The Serbian tennis player Novak Djokovic caught his second wind in the nick of time to overcome Davis Cup team mate Viktor Troicki in five sets in the first round of the US Open in New York.
Third seed Djokovic, who has struggled in the heat in the past, looked beaten after trailing 3-1 in the fourth set but the third seed came roaring back to avoid his first opening-round loss in a grand slam since the 2006 Australian Open.
The victory lifted Djokovic to a second-round match against Philipp Petzschner of Germany, who beat Dusan Lojda of the Czech Republic to advance.
