四缝线握法（传球）
Also known as: 传球四缝线握法, 正确握法转换
传球前横跨四条缝线握球——而不是球在手套里随意的落点——能产生笔直、真实且送球距离最大的传球，这是野手版本的投手四缝线快速球握法。
每一位守备球员都被教导，要在从手套到投球手的转换过程中找到四缝线握法，因为握偏缝线或只压着两条缝线的球，在飞行中往往会像出手不正的投球一样出现意外的横移、下坠或飘忽。野手没有投手那种从容寻找握法的余地；四缝线的手感必须在从手套到手的转换那一瞬间找到，这正是为什么在内野和外野的守备训练中，如此强调快速、正确转换的反复练习。
当速度比完美握法更重要时——徒手冲抢、鱼跃扑接、失去平衡的抛球——球员被训练成宁可接受不完美的握法，也要换取更快的出手，因为一次略带偏移但准确的快传，胜过一次握法完美却晚了半秒到达的传球。四缝线握法是默认追求的目标，而不是一条僵化的规则，优秀的内野手能立刻察觉握法不干净时的差异，并相应调整力量或轨迹。
Example
游击手的接传转换如此迅捷干净，以至于即便在中路的鱼跃扑接后，他也能找到真正的四缝线握法，传球一路笔直地飞向一垒。
Why it matters
一名在转换中稳定找到四缝线握法的球员，每一次传球——而不只是常规传球——都会有更好的送球距离和准度，这是防守中最可重复训练的基本功之一。
How it shows up on video
On video, a clean four-seam transfer shows the ball rotating minimally in the glove before the throwing hand settles across the seams. A rushed or off-seam grip often shows a visible extra adjustment or a throw that tails noticeably off its intended line.
Common mistakes
- Grabbing the ball however it lies in the glove without any grip adjustment, producing throws that tail or sink unpredictably
- Spending too long searching for a perfect grip on a play that requires a fast release, trading accuracy for lost time
- Failing to practice quick-transfer grip drills, so the four-seam feel never becomes automatic under game speed

Frequently asked questions
传球一定需要四缝线握法吗？
不一定——在速度至关重要的球中，不完美握法配合更快出手往往是更好的取舍。四缝线握法是追求准确的默认目标，而不是凌驾于比赛速度之上的规则。
