# In my opinion after that epic encounter the 26-year-old Djokovic  undoubtedly confirmed his status of an ultimate 5-set warrior because at the time he had defeated in dramatic 5-set matches all the best players of the 10s (Federer even twice!). It didn’t seem it’d be the longest Wimbledon semifinal in the mid-2nd set when Djokovic led 3:2* (40/15) – Del Potro  played then his first volley, won it and the tables turned. In the 3rd set the Serbian saved break points at 2-all and 3-all, Del Potro came back from a triple set point down in the 12th game, but made an enormous error at the net trailing 2:3 to lose the tie-break 2/7. In the 4th set Djokovic led 4:3 (30/15) on serve, *6:4 in the tie-break when the Argentine survived a 25-stroke rally! Del Potro took the breaker 8/6, nonetheless from the beginning of the decider, Djokovic looked fresher. He saved a surprising break point at 2-all with a backhand winner down the line, and got the final three games, saving break point again in the last game (with his only dropshot winner of the contest). When I’m writing it now (Djokovic won today his Wimbledon ’18 quarterfinal vs Nishikori), it’s still the only time when the Serbian served 20 aces at least. I assume it might have been a day of his record in terms of volley winners as well (17).
