Delhi's Manav Jaini, Rajiv Datar of Pune and Chikkarangappa S of Bangalore were two strokes behind Baisoya in joint second place.
Baisoya, playing his first season as a professional, made a dream start to the week with an amazing run of nine birdies against a lone bogey. The talented 17-year-old birdied the first hole with a seven-feet conversion and followed that up with an astounding 30-feet birdie putt on the sixth. Baisoya suffered a minor blip as he bogeyed the seventh.
Baisoya, who so far has one top-10 on the PGTI, said, "I was hitting it straight and that gave me a lot of confidence. I had a tremendous run of four successive birdies on the eighth, ninth, 10th and 11th that spurred me on further.
Jaini stitched together a fantastic bogey-free round to be placed joint second at six-under-66. He made a 15-footer for birdie on the seventh and narrowly missed two eagle opportunities on the 10th and 11th. Jaini's shot from 90 yards out stopped at the lip of the hole on the 10th and his chip from the edge of the green lipped out on the 11th.
