The 20-year-old bowler is one of the three young players named in the 14-man squad last weekend for the International Cricket Council (ICC) Champions Trophy.
Kenya had won the toss and scored 231 for eight, with a contribution of 67 by middle order batsman Hitesh Modi from 92 balls. Skipper Steve Tikolo contributed 38.
In reply, India 'A', under former Kenya coach Sandeep Patil, had a shaky start with an opening stand of 18 between openers Mohindu Singh Dhoni (8) and Gautham Gambhir (10). Ramesh Powar was the highest scorer for India with 80 runs off 58 deliveries.
But Aga had a good line-and-length in his controlled bowling. In his 4.2 overs spell, he bowled one maiden and gave away only 18 runs.
Kenya beat Pakistan 'A' by two runs in the opening match of the series on Wednesday to put their Champions Trophy preparations on the right path. The two teams meet again on Friday.
