Spectators who politely applauded Carballes Baena when he entered the stadium stood and roared for the 35-year-old Djokovic. A sing-song, soccer-style chant of “Olé, olé, olé, olé!” followed by the two-syllable moniker “Nole!” (pronounced NO-leh) echoed under the arena’s closed retractable roof, and would be repeated over and over: during the warmup period; when Djokovic switched sides of the net after the first game; when he was in the midst of climbing out of a love-40 hole in the first set (the only three break points he would face all night); when he broke to lead 4-3 in the second; etc., etc., etc. There were more of those cheers at the end, and Djokovic smiled broadly.
