Medium pacer Nizar Niyas scalped six wickets to help Kerala gain the first innings lead over hosts Goa in their Ranji Trophy Group C match, here on Monday.
Kerala were 31-run ahead in their second innings with Nikhilesh Surendran (0 batting) and VA Jagadeesh (0 batting) in the middle when stumps were drawn for the day.
Niyas shone with six for 82 as Goa were bowled out for 242 in response to Kerala's first innings total of 273.
Earlier, Goa who resumed on 11 for no loss, lost opener Swapnil Asnodkar (13) to Niyas in the first session.
Other opener Amogh Sunil Desai (49) and Sagun Kamat (96) added 117 runs for the second wicket as Goa looked well on course to surpass Kerala's first innings score.
But Niyas triggered a Goan collapse as he sent back Desai, Rohit Asnodkar (1), Ravikant Shukla (0) and Keenan Vaz (0) in quick succession to leave the hosts tottering at 143 for five.
Kamat missed out on a well-deserved century by just four runs as he was caught by Surendram off Rohan Prem with the score on 162. His 155-ball knock was laced with 13 fours and a six.
None of the other batsmen offered any resistance and the side was dismissed for 242.
Apart from Niyas, Prem also accounted for two wickets.
Kerala: 273 and 0/0 in 1 over
Goa: 242 all out in 91.2 overs (Sagun Kamat 96, Amogh Sunil Desai 49; Nizar Niyas 6/82, Rohan Prem 2/10).
