Umran to bowl his fourth over as India look for their first breakthrough.
Conway clips the second ball for a single to midwicket and Allen nudges the next to fine leg for another run.
Conway drives a wide half-volley with some good timing but straight to the fielder in the covers and the next is driven straight to mid-on.
After an expensive start, Umran has got back some control conceding just six in his last two overs.
Sundar continues as Allen and Conway take a single each before the former swats a short ball over long-off for a six, to race to his fifty from as many balls and keeps strike with one from the last ball.
Umran brings India some relief with the wicket of Allen, who is caught in the covers after a superb innings of 57 from 54 balls.
He looks to smash the short wide straight into the hands of Suryakumar in the covers as he gets it off the bottom of the bat, to end the 97-run opening stand with Conway.
Kane Williamson gets a beauty first up, the short of good length delivery moving away enough to go past the edge.
