Sanandiya wrecked havoc on the J & K batsmen, dismissing SP Khajuria (8), Ummar Nissar (0) and Pranav Gupta (8) at the top and skipper Parvez Rasool (21) and lower-order batsman Asif Khan (0).
Saurashtra openers Avi Barot (36) and Sagar Jogiyani (41) then returned to produce a 84-run first wicket partnership to give them a good platform.
Once Barot was dismissed by Zahoor Sofi (1/22) in the 17th over and Jogiyani was removed by Sameer Ali (1/50) in the next over, Arpit Vasavada (31) and Sheldon Jackson (35) helped the team grab the first innings lead.
