Cuttack: Uttar Pradesh middle-order batsman Umang Sharma's unbeaten 47 upstaged a brilliant 78 by Shreyas Iyer as Uttar Pradesh stole a tense four-wicket win against big guns Mumbai in the Group D Twenty20 cricket match of the Syed Mushtaq Ali Trophy here today.

Chasing 165 for a win at the Barabati Stadium, UP top-order batsmen squandered away good starts only to see Umang stay on with his 32-ball blitz and help the side achieve the target with two balls to spare.
