Double faults are a necessary evil of our game.
雙誤在比賽中是絕對無益的
Missing a second serve tends to sting a lot more than missing a forehand or a
backhand, especially if the double fault occurs at an influential moment
during a match. Double faulting on break point represents the worst timing,
but it still happens even at the elite level of our sport.
一個二發失誤比正拍或反拍失誤還要致命，特別是在一場比賽的關鍵時刻。
如果在破發點出現雙誤，那真的是最糟糕的時機，但它卻在頂尖的賽場上持續發生著。
An Infosys ATP Beyond The Numbers analysis of double faults, and their timing
in a match, illuminates an incredible strength of former World No. 1 Roger
Federer -– the ability to get his second serve in the box under pressure.
ATP分析了比賽當中雙誤的數據，發現前世界第一 Roger Federer有著不可置信的實力 -
在壓力下把二發發進的能力。
From the beginning of the 2015 season up to Roland Garros this year, Federer
was committing a double fault on break point only once every 22 matches. That
is head and shoulders above his peers in the Elite Eight, and speaks equally
to his fluent, graceful motion as well as the mental fortitude required to
get the ball in play with the match on the line.
從2015季初一直到今年法網前，Federer平均每22場比賽才會出現一次破發點的雙誤。
這在世界前八當中是一個非常優秀的數字，用優雅流暢以及毅力來完成比賽。
選手 平均發生破發點雙誤的場數

Djokovic 11.4
Nishikori 7.4
Wawrinka 6.5
Nadal 5.5
Murray 5.2
