It was an all-round show from Karnataka where right- arm medium pacer Koushik V shone with the ball and later Mayank Agarwal and Karun Nair remained unbeaten as Karnataka chased the 110-run target with utmost ease.
Karnataka bowlers justified their skipper's decision to invite Delhi to bat first at the Emerald Heights International School Ground.
Koushik (4-19) and leg-spinner K C Cariappa (3-15) wreaked havoc as Delhi was restricted to a meagre 109/9 in their 20 overs.
Apart from Nitish Rana (37 off 29 balls) and Lalit Yadav (33 off 40 balls), no other Delhi batsman showed spine as Koushik and Cariappa rattled their top and middle order.
For Karnataka, medium pacer R Vinay Kumar (1-13) also played his role to perfection.
Wicket-keeper B R Sharath (26 off 15 balls) and ever dependable Agarwal (43 not out off 47 balls) added 32 for the second wicket, but then Sharath was run out by Subodh Bhati.
Karun Nair, who has a triple hundred in Tests, then joined Agarwal as the duo took Karnataka home with 4.3 overs to spare and in the process took the Delhi bowlers to task.
All Delhi bowlers, including test specialist Ishant Sharma (0-7), had an off day in the field.
Meanwhile, in Group A game, Bengal thrashed Jharkhand by 8 wickets.
Bengal bowlers dished a clinical performance to restrict Jharkhand to 126/9 in 20 overs and then chased the target with seven overs to spare.
Shreevats Goswami starred with the bat as he remained unbeaten on 86 off just 50 balls, striking 12 fours and a six to help Bengal grab four points.
In the Group B game, Vidarbha bowlers held their nerves and guided their side to a 10-run victory over Uttar Pradesh.
Maharashtra won by four wickets and amassed all four points.
