How Novak Djokovic, the best returner, tackled Rafael Nadal’s new serve
世界上最好的回發球者－喬科維奇，如何處理納達爾的發球？
Playing a flawless game of tennis in the Australian Open final, Novak
Djokovic attacked Rafael Nadal’s backhand, made use of angles and the
elements. He smacked the ball into the stiff breeze blowing through the Rod
Laver Arena, and looped the ball with more spin when the wind was behind him.
Nadal, on the other hand, struck his trademark spinning forehands into the
wind and watched them fall short for Djokovic to whack. But the key to the
6-3, 6-2, 6-3 demolition job was how the returner supreme dealt with Nadal’s
improved serves, finds Gaurav Bhatt.
在澳網完全的比賽中，囧口攻擊納的反手，充分的利用了角度。當風從背後吹向他時，
他加了更多的旋轉（物理真好）。納達爾在逆風的時候，仍然打出他的招牌正手，
結果落點太短被囧口巴。當然比賽最重要的關鍵是囧口如何處理納的發球
After tinkering with his service motion during the injury layoff, Nadal
arrived at Melbourne holding the racquet down for longer and standing up
straighter. He twisted less and threw his body with a more headlong thrust.
As a result, his serves spun less and skidded through the court more, causing
a 5kmph increase in average speed. The low bounce meant the receiver hit back
with less control and Nadal could pounce onto a weak return. The follow
through was more aggressive too, as Nadal would step into the court, as
opposed to on clay where he steps behind the baseline after serving. At the
Australian Open, he served 6 aces per match, up from his career average of
2.9.
納達爾改進他的發球，轉速少，速度快，彈的低。他的發球平均快了5kmph, 低彈跳
讓回發者難以處理而回球弱。一旦回球弱，納就進入場內發動攻擊。在澳網，他
平均發出了6個Ace，比生涯平均多了一倍

A wide, power lifter-like stance, the precisely-timed short hop as the
opponent’s racquet makes contact with the ball, and analysing the server’s
cues account for Djokovic’s explosive movement. The Serb was already the
all-time best returner on hard court with a break point conversion of 45 per
cent and a return games win-rate of 32.4, i.e. a break in every three games.
He took those stats up a notch at the Australian open, converting 51 per cent
of break points and winning 39 per cent return games. His tally of 42 break
points earned was also the highest during the fortnight.
囧口在硬地上已經是史上最強的回發球者。他的破發率45%，回發球局勝率32.4%，
表示每三局他就可以破發一次。在澳網，他的破發點成功率來到51%，回發球局勝率
則是39%。在這兩星期中，他累積了高達42個破發點

Djokovic, who has dominated big servers like John Isner and Milos Raonic wasn
’t bothered by the 5kmph quicker Nadal serve. The wide serve directed at the
backhand of righties like Francis Tiafoe (39 backhand returns, 26 forehand
returns) and Stefanos Tsitsipas (33-21), earned Nadal free points.Nadal’s
success serving to the backhand in the quarter and semifinal was 86 and 80 %
respectively. Against Djokovic (36-30), it was 58 per cent.
專剋大砲型選手如Isner or Raonic的囧口，對於納達爾快5kmph的發球並沒有感到
困擾。納達爾之前導向對手反手外側的大角度發球幫他賺了很多免費的分數。在八
強和四強賽，納達爾發向反手邊的勝率高達86%和80%，對上囧口，只有58%
Nadal overcorrected as the match progressed, serving more often to Djokovic’
s forehand, allowing the Serb to cover the court more effectively. Also, 82 %
of Djokovic’s returns were deep (43% very deep) — as opposed to Tiafoe’s
72 and Tsitsipas’ 63. The deep returns, coupled with Nadal’s movement off
the serve, left the Spaniard with less time to react. He would step back to
respond, leaving himself open to sharp-angled shots
也因為如此，納達爾過度的反應，把球更多的發向囧口的正手，這讓囧口能夠更有效的
把球擊到球場上任何角落。另外，82%囧口的回擊球很深，43%的回擊球非常深。相對於
Tiafoe的72% 和Tsitsipas的63%，很深的擊球讓納達爾的反應時更短。這讓他的防守大
開，無法回擊大角度擊球。
