The hot-in-form Ronchi scored 67 off 35 with eight boundaries and three sixes on 191.42 strike rate, neurtralising the Kings’ pace attack led by Muhammad Aamir and Usman Shinwari.
The only brief relief to the Kings was provided by skipper Imad Wasim, who dismissed Sahibzada Farhan and Hussain Talat in his over. Igniting chance of a comeback which was swiftly quashed by Ronchi’s onslaught.
Samit Patel assisted the team with his valuable 44 runs innings.
Ben Dunk and Aamir Yameen’s death over slogging gave a saving grace to the Imad Wasim-led Karachi Kings by taking the team to 143 runs after a shambolic batting collapse against Islamabad United.
Dunk scored 49 off 32 balls with two boundaries on 153.12 strike rate, while Aamir Yameen played a knock of 39 off 20 with three boundaries and two sixes.
Opener Babar Azam scored 27 off 21 with 4 boundaries in an innings dominated by spectacular bowling display of Faheem Ashraf who picked three wickets off 26 runs.
Meanwhile, for Kings, youngster Muhammad Musa and Rumman Raees picked one wicket each.
Imad Wasim-led Kings currently sit at the bottom of the points table after having accumulated just two points from three games, while United have four points from four games.
The Kings who had kicked off their PSL campaign on a winning note against Multan Sultans lost their next game by 22 runs to Lahore Qalandars, and then by 44 runs to last year’s runner-up Peshawar Zalmi.
United also started the tournament with a five-wicket against Qalandars but lost their next game to Sultans by five wickets, followed by a seven-wicket thumping at the hands of Quetta Gladiators. The Mohammad Sami-led team, however, changed things around and beat Zalmi by 12 runs.
With Mohammad Amir leading the bowling attack for Kings and Umer Khan in the midst, Karachi will defiantly have plenty to work with.
