At stumps, Hyderabad were 51 for 3 with Kolla Sumanth unbeaten on 34.
Siraj grabbed 4 for 42 in 15 overs as India international KL Rahul was castled by medium pacer Ravi Kiran for 4 runs. He looked rusty during his 27-ball stay at the crease.
Hosts Karnataka after a good batting show in the previous game faltered badly with only Stuart Binny's 61 off 88 balls adding some semblance of respectability to the total.
Siraj hit the deck hard and got the deliveries to jag back into right-handers after pitching. He removed his India A teammate Ravikumar Samarth (19) and also breached through the defences of IPL specialist Mayank Agarwal (0), whose questionable technique was again exposed thoroughly.
