Abstract: By means of document materials , mathematical statistics and match observation , Djokovic's strategies to win has been studied in this paper .It puts 18 kinds of skill statistical data of 24 matches last-ing 6 race seasons during 2007-2012 into 2 groups to examine ,compare ,analyze .(12 matches who won in one group ,and another 12 who failed in another group) .From the data analysis ,we can found that the average of 12 kinds of skill statistical data that he won is better than that when he failed ,(including suc-cess rate of first serve ,ACE ,scoring rate of first serve ,scoring rate of second serve ,serve winner ,sco-ring rate of receive and serve ,break point ,the times of successful break point ,success rate of break point , scoring rate of fighting before net ,total score ,highest speed of tennis) ,the average of double faults and unforced errors is low ,but the average of 4 skill statistical data (times ,scoring ,and speed of first serve , and the speed of second serve) when he won less than he failed ;6 kinds of skill statistical data about sco-ring rate of first serve ,break point ,times of successful break point ,scoring rate of fighting before net ,to-tal score ,unforced error ,have significant difference between two groups (p<0 .05or p=0 .05) ,on score rate of receive and serve ,from the skill statistical data ,two groups have very great difference (p<0 .01) . Reference to all skill statistical data of the other 7 race seasons from 2006 to 2012 ,also integrating with his competitive performance ,we have this conclusion that these following reasons lead to his progress and vic-tory :the skill to be promoted ;more high scoring average of first serve and second serve ,the best player w ho has receive and serve skill ,more high success rate on break point ,the balanced ability of offensive and defensive ,abundant stamina and high fighting will .On the other hand ,Djokovic has his problem that whose skill of fighting near net is to be improved .This research gives a scientific reference for train and match of high-level tennis players .
