Lompatan Ancang (Crow Hop)

Definition

Crow hop adalah gerakan pitching ilegal di mana pitcher menanam kembali kaki pivot setelah push-off awal, secara efektif meluncurkan ulang dan mendapatkan keunggulan tidak adil dalam jarak atau momentum.

Fast-pitch yang legal membiarkan kaki pivot menyeret di tanah, dan aturan USA Softball (2022) dan NFHS saat ini juga mengizinkan leaping — kaki pivot melayang di udara — selama kaki tidak menanam kembali dan mendorong lagi; crow hop menanam kembali kaki, menciptakan titik peluncuran ekstra yang lebih dekat ke plate. Ini sering dipanggil ketika pitcher mencoba menghasilkan kecepatan tambahan dan dihukum sebagai illegal pitch. Memahaminya penting bagi pitcher yang belajar mekanik drag yang tepat — padanan legal dari menghasilkan drive sambil menjaga kaki tetap kontak.

Beginner tip

Practice dragging a chalk line with your pivot foot during dry mechanics drills. As a result, you can feel and see the legal contact path on every repetition.

Advanced note

Study slow-motion film of your own delivery in particular at the moment of push-off to confirm your foot maintains ground contact through the drag. This means small mechanics errors compound under game stress.

Example

Pitcher mengangkat dan menanam kembali kaki pivot-nya sebelum release; wasit memanggil illegal pitch, memberikan ball kepada pemukul.

How it shows up on video

From a side-angle video you will see the pivot foot lift clearly off the ground and land forward of its original position before the arm reaches the release point. This means a telltale second push rather than a continuous drag. The pitcher's hip will shift noticeably closer to the plate between the initial push and the second plant. Umpires watch for this by tracking the gap between the foot and the ground during the delivery.

Common mistakes

  • Lifting the heel rather than dragging it, creating a micro-hop that umpires still call as illegal
  • Confusing aggressive legal drive-and-drag with an illegal crow hop and becoming overly cautious, losing velocity
  • Not practicing the legal drag motion in particular, defaulting to a jump as the body seeks more momentum
  • Coaches missing the crow hop on slow-motion review because the foot barely leaves the ground

In SwingVantage Motion Lab

Motion Lab uses ground contact analysis on the pivot foot frame-by-frame to distinguish a legal drag from an illegal replant. This helps pitchers stay fast without the penalty.

Frequently asked questions

Apa hukuman untuk crow hop?

Ini dipanggil sebagai illegal pitch: menurut aturan saat ini sebuah ball diberikan kepada pemukul, dan kemajuan otomatis satu base runner tidak lagi berlaku dalam sebagian besar set aturan.

Bisakah pitcher tetap menghasilkan kecepatan tinggi dengan drag yang legal?

Ya — push-off legal yang kuat dengan drag yang berkelanjutan menghasilkan kecepatan yang sebanding dengan crow hop sambil tetap dalam aturan.
