Though Djokovic led 4-1, he could not keep hold of the break, and he was serving at 4-4, 30-30, when the match was stopped because of rain. That was just after 6pm, and only a few minutes later, CBS let it be known that they had decided to abandon the tennis for the day. It was 8pm when they resumed, and 20 minutes later the players were level at a set-all, after Nadal put a forehand into the net to lose his serve in the twelfth game. Nadal, having won the first 19 sets he had played at this US Open, dropped the twentieth. It seemed as though that rain delay had helped the Serbian.
