Defending champions Karnataka stormed into their fourth successive Vijay Hazare Trophy semi-finals with a thumping 54-run victory over Mumbai via the VJD method here on Monday.

With the tournament’s leading run-getter Devdutt Padikkal (81 not out; 95 balls, 11x4) and veteran India batter Karun Nair (74 not out; 80 balls, 11x4) unbeaten, Karnataka were cruising at 187-1 in 33 overs while chasing a modest 255 when rain stopped play.
