Chennai were 91-1 after ten overs, with Ambati Rayudu and Suresh Raina going well. The 71-run stand was broken by Krunal Pandya, but even then, Chennai were favourites to close in on 200, with the in-form Mahendra Singh Dhoni blazing away after a brief settling-in period.However, the 18th over, sent down by Mitchell McClenaghan, changed everything. He was fortunate to dismiss Dhoni, the India veteran picking out the fielder in the deep off a wide full toss. But he extracted extra bounce to cramp Dwayne Bravo two balls later, and the all-rounder holed out.With two big hitters dismissed in the death, Chennai were limited to a score 10-15 runs below par, according to their coach Stephen Fleming. Mumbai won by eight wickets, with all of Suryakumar Yadav (44 off 34), Evin Lewis (47 off 43) and Rohit Sharma (56 off 33) getting among the runs.As for Chennai, they remain on top of the table, despite the loss – their second of the campaign. Fleming admitted the 18th over from McClenaghan was the turning point, but he took comfort in the fight displayed by his side.He stressed that Chennai shouldn’t get affected by the loss, and pointed to the fact that they didn’t really have home advantage anymore, given the shift in venues from Chennai to Pune.“We’ve got to be careful we don’t get too carried away by a loss,” he said. “We’ve done well up to this point, the guys contributed well. But this is a good time, halfway through the tournament, to have a look at what is best. The biggest thing for us is getting to know this pitch. It’s not Chennai, so keep in mind we picked a side that was going to be Chennai-based (in the auctions). We’re learning as much as anyone, it’s only our second game out there. We’ve got to work extra hard for home advantage.”
