Mumbai 93 for 2 trail Rajasthan 155 (Solanki 77, Hazare 4-50) by 63 runs
Scorecard

A four-wicket burst from medium-pacer Swapnil Hazare confirmed Mumbai's dominance on the opening day against Rajasthan at the Wankhede Stadium. Rajasthan's decision to bat first backfired, with Vikaram Solanki ploughing through the wreckage with a stroke-filled 77. None of the other batsmen passed 12 as Hazare, Abhishek Nair (3 for 18) and Ajit Agarkar (2 for 60) inflicted the damage. Mumbai were a comfortable 93 for 2 at stumps, only 64 runs adrift of gaining first-innings honours.

Delhi were in early trouble after choosing to bat, slipping to 34 for 2, but a 67-run stand between Tehlan and Mithun Manhas revived them. Virat Kohli chipped in with 33 and Tehlan soldiered on all the way to stumps.

Hyderabad 258 for 6 (Yadav 79*, Teja 57) v Bengal
Scorecard

Ravi Teja kickstarted the game with a fiery half-century before Arjun Yadav consolidated Hyderabad's innings on the first day against Bengal at Uppal. Bengal's decision to field had disastrous results initially - Teja cracked nine fours in his 64-ball 57 and added 91 with his opening partner Tirumal Suman - but Ashok Dinda, the medium-pacer, struck four vital blows to help them fight back. Yadav resisted for 161 deliveries and carried the score to 258 for 6 at the end of the day.
