绕柱球（Around-the-Post，ATP）
Also known as: ATP
绕柱球，通常简称ATP，是一记绕过球网柱外侧、而不是越过球网打出的合法击球，可以在任何高度进行。它出现在一记角度锐利的球把球员拉到边线之外，让绕外侧成为回到对手场地的唯一路径时。
其合法依据在于规定球必须行进路线的规则：它必须落在对方场地内，但没有任何规定要求它在途中必须越过球网。一记绕过球柱外侧、完全越出场地边界、随后弯曲回来的球是完全合法的。它在经过时可以远低于球网高度，因为它根本没有越过球网。这正是它与一记正常抽击球或截击球（总是需要越网高度）的区别所在。
这个机会来自极宽的斜线轻吊球，或把球员拉过边线的锐利角度球。当一记角度锐利的球落在边线附近、并进一步向外弹跳或成角度时，追球的球员会到达场地边界之外。从那个位置，把球打回越过球网需要把它抬升到34到36英寸以上——但从那么宽的位置回到场地内的角度几乎不可能实现。绕到外侧解决了这个问题：在腰部或膝盖高度触球，弯曲回来让球刚好落在远侧边线内侧——通常是一记制胜球，因为对手已经站好位置准备防守常规回球。
这在技术上要求很高：要提前读球、坚定地投入追球越过边线而不是放弃这球，并施加由内向外的上旋或侧旋，把球弯回场内。到得太晚、还在奔跑中挥拍，很少能成功；最好的绕柱球是在追球结束后、从一个稳固的基础上打出的。为此拼一次，会让你的搭档独自覆盖整个场地，这正是为什么在高水平比赛中，提前喊出来是标准做法。
Chase every wide ball past the sideline before deciding whether to attempt it. Most players give up too early. Once you are genuinely outside, you can judge in real time whether height and balance permit the attempt or whether a safe reset over the net is wiser.
Engineer the chance with a crosscourt dink that angles your opponent wider than they expect. If your opponent is trying to bring you wide with their dink, read it early, start moving before the ball reaches the net, and arrive at the sideline in balance rather than at full sprint. A stable contact point is worth more than arriving a half-second earlier off-balance.
Example
一记锐利的斜线轻吊球被踢出边线之外；防守方追上去，在场地之外站定，在膝盖高度把球绕过球柱外侧弯回来——球落在边线附近，无法回击。
Why it matters
这一击把对手看似必胜的一球，转化为追球者的潜在制胜球。除了直接的价值之外，仅仅是这种威胁，就迫使对手对任何角度球都必须全力以赴，因为他们知道宽角球不会被轻易放弃。
How it shows up on video
Watch position relative to the sideline at contact. This means a legal attempt is struck from at or beyond the line, in the space beside or behind the post. The ball's trajectory after contact should curve noticeably back toward the court rather than traveling straight. Look for whether the player sets their feet before contact (higher success) or attempts the shot running full speed (lower success rate but sometimes necessary).
Common mistakes
- Not chasing wide enough — stopping inside the line makes the geometry impossible, since the shot requires being genuinely beyond the boundary.
- Making contact too late. This means swinging. At the same time, still running removes any controlled spin. The earlier the feet are set, the more reliably the ball bends back in.
- Applying no spin — a flat attempt leaves in a straight line and misses wide, because bending back into court needs deliberate sidespin or inside-out topspin.
- Not alerting your partner — the attempt leaves that whole side uncovered, and a call gives them time to shift.

SwingVantage identifies situations where the geometry allowed one. This means balls that pulled a player to or past the sideline. This means and shows whether it was attempted and whether contact and trajectory would have worked.
Frequently asked questions
球必须保持在球网高度以下吗？
不需要——完全没有高度限制。球只需要绕过球柱、落在对手场地内即可。实际上，大多数ATP都是在膝盖到腰部的高度打出的，因为当球员被拉宽时，球自然会到达这个高度，而且一记低球更难防守。
我可以跑出界外去处理这球吗？
可以——只要球在球员触球时尚未死球，球员就可以跑出场地边界（越过边线或底线）去处理它。离开场地去追一记宽球是合法的。
如果球在经过时擦到了球柱怎么办？
如果球接触到了球网柱，就算死球，击球方犯规。球必须绕过球柱，不能触碰它。
