球种排序
球种排序是指在整个打席中有意安排投球顺序——利用球种、速度、落点和变化，来铺垫并利用打者的反应。
没有任何一颗投球是孤立起作用的。一记上升球在一记变速球之后会变得更有效，因为打者此时正在为慢速球调整时机。一记内角下坠球会为一记外角曲球做铺垫。排序意味着每一颗投球都制造出一个问题，让下一颗投球来利用。顶级投手像下棋一样规划整个打席，用早期的投球做诱饵，用后期的投球设下陷阱。排序也要考虑球数：投手有利的球数（0-2、1-2）允许用一颗“浪费球”来为下一颗投球铺垫。
Start every at-bat with a defined plan of exactly three pitches. This means a setup, a change. A strikeout pitch. This means and execute the plan before adjusting to what the hitter shows.
Keep a running mental database of hitter reactions to each sequence pattern and update your plan based on in-game feedback rather than repeating a sequence a hitter has adjusted to.
Example
内角快速球，内角快速球（培养时机感），外角变速球（打乱它），随后是高角上升球（打者提前发力、从球下方挥棒，被判第三个好球出局）。

How it shows up on video
Chart pitch types and locations in order across multiple at-bats to reveal whether the pitcher is genuinely sequencing or defaulting to a go-to pattern after two pitches. Hitter swing quality will deteriorate if sequencing is working. This means early pitches produce squared contact. At the same time, later pitches in the sequence produce mishits that confirm the trap is set. A pitcher not sequencing will show consistent pitch type regardless of count or hitter reaction.
Common mistakes
- Repeating the same two-pitch pattern in every at-bat so opposing coaches chart and tip off hitters between innings
- Sequencing based on personal preference rather than the individual hitter's tendencies and weaknesses
- Over-complicating the sequence instead of executing each individual pitch to its location — sequence quality means nothing if location is poor
- Hitters not tracking pitch types across at-bats to identify the pitcher's sequencing habits before their next plate appearance

Motion Lab tracks your full pitch-type and location sequence across an at-bat timeline. This allows you to visualize the logic of each setup pitch relative to the pitches that follow it.
Frequently asked questions
一个打席应该提前规划几颗投球的顺序？
顶级投手会提前规划三颗投球，同时保持灵活性——如果打者在预期出棒的球数下选择放过，应立即触发排序调整。
如果投手球速快，球种排序还重要吗？
重要——即便在最高水平，单靠球速也无法产生足够的挥空；排序能倍增每一个球速和变化水平的效果。
