Sentuh Base Ulang
Also known as: tagging, retouching, kemajuan sacrifice fly
Tagging up berarti baserunner kembali dan menyentuh base tempatnya berada saat fly ball tertangkap, lalu bergerak menuju base berikutnya — metode legal untuk maju saat fly ball tertangkap.
Ketika fly ball dipukul, baserunner harus menunggu di base mereka (menyentuhnya) hingga bola tertangkap. Begitu outfielder menyentuh bola, mereka boleh maju. Penag (tagger) elite mengawasi mata dan bahasa tubuh outfielder sambil tetap menjaga kaki di base, lalu meledak maju tepat saat bola menyentuh glove. Pada sacrifice fly dari outfield, runner di base ketiga hampir selalu harus tag up. Pada fly ball yang dangkal, kedalaman outfielder, kecepatan runner, dan kekuatan lengan outfielder semuanya menjadi faktor apakah tagging up menghasilkan tambahan base.
Position your foot on the inside corner of the bag. This means closest to the base you are advancing toward. This means before the pitch is delivered. As a result, when a fly ball is hit you are already in the optimal push-off position without needing to reposition.
Practice watching the ball into the outfielder's glove from a tagged-up position in particular by having a partner track fly balls in the outfield. At the same time, you stand with your foot on the bag and call "catch!" the instant you see glove-ball contact. This means this trains the precise timing discipline that separates tag-up masters from average baserunners.
Example
Ia tag up dari base ketiga pada fly ball sedang-dalam ke tengah dan mencetak angka dengan mudah — bacaannya terhadap posisi outfielder memberitahunya bahwa lemparan akan terlambat.
How it shows up on video
On video, tag-up quality is measured by the runner's foot position on the bag at the moment of catch, the direction the body is facing. The explosiveness of the first step off the bag. Common errors include the runner having both feet flat on the ground rather than positioned on the bag in a ready-to-push stance, the body facing the outfield rather than angled toward the next base. The runner losing contact with the bag for an instant before the catch. This means which creates a retouch obligation that negates the advance.
Common mistakes
- Leaving the bag too early before the ball is caught. This means even a tenth-of-a-second early departure is a legal violation that results in an out if appealed by the defense
- Standing flat against the center of the bag rather than on the inside corner with the body angled toward the next base, losing the push-off position advantage that fast taggers use to gain an extra step
- Making the tag-up decision based on the depth of the fly ball alone without considering the outfielder's arm strength, throwing angle. The presence or absence of a cut-off play
- Not watching the ball all the way into the outfielder's glove. This prevents precise timing of the departure. This means watching the fielder's glove make contact is the signal that must be seen before the departure step
In SwingVantage Motion Lab
SwingVantage measures foot position on the bag at the catch frame and timing of the first departure step relative to the catch contact frame, identifying early departures and measuring the body angle at departure. The system computes a tag-up efficiency score based on departure timing and initial step direction, benchmarked against the runner's historical best.
