※ 引述《LUVVY ( )》之銘言：
: 國際網總(ITF)的網球規則有一項和換球有關，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. 我看不懂這段
: 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. 這部份我看得懂，供參考用
: 有沒有人可以解釋一下呢？
: 謝謝！！
所以意思是說第8局會換新球，在接下來的話，會在第17局換新球嗎?
還有如果遇到tie-break，為何會是下一盤的第二局才換球啊?為何不是第一局?
實在有點看不懂耶!!
