India's Kshitij Naveed Kaul negotiated the tougher afternoon conditions well enough to return with a one-under 69 on the first day at the Asia-Pacific Amateur Championships.
The 17-year-old, making his third AAC appearance, had four bogeys and three birdies and was lying T-19 in the highly-competitive event, from where the winner gets into next year's Masters and The Open.
Kshitij opened with birdies on his second and third holes but gave away those gains with back-to-back bogeys on fourth and fifth.
A birdie on ninth, a long putt from around 20-22 feet saw him turn in one-under.
On the second nine as the wind picked up it also began raining intermittently but Kshitij played steady for one birdie and one bogey and parred the rest at the New Tanjong Course on Sentosa Island.
Overall, it was a modest day for the other Indians.

None of them came under par, as southpaw Kartik Sharma (71) was T-38th, Yuvraj Sandhu (72) was T-45, Varun Parikh (73) was T-58th and both Rayhan Thomas and Vinay Kumar Yadav with 74 each were T-67th.
David Micheluzzi, the second-best ranked Australian in the event, came to the Par-4 18th at 4-under and sent the crowd into raptures as he dramatically holed his second shot for an eagle.
It handed him the sole lead as Jin Cheng, the 2015 AAC champion, Filipino Lloyd Jefferson Go and Chinese Taipei's Yung-Hua Liu were all 5-under 65.
Micheluzzi said, "Actually I have never had an eagle on a Par-4 at 18th. Also, the rain in the afternoon made it cooler and I felt better."
