Defending champions Mumbai made a confident start to their Syed Mushtaq Ali Trophy campaign, defeating Railways by seven wickets, with India players Ajinkya Rahane and Suryakumar Yadav making vital contributions in a Group ‘A’ match here on Wednesday.

Chasing a below-average score of 158 for 5 in 20 overs, Mumbai had little trouble overhauling it with Rahane clobbering a 33-ball 62, studded with four boundaries and five sixes, at the top to help the star-studded side finish the chase with 25 balls to spare.
