Shreyas Iyer's 51-ball 86 run blitzkrieg helped Mumbai sail past a tall Vidarbha total to notch up a five-wicket win in the Super League phase of the Syed Mushtaq Ali T20 Group A match in Mumbai. Chasing Vidarbha's score of 181 for four, built mainly around opener Jignesh Sharma's punishing knock of 56 off just 30 balls, Mumbai cantered home in 18.5 overs to register their second straight victory in as many days in the tournament, at the Wankhede Stadium. Iyer and skipper Aditya Tare (41 in 24 balls) steadied the Mumbai innings after the early loss of left-handed opener Akhil Herwadkar (4) through a brisk second-wicket partnership of 71 runs in 7.2 overs.
