However, the severe heat took a toll on Mullings, who started suffering cramps, which played a part in preventing a huge upset in the men's singles.
Mullings took a medical time out in the seventh game of the first set and that changed the tide turned in the favour of Somdev.

India captain Rajpal Singh said his team will try to conceded less mistakes against the Australians on Thursday.
"I am happy. Since we played World Cup here, there was no pressure. The crowd support has helped us a lot. We will try not to repeat the mistakes we committed against Australia in the World Cup," he said.
