Karnataka posted an emphatic 117-run win over Jammu and Kashmir while Railways had to settle for first innings points against Pondicherry on the fourth and final day of their Ranji Trophy Elite Group C matches on Sunday. India pacer Prasidh Krishna, who picked six wickets in the first innings, bagged four more scalps to end with a 10-wicket haul (10 for 94) as Karnataka bowled out J&K for 390 despite a stubborn century by captain Ian Dev Singh Chauhan (110 off 188 balls, 15 fours, 2 sixes). Resuming at the overnight score of 190 for 4, J & K continued to fight through Ian Dev Singh and Abdul Samad, who made a belligerent 70 (78 balls, 6 fours, 5 sixes).
