※ 引述《LUVVY ( )》之铭言：
: 国际网总(ITF)的网球规则有一项和换球有关，但是我看不太懂
: After an agreed number of games, in which case, the first ball change in the
: match shall take place two games earlier than for the rest of the match,
: to make allowance for the warm-up. 我看不懂这段
: A tie-break game counts as one game for the ball change.
: A ball change change shall not take place at the beginning of a tie-break
: game. In this case, the ball change shall be delayed until the beginning
: of the second game of the next set. 这部份我看得懂，供参考用
: 有没有人可以解释一下呢？
: 谢谢！！
所以意思是说第8局会换新球，在接下来的话，会在第17局换新球吗?
还有如果遇到tie-break，为何会是下一盘的第二局才换球啊?为何不是第一局?
实在有点看不懂耶!!
