外野防守深度
Also known as: 外野站位, 深守, 浅守
外野防守深度是指外野手与本垒板之间的距离。慢投联赛常常允许上场四名外野手;深度会根据击球员的力量、比分和出局数进行调整。
由于慢投击球员打出的高飞球比滚地球更多,外野站位往往比内野站位更具影响力。面对强力击球员时会要求深守;而擅长把平飞球打向各个方向的接触型击球员则可能要求浅守。在即将触发让分规则的局面下,外野手会整体加深,以防止长打。许多慢投联赛允许使用四名外野手,让两个空档各有一人防守,从而减少无法接住的高飞球数量。
Read the batter's stance and the inning before positioning. This means play shallower in early innings with no score pressure, deeper when protecting a lead late in the game.
In slow-pitch, most balls are hit in the air due to the high arc. Playing deeper than standard depth is often correct unless the batter frequently puts the ball on the ground.
Example
面对对方以打出高远长打著称的中心棒次击球员,外野比平时深守10英尺,把原本可能是两支本垒打的球变成了外野接杀出局。
How it shows up on video
Outfield depth positioning is visible from overhead or side-angle video as outfielders playing shallow (near the infield grass edge), standard depth, or deep (near the fence). Playing in trades line-drive singles for preventing base hits from dropping in front; playing deep prevents extra-base hits but allows shorter fly balls to fall.
Common mistakes
- Playing the outfield at the same depth for every batter without considering the arc's effect on ball carry distance
- Failing to shade left or right based on the batter's pull tendency, allowing routine fly balls to become extra-base hits
- Not communicating outfield alignment with infield positioning — gaps need to be covered by the correct combination of depths
- Standing flat-footed at depth rather than staying on the balls of the feet in a ready stance
