태그업
Also known as: 태깅, 리터칭, 희생플라이 진루
태그업이란 뜬공이 잡히는 순간 주자가 현재 베이스로 돌아가 터치한 뒤 다음 베이스로 출발하는 것을 말하며, 잡힌 뜬공에서 합법적으로 진루하는 방법이다.
뜬공이 뜨면 주자는 공이 잡힐 때까지 자신의 베이스에(터치한 채로) 머물러야 한다. 외야수가 공을 잡는 순간부터 진루할 수 있다. 뛰어난 태거는 발을 베이스에 붙인 채 외야수의 시선과 몸짓을 지켜보다가, 공이 글러브에 닿는 순간 폭발적으로 출발한다. 외야에서 나온 희생플라이 상황에서 3루 주자는 거의 항상 태그업해야 한다. 얕은 뜬공에서는 외야수의 위치, 주자의 스피드, 외야수의 어깨 세기가 모두 태그업으로 한 베이스를 더 얻을 수 있는지를 결정하는 요소가 된다.
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
그는 중견수 방향의 중간 깊이 뜬공에서 3루에서 태그업해 쉽게 득점했다 — 외야수의 위치를 읽은 그는 송구가 늦을 것이라고 판단했다.
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.
