冲抢滚地球
Also known as: 冲向来球, 抢攻慢滚地球
冲抢滚地球是指主动跑向一颗打得很慢的球，而不是等它自己滚过来——从而缩短传球距离，在触身球或慢滚地球变成安打之前先一步解决它。
面对一颗击打有力的滚地球，内野手的任务大体上是做出反应、挡在球前；而面对一颗打得很慢的球或触身球，如果等球自己滚过来，就会给打者兼跑垒员太多时间安全上垒。冲抢则是主动出击迎向来球，迅速缩短距离，这样传向一垒的距离更短，野手也能从一个更低、更具运动感的姿势出手，而不是原地站定弯腰去接球。
这项技术要求几乎在球离棒的瞬间就判断出球速和轨迹——如果冲上去的球实际上打得比预期更用力，野手可能因此站位失当，或是在全速前冲的同时接一个不规则弹跳的球。由于冲抢球的容错空间如此之小，接球和传球动作往往被合并成一个连续动作（徒手拾球并出手，或快速的手套铲球加转换），而不是野手先完全停下再传球。
Example
三垒手立刻读出这是一次触身球，全力冲上前去，在移动中徒手接球，跨身传出，以一步之差在一垒杀出出局数。
Why it matters
果断冲抢（或正确地判断不冲抢）是最容易在录像上训练的判断之一，因为面对慢滚地球时的犹豫，通常表现为起步延迟，而不是缺乏原始速度。
How it shows up on video
On video, a well-charged ball shows the fielder's first step coming almost immediately off contact. This moves in a direct line to the ball rather than drifting. A poorly read charge shows a fielder standing upright and reacting late, then being forced into an off-balance, rushed pickup.
Common mistakes
- Hesitating before deciding to charge, turning a routine bunt or slow roller into a close play or a hit
- Charging too aggressively on a ball that turns out to be hit harder than expected, resulting in a bad hop taken at full speed
- Failing to lower the body and get the glove down early enough while still moving forward, leading to the ball skipping under the glove

Frequently asked questions
什么时候内野手不应该冲抢慢滚地球？
当球被打得足够用力、球速真的存疑时，或者冲抢会让野手在更可能发生的次要防守中处于不利位置时——无论朝哪个方向判断错误，都会带来实际代价。
