传球送球力
Also known as: 传球carry, 真直传球
送球力描述的是一次传球在飞行过程中保持球速和直线轨迹的能力，不出现横移、下坠或掉速——一次“送球力好”的传球会真实地飞抵目标。
一次送球力好的传球从出手到落地几乎保持相同的形状：不会在最后几英尺骤然下坠，不会向顺手侧横移，也不会在飞行中明显掉速。送球力取决于握法（干净的四缝线握法比握偏缝线传得更远更稳）、出手角度的一致性，以及随挥动作——以干净、减速自然的手臂路径出手的传球，通常比用蛮力或短臂发力的传球送球力更好。
送球力在长传中最为关键，因为微小的横移或下坠会随距离累积：一次从中外野或游击手深远位置传出、送球力好的传球，会沿着可预测的直线飞抵，让切球员或一垒手能够信任这条路线；而一次在后段突然下坠的传球，则会迫使对方仓促接球或临时调整。评估外野臂力或内野传球时，评估者会独立于原始球速之外密切关注送球力，因为一次又硬又飘或掉速的强传，往往不如一次速度稍慢但轨迹稳定的传球有用。
Example
他的臂力算不上顶级，但球从右外野一路真实地传向三垒，沿着一条平直、易接的路线飞抵目标。
Why it matters
送球力是与握法和出手一致性相关、可训练的品质，而不仅仅是臂力——球员可以在不单纯投得更用力的情况下提升它。
How it shows up on video
On video, good carry shows a throw holding a consistent, gently descending arc all the way to the target. Poor carry shows the ball dropping sharply in the final third of flight or visibly tailing off its initial line.
Common mistakes
- Assuming velocity alone determines throw quality, when a slower throw with better carry can be easier and safer for a teammate to receive
- Losing carry due to an uneven or rushed grip transfer rather than an arm-strength limitation
- Short-arming the throw under pressure, which reduces both velocity and carry at the same time
In SwingVantage Motion Lab
SwingVantage Motion Lab tracks release consistency and arm path across throwing reps. This correlates with how true a throw carries. This helps separate a carry problem from a pure arm-strength limitation.
Frequently asked questions
送球力和臂力是一回事吗？
不是——臂力指的是原始球速，而送球力描述的是传球在飞行中保持轨迹和速度的能力。臂力很强但送球力差的球员，传出的球仍可能出现难以预测的下坠或横移。
