Chasing 405, Saurashtra resumed their second innings at 30 for one and straight away started to lose wickets at regular interval to fold for less than 100 runs.
Both overnight batsmen -- Snell Patel (20) and Robin Uthappa (12) -- fell cheaply, and Saurashtra could never recover from that stage.
Sheldon Jackson was the lone batsman to show some resistance with 24 runs off 74 balls but others failed to put up any fight.
Saxena ended with impressive figures of four for 29, while Akshay (3/23) and Joseph (3/27) chipped in with three wickets each to ensure Saurashtra could not make a comeback.
Kerala: 225 & 411 for six declared. Saurashtra: 232 & 95 all out in 51.3 overs (Sheldon Jackson 24; Jalaj Saxena 4/29, KC Akshay 3/23, Sijomon Joseph 3/27).
