Abhimanyu Mithun claimed a third five-for of the season as Vidarbha collapsed for 185 before Karnataka were left reeling at 36 for three on the opening day of their Ranji Trophy semi-final, here today. Mithun returned with brilliant figures of 16-6-45-5, his 11th five-wicket haul, and was finely aided by skipper R Vinay Kumar (2/36) as Karnataka bundled out Vidarbha under 200 in 61.4 overs. But the eight-time Ranji champions were tottering at 36 for three in 14 overs when bad light stopped play. Karnataka still trail Vidarbha by 149 runs with four days play still remaining.
