角落内野防守
Also known as: 一垒三垒防守, 触击防守角落
角落内野防守是指当短打战术在场时，一垒手和三垒手的防守分工与站位——冲上前防守触击球、读打者的推打动作，并在时间压力下执行正确的传球到正确的垒包。
在快投垒球中，当一名推打型或触击型打者站在本垒板时，一垒手和三垒手会面临独特的压力。他们必须提前读出打者的脚步动作和球棒位置，来判断该冲上前还是保持站位，随后迅速对球做出反应，在时间压力下完成守备和正确的传球。要正确防守面对一支擅长推打和触击的球队的角落，需要预判能力、赛前侦察，以及考虑跑垒员位置和比赛局势的清晰防守分工。
Know your assignment before the pitch. This means if you have been pre-assigned to throw to second on a bunt with a runner on first, make that decision before you field the ball, not after.
Film yourself from behind home plate against live bunt reps and measure the distance from home plate where you field the ball. This means elite corner defenders reliably field bunts within 20 feet. This provides time for force throws to all bases.
Example
一垒有跑垒员时，三垒手冲上前防守拖曳触击球，守备后传向二垒完成封杀——而不是选择在一垒轻松出局的容易选项。
How it shows up on video
Film from an elevated angle behind home plate to see corner positioning relative to home plate distance as the pitch is delivered. This means corners crashing too early tip their charge and can be beaten by a fake bunt into a swing. A well-executed corner play shows the first or third baseman breaking late enough to field the bunt but early enough to make a confident throw, not a rushed one. Watch for throw accuracy after fielding — most errors on corner plays happen in the throwing motion after a hurried field.
Common mistakes
- Crashing too early before reading whether the hitter is bunting or faking, allowing a pull-side ground ball to get past a vacated corner
- Fielding the bunt cleanly but hesitating on the throw decision, negating the aggressive charge with a tentative release
- Not having pre-assigned responsibilities for which base each corner defender throws to in each situation, creating confusion under pressure
- Playing back against known bunters because of fear of a swing, giving them unchallenged bunt singles down the line

Frequently asked questions
面对推打型打者，一垒手或三垒手应该每一球都冲上前吗？
不应该自动这样做——冲上前的时机应该由打者的早期脚步动作和球棒位置来触发，而不仅仅是投球出手，以避免被假动作骗过。
一垒有跑垒员时，角落触击球最安全的默认传球是什么？
传向领跑跑垒员——传向二垒完成封杀能消除最危险的跑垒员，只要这次传球能有信心地完成，就是正确的打法。
