Aditi, who has already won the Fatima Bint Mubarak title in Abu Dhabi, is seeking a Desert Double and is now five-under 139 and five shots behind the leader Anne Van Dam (69-65) of the Netherlands.
What was particularly pleasing for Aditi was that it was a bogey free round with two birdies on either side of the turn. She had birdies on second and third and then 17th and 18th. In between she did miss a few birdies, but also saved some pars nicely.
Aditi was second last year when she was a rookie and she emerged as the Rookie of the Year.
A change of putter worked wonders for long-hitting Anne Van Dam, who blitzed the front nine to move atop the leaderboard.
Starting the second round two shots off the pace, the 22 -year-old Dutch star fired a flawless seven-under 65 to reach 10-under for the tournament, a good two shots ahead of Scotland's Kelsey MacDonald.
