Somdev began the match with a bang breaking Istomin in the very first game and then going to hold his own serve for a quick 2-0 lead. He continued with the momentum early in the 3rd game when he won 2 break points but the big serving Uzbek kept himself in the hunt with some long rallies going his way. But, after an unending game that lasted no less than 15 minutes, Somdev came up with a baseline stunner to clinch advantage and Istomin double faulted immediately afterwards to give Indian the game.
With 2 early breaks, Somdev was never really going to lose momentum and that is what happened in the remainder of the first set as he broke Istomin for the 3rd game in a row and although Istomin engineered a mini comeback breaking Somdev for the first time in the 6th game of the set, it was a case of too little too late for the Uzbek as Somdev broke back again to wrap up the first set 6-1
