Delhi captain Gautam Gambhir used six bowlers, with only two proving to be successful.
Gujarat were off to a bad start losing three wickets with just 67 runs on the board. After the well-set Juneja was dismissed by Nehra to make it 124/4, Venugopal Rao and Merai joined hands to forge a century stand and stabilised the innings. Their partnership was broken when Narwal bowled Merai in the day's 73rd over.
