Axar Patel ahead of India's 'designated finisher' Dinesh Karthik in the second T20 against South Africa but top-order batter Shreyas Iyer defended the strategy, saying the need of the hour was to "rotate strike". India were struggling to get going and were 112/6 when Axar Patel got out in the 17th over, and it was mainly due to the veteran Karthik's cameo while batting at No. 7 that they could post a respectable 148/6. "It's something we had strategised earlier as well. We had seven overs left when Axar went in, and he's someone who can take the singles and keep rotating the strike," Shreyas said at the post-match media interaction on Sunday.
