A sudden middle-order collapse triggered by spinners Shams Mulani and Tanush Kotian put Mumbai on the verge of an Irani Cup win despite Abhimanyu Easwaran’s heroic 191. Prithvi Shaw (76 off 105 balls) then came out all guns blazing as the ball started turning square with Mumbai finishing the day at 153 for 6 with an overall lead of 274.
