是的，所以那天Federer有抗议Nadal故意拖延，看以下规则。Tennis is a gentlemen's/lady's

这些规则应该被遵守，这次对犯规的网开一面了。今早Stan抗议是应该的。

Continuity of play

As per the Rules of Tennis, play must be continuous. Players are allowed up to 20 seconds between points, however the receiver must play to the reasonable pace of the server. At the change of ends there is a 90-second break except after the first game of each set (players must change ends without a break). At the completion of each set, there is a two-minute rest period.
