Siddikur Rahman needed just four holes of the final round to overhaul S S P Chawrasia at the top of the Hero Indian Open leaderboard.
Chawrasia had looked on course for a third European Tour title on home soil after a run of 52 holes without a bogey at the tight, tree-lined Delhi Golf Club helped him establish a two shot lead going into the final day.
But after pars at his first two holes, the 36 year old - a two-time winner at this venue – paid the price for a wayward tee shot into the trees at the third with a bogey.
It got even worse at the next, with the World Number 204 again finding forest from the tee and this time having to take a penalty drop en route to a double bogey.
That meant fellow course specialist Siddikur needed just four straight pars to take over the lead on ten under par, with Chawrasia a shot further back and a host of players suddenly finding themselves in contention.
Australian Marcus Fraser birdied the long first and made excellent up-and-downs at the third and fourth to sit third on eight under par, alongside home favourite Anirban Lahiri – the highest-ranked player in the field.
The recent Maybank Malaysian Open winner birdied the first from 15 feet and only needed a tap-in at the next after an excellent approach, before gaining another shot at the short fifth.
Swede Daniel Chopra and Thailand’s Prayad Marksaeng were tied for fifth on seven under par.
Chawrasia needed only a par at the sixth to regain a share of the lead as Siddikur – who already has ten top-ten finishes from 11 starts at this venue – failed to get up-and-down from the side of the green.
Fraser also dropped a shot after finding a near-unplayable lie with his approach, while up at the short seventh Lahiri bogeyed after missing the green to leave the leading pair two clear.
Chawrasia dropped a shot from the bunker at the seventh, but got it straight back with a lengthy two-putt at the par five next.
Fraser also gained a shot at the eighth after chipping to two feet to reach the turn only one behind the leading pair, who were immediately separated on the tenth when 30 year old Siddikur three-putted the tenth for a bogey.
Having retaken the lead, Chawrasia looked to have a chance of doubling it at the 11th when he fired his approach to ten feet and both Siddikur and Fraser missed the green.
But while Siddikur bogeyed, Fraser – whose last European Tour victory came in 2010 – chipped in for birdie and with Chawrasia only making a par the two were tied for the lead on nine under, with Lahiri and Siddikur two behind.
