After skipper Dinesh Karthik's attacking 183, it was pacer Chandrasekar Ganapathy who shone with the ball to steer South Zone to a commanding position against West Zone on Day 2 of the five-day Duleep Trophy final in Hyderabad on Wednesday.
Ganapathy rattled the top order, claiming five wickets for 75, as West were dismissed for 251 in their first innings, built mainly around Yusuf Pathan's breezy 108.
At the end of the second day, South had extended their overall lead to 191.
In their second essay, South were 42 without loss, with S Anirudha (23) and K Pawan (14) at the crease.
Earlier, South's first innings folded for exactly 400, after adding just 44 runs to their overnight score, with Karthik contributing 23 runs.
Irfan Pathan was the most successful bowler for West, scalping five wickets for 100.
