Khalin Joshi had a steep fall in the third round after he shot six-over 78 to slip from T-23 to T-65 in the Volvo China Open on Saturday.
Meanwhile, SSP Chawrasia (72) was T-59, but the best Indian was Ajeetesh Sandhu (69) at T-39 after 54 holes.
France's Benjamin Hebert stunned the crowd with a sparkling eight-under-par 64 to snatch the third round lead, taking along a three-shot cushion into the final round.
Finland's Mikko Korhonen and Spain's Jorge Campillio took advantage of China's Wu Ashun's slip-up by posting rounds of 65 and 68 respectively to share second place with their three-day total of 14-under-par 202 at the Genzon Golf Club.
Wu was left to rue four costly bogeys which saw him lose his grip on his overnight lead as he slipped to fourth place, four shots back of Hebert with a 72.
Philippines' Miguel Tabuena and Thailand's Tirawat Kaewsiribandit meanwhile returned with matching 65s to give themselves an outside chance of winning in Shenzhen as they are eight shots back of Hebert, in a share of 14th place together with seven other players.
