Umran Malik's scorching final over proved to be the difference as Sunrisers Hyderabad slayed Punjab Kings by seven wickets for their fourth successive win in the Indian Premier League on Sunday. In top gear with Liam Livingstone's counter-attacking 60 off 33 balls (5x4, 4x6), PBKS lost five wickets in seven balls with Malik (4/28) producing a perfect final over -- a rare four-wicket maiden -- to skittle out the opposition for a below-par 151. As it happened | Scorecard | Points TableAfter Bhuvneshwar Kumar (3/22) provided the key breakthrough of Livingstone, the 22-year-old uncapped pacer picked three wickets while the fourth came via run out to derail PBKS. In reply, Sunrisers Hyderabad did not have a perfect start and lost skipper Kane Williamson (3) early in the fourth over with Kagiso Rabada drawing the first blood. Opener Abhishek Sharma (31 off 25 balls; 3x4, 1x6) and in-form Rahul Tripathi (34 from 22b; 4x4, 1x6) failed to convert their starts but the modest total meant that SRH did not have to worry much in the end.
