Undaunted by last night's twin blasts in the city, which almost brought the curtain down on the tie, Ganguly lived up to the expectations and showed tremendous application even though his side still needs 89 runs to avoid follow-on after their rivals had scored 504 in their first essay.
Deep Dasgupta was batting with Ganguly at 22.
Ashish Nehra, also trying to make a comeback to the national team, did his bit to trouble Ganguly with couple of rising deliveries but Ganguly was soon in his elements, displaying his vintage form.
After the first drink, it was Ganguly versus North as the East were trying to avoid a follow on.
Resuming at 22/2 in reply to North's mammoth total of 504, the East depended heavily on their skipper and Ganguly seized the initiative and played a patient 239-ball knock, which included 11 fours and three huge sixes.
East suffered the first jolt when Nehra removed Abhishek Jhunjhunwala (32) and then allrounder Laxmi Ratan Shukla (15) fell to Rajesh Sharma. But Ganguly and Deep joined hands to stem the rot and put up an unbeaten stand of 68 runs.
Later talking to reporters, Ganguly said though he was disturbed by last night bomb blasts, he did not allow coming those things during playing.
The play began 45 minutes late because of extra security drill.
In fact three North Zone cricket players, including V R V Singh, had escaped unhurt after getting trapped in the Fancy bazaar, the scene of crime, last night.
North Zone 1st innings 504 all out Vs East Zone 1st innings 215 for 4 (S Ganguly not out 118, D Dasgupta not out 22)
