Put in to bat by Kerala, Hyderabad managed to go past 200 only because of some late contributions after being reduced to 78 for six.
A Ashish Reddy's 65-ball 55, including seven fours and a six, and Habeeb Ahmed's 100-ball 39 were the crucial contributions which gave some respectability to Hyderabad's scorecard.
Warrier ended the day with brilliant figures of five for 38 in 19 overs, including eight maidens.
