Shreyas Iyer smashed a 139-ball 178 to put Mumbai in a position of dominance on the opening day of their Ranji Trophy Elite Group 'A' encounter against Baroda yesterday.

The hosts piled up 439 for eight by stumps at the Wankhede Stadium thanks to centuries from Iyer and skipper Siddhesh Lad. Iyer rescued his struggling side a day after landing in Mumbai from Mount Maunganui, New Zealand where he represented India 'A' against New Zealand 'A' in a one-day series.
