封杀
Also known as: 封杀出局
封杀是指防守球员只需触碰跑垒员必须前进的那个垒包即可判定出局,不需要触杀,因为击跑员或后续跑垒员除了跑向那个垒包之外别无选择。
当击球员把球打进场内、且跑垒员身后没有空出的垒包时,跑垒员就被“迫进”了——例如,一垒有跑垒员时,一旦击球员成为跑者,该跑垒员就必须跑向二垒,因为一垒不能同时被两个人占据。在任何封杀局面下,防守方只需要一名持球的防守球员在跑垒员到达之前触碰垒包即可,不需要触杀跑垒员本人。一旦封杀局面中的领跑跑垒员被判出局,只要防守方能在其他被迫进的后续跑垒员到达各自垒包之前把球送到,这些跑垒员也会随之自动出局,这正是慢投垒球中常见的双杀和三杀封杀链条的成因。
正确理解封杀局面能避免浪费传球(去触杀一名本已在封杀中出局的跑垒员)和错失机会(在本应该是封杀局面时却传向错误的垒包)。
Example
一垒有跑垒员、一人出局,击球员打出滚地球给游击手,游击手触碰二垒即可完成对领跑跑垒员的封杀出局,不需要触碰任何人。
Why it matters
正确判读封杀局面,是把普通滚地球转化为出局、尤其是抓住双杀机会的基础。SwingVantage的规则词典能帮助休闲球员建立起在节奏更快的快投垒球或棒球阵容中常常被默认已经掌握的跑垒和防守常识。
How it shows up on video
On video, confirm which base situation existed before the pitch (which bases were occupied) to determine whether a given play was truly a force. This means the fielder touching the base and the ball's possession timing relative to the runner's arrival are the two things to check.
Common mistakes
- Tagging a forced runner unnecessarily instead of simply touching the base, wasting time that could complete a double play
- Throwing to the wrong base because the defense misjudged which runners were actually forced to advance
- Assuming a runner is forced when a base behind them is actually open, which means a tag is required instead
- Rushing a force-play throw so much that the fielder pulls off the base entirely, voiding the out
Frequently asked questions
什么情况下跑垒员算是被“迫进”?
当击球员变成跑者、而跑垒员身后没有空出的垒包可以退回时,该跑垒员就被迫进——例如,一垒有跑垒员时,只要球被打进场内,该跑垒员就永远被迫前进,因为击跑员正要占据一垒。
封杀局面中防守球员需要触杀跑垒员吗?
不需要——只要持球并在跑垒员到达之前触碰垒包,就足以完成封杀出局。
