20-25 talampakan mula sa pitcher kung saan dapat mag-commit ang hitter sa pag-swing o pagkuha — ang mga pitch na magkatulad ang hitsura hanggang sa puntong ito ay pumipilit sa hitter na manghula.

Masusukat ba nang objectively ang tunneling?

Oo — sinusukat ng tracking technology ang overlap ng mga trajectory ng pitch sa unang kalahati ng flight at quinantify kung gaano kalapit magbahagi ang mga pitch ng visual cone bago maghiwalay.
