Captain Shreyas Iyer and senior batsman Ankit Bawne hit patient half-centuries as India 'A' recovered after a few early wickets to draw the second unofficial Test match, which helped them win the two-match series against South Africa 'A' 1-0, in Bengaluru on Monday.
India 'A' won the first four-day match by an innings and 30 runs.
Starting the final day on 294 for seven, the Proteas added 25 runs losing the remaining three wickets to be bowled out for 319 in 98.2 overs.
Mohammed Siraj (4/72) and Ankit Rajpoot (3/52) shared bulk of the spoils while limited overs specialist Yuzvendra Chahal grabbed two for 84 in 22 overs.
With a slender 26-run lead, India 'A' finished their second essay at 181 for 4 with Iyer (65) and Bawne (64 no) steadying the ship with a 86-run stand for the fourth wicket.
Iyer hit four boundaries and four sixes in 103 balls while Bawne hit nine boundaries in 100 deliveries.
This was after Prithvi Shaw (4) and Mayank Agarwal (28) were dismissed cheaply.
"I am happy that I got some runs under my belt. For sure, there was nothing wrong in my batting in the last two innings, just that I needed to convert 30s into big scores, which I tried focussing on," Iyer said after the match.
The match was called off at tea after it rain forced the plays off the field.
