Spin duo of Shams Mulani and Tanush Kotian exploited the conditions beautifully to trigger a stunning batting collapse as Mumbai registered a handsome 232-run win after skittling out Kerala for 94 in their Ranji Trophy Group ‘B’ match here on Tuesday.

On a turning fourth day wicket, the home side crumbled under relentless pressure with left-arm spinner Mulani returning with 5-44 from his 16 overs. Off-spinner Kotian provided the perfect support, claiming 5-1-6-2.
