The three-time Asian Tour winner, Chawrasia shot four birdies on the back-nine to get to nine-under 207 overall.
Chawrasia is five shots behind the leader, Hung Chien-yao of Chinese Taipei, who carded four-under 68. Lying second was South African Jbe Kruger (69).
Among other Indians, Rahil Gangjee (70) was Tied-12th at eight-under 208, while the rest of the Indians were way behind. S Chikkarangappa (72) was three-under 213 and tied-44th, Shubhankar Sharma (72) was tied-50th at two-under and Jyoti Randhawa (74) was even par 216 in Tied-54th place. Shiv Kapur (76) and Chiragh Kumar (75) were 63rd and 65th.
"It was less windy when I played today actually, compared to the last two rounds. My playing partner, Sam Brazel, also shot a 67 today. I think both of us rub off the good vibes from each other. I am looking forward to tomorrow now that I've put myself in the mix. I will try my best again tomorrow."
Gangjee had three birdies in first even holes, but then ran out of birdies. A bogey on 13th also set him back and he was eight-under 208 for 54 holes.
Chinese Taipei's Hung Chien-yao birdied three of his last five holes to pull one-shot clear of Kruger. The 23-year-old Hung, the overnight co-leader, jostled with Kruger all day at a sun-kissed Manila Southwoods Golf and Country Club before edging ahead with a four-under 68 and a 14-under 202 aggregate to remain in pole position for a maiden Asian Tour victory.
Thailand's Natipong Srithong fired a fine 66 to move into contention on 206 in tied fourth position with Spaniard Carlos Pigem, who enjoyed a bogey-free 67 in the richest golf tournament in the Philippines.
