Abhimanyu Mithun (26), Pragyan Ojha (21) and S Aravind (11) chipped in with useful contributions to help South Zone take a healthy 140-run lead.
In their second innings, North Zone were 50 for one with Ojha removing opener Shikhar Dhawan (19). N Saini (21) and Mandeep Singh (9) were at the crease when stumps were drawn at the Dr YS Rajasekhara Reddy ACA-VDCA Cricket Stadium here.
Earlier, resuming their first innings at 298 for three, overnight batsman Badrinath added another 39 runs to his score of 97. He hit 12 fours and a couple of sixes in his 208-ball innings.
Sumanth gave the skipper good support at the other end and cracked seven boundaries before his innings was cut short by Narwal, whose low-bounce ball rattled the timber.
A few overs later, Badrinath was run out by Ishant Sharma after Amit Verma fielded the ball and sent it straight to bowler who made no mistakes.
Ishant struck again, dismissing C Gautam (9) and R Vinay Kumar (0) in consecutive overs at the same score of 386. Joginder Sharma then got rid off Mithun, while Yashpal Singh had Ojha stumped by Uday Kaul.
