Uttar Pradesh shot Bengal out for 149 within the first two sessions at Eden Gardens and then their batsmen proceeded to knock off those runs in a hurry. Bengal, who opted to bat, had a 40-run opening stand before twin strikes from the Kumars - Bhuvneshvar, the debutant, and Praveen. The big wicket of Manoj Tiwary followed soon as Bengal found themselves down at 43 for 3. Wickets fell regularly after that and only a 39-run ninth-wicket stand between Saurasish Lahiri and Ranadeb Bose took them past 100. Praveen, Bhuvneshwar and Piyush Chawla took three wickets each. They didn't even require the services of Praveen Gupta, the specialist left-arm spinner.

Rohit Prakash and Tanmay Srivastava gave UP a brisk start, which was taken forward by Suresh Raina at the fall of Srivastava's wicket on 30. By the time Rohit fell for 58, just before stumps, UP were only 28 behind Bengal's total. Raina, who batted at a furious pace, was unbeaten on 55 off 67 deliveries.
