Shankar and Sundar fought well on either side of the lunch break but the pitch did not relent in giving support to the Mumbai bowlers.

Shankar, who began well with a flurry of fours, was tested consistently outside the off-stump by Deshpande, who kept moving the ball away from the right-hander.

Deshpande’s hard work resulted in a breakthrough for Thakur who had Shankar caught at the second slip by Shams Mulani for a 109-ball 44 which featured eight fours.

Having shown a little interest in getting runs, Shankar’s departure forced Sundar to get a move on.

While he was mostly resolute in defence, Sundar also had luck favouring him twice.

An outside edge off Shardul had Shreyas Iyer spilling a tough chance on 11 and when he reached 37, Musheer spilled a catch at cover.

Mohammed Mohammed smacked three fours in a row of Thakur towards the end to make it 22 runs from one over, which gave a big push to the visitor’s total.

Brief scores: Tamil Nadu 146 in 64.1 overs (Vijay Shankar 44, Washington Sundar 43; Shardul Thakur 2/48, Tushar Deshpande 3/24, Tanush Kotian 2/10) lead Mumbai 45/2 in 17 overs (Bhupen Lalwani 15, Musheer Khan 24*; Kuldeep Sen 1/25, SaiK Kishore 1/3) by 101 runs.
