Kerala's only loss in the group stage was at the hands of Karnataka.
Kerala rode on the consistent performances of senior players Sachin Baby, pacer S Sreesanth and outstation professionals Robin Uthappa and Jalaj Saxena to progress from a tough group.

This was Kerala's second victory on the trot in Elite Group C.
Kerala's outstation professional Jalaj Saxena was picked up by Punjab Kings for his base price of Rs 30 lakh.
Leggie Rojith is the surprise entry, while pacer Sreesanth missed out.
Sachin Baby will lead Kerala in the forthcoming Vijaya Hazare Trophy.
Pacer S Sreesanth is also part of the 20-member team.
Royals, with Sanju at the helm, will be tempted to rope in young opener Mohammed Azharuddeen. However, other teams too will be keen on signing 'Junior Azhar'.
