Karun Nair's 52-ball 111 helped Karnataka flatten Tamil Nadu by 78 runs in Vizianagaram to hand them their first loss in the South Zone group. Nair's maiden T20 hundred came a day after his 42-ball 77 powered Karnataka to a controversial two-run win over Hyderabad.

After Tamil Nadu elected to bowl, Karnataka lost opener Mayank Agarwal and No. 3 K Gowtham with only 14 runs on the board. But, Nair raised 83 runs in 47 balls in the company of R Samarth (19) and revved up the innings. Nair was the one-man hit machine for Karnataka, with only two of his team-mates reaching double figures. Seamer Athisayaraj Davidson ran through the lower order to finish with 5 for 30 even as Karnataka finished with 179 for 9.

Tamil Nadu's innings never took off as they lost wickets at regular intervals. Only Washington Sundar, opening the batting, made a handy contribution with a 26-ball 34 that included three fours and a six. Legspinner Praveen Dubey finished with an economical 4 for 19 from 3.3 overs.

An all-round bowling effort helped Delhi restrict Jammu & Kashmir to 100 for 9 and complete an eight-wicket win with 8.3 overs to spare at the Feroz Shah Kotla. Opting to bowl, Delhi's seamers removed openers Ahmed Bandy and Jatin Wadhwan with the score on 0. While captain Parvez Rasool struck a 26-ball 37 and tried to stem the rot, his dismissal in the 15th over led to slide for J&K. Delhi captain Pradeep Sangwan (2 for 16) and Navdeep Saini (2 for 14) chipped away at the top order, before left-arm spinner Pawan Negi picked up three wickets in the middle order.

There was hardly any hiccup in Delhi's chase as openers Rishabh Pant and Sarthak Ranjan raised a 77-run stand in only 8.3 overs. While Pant smashed a 33-ball 51 with seven fours and two sixes, Ranjan, a controversial selection, struck 31 off 20 balls.
