Kolkata chased down their target of 156 in 15.1 overs in Abu Dhabi
Eoin Morgan's Kolkata Knight Riders won their second straight Indian Premier League match with a seven-wicket thrashing of holders Mumbai Indians Thursday to move into the top four.
Opener Venkatesh Iyer smashed 53 and put on an attacking second-wicket partnership of 88 with Rahul Tripathi, who made an unbeaten 74, as Kolkata chased down their target of 156 in 15.1 overs in Abu Dhabi.
Iyer has made an early impact in the revived Twenty20 tournament after his match-winning unbeaten 41 in the team's previous win over Virat Kohli's Royal Challengers Bangalore.
Morgan's team jumped to fourth in the eight-team table led by Delhi Capitals.
Left-hander Iyer reached his 50 off 25 balls to take apart the Mumbai bowling led by New Zealand left-arm quick Trent Boult.
He fell to pace bowler Jasprit Bumrah but Tripathi kept up the charge in his 42-ball blitz laced with eight fours and three sixes.
Five-time champions Mumbai started strongly with a 78-run opening stand between skipper Rohit Sharma, who scored 33, and Quinton de Kock, who made 55.
But Kolkata's bowlers soon hit back to choke the opposition run flow with regular wickets as Mumbai finished on 155 for six after being invited to bat first.
New Zealand's Lockie Ferguson and fellow quick Prasidh Krishna took two wickets.
West Indies spinner Sunil Narine returned economical figure of 1/20 from his four overs, getting the key wicket of Rohit.
He was named man of the match.
It was a forgettable return for Rohit who had missed the team's previous loss against Chennai Super Kings when the IPL resumed Sunday in the United Arab Emirates.
The tournament had a scare Wednesday when Hyderabad left-arm quick Thangarasu Natarajan tested positive for coronavirus and isolated with six other close contacts but their match against Delhi went ahead.
The IPL was halted in May because of pandemic deaths in India, prompting foreign players to rush home and many have not come back including England's Ben Stokes (Rajasthan Royals) and Pat Cummins (Kolkata) of Australia.
