Kolkata: Real Kashmir humbled heavyweights Mohun Bagan 2-1 and the giant-killing act, one of many engineered by the debutantes in the ongoing I-League, kept their title hopes alive, here Sunday.
The win against a profligate Mohun Bagan helped Real Kashmir, the first team from the valley to play in India's top-flight, continue their fairytale run.
The team's sixth victory was achieved on the back of a brace by Mason Robertson, who struck in the 33rd and 74th minute at the Salt Lake Stadium.
Starting as a defender, Scottish Robertson, who was recruited by his father and coach of the club David Robertson, dominated the game to hand the former champions a second successive defeat.
League winning star winger Sony Norde, who made a comeback after missing four matches due to his leg injury, scored the solitary goal for the home side in the 42nd minute.
"Today's win is because of dedication and hard work of everyone at RKFC. The boys were exceptional and I am sure that the spirit continues as we begin our final uphill task," said Sandeep Chattoo, co-owner of Real Kashmir Football Club (RKFC).
"The RKFC wishes to place on record its great appreciation towards people of Kolkata for the love showered on us," RKFC owners Chattoo and Shamim Meraj said.
The result also avenged their home leg defeat to Mohun Bagan as they moved up the pecking order, going past NEROCA FC to the second place.
The Snow Leopards now have a three-point deficit against leaders Chennai City (24) in the standings as the father-son duo continued to weave magic for the club.
Mohun Bagan slipped to sixth place with 15 points from 11 matches and saw their title hopes virtually go up in smoke.
The visitors also capped a fine outing in Kolkata after their 1-1 draw against East Bengal, extending their unbeaten run to seven matches in the top-tier league.
Mason, who missed their last match against East Bengal due to food poisoning, quickly switched to the attacking third and make instant impact.
At the halfway mark, the newcomers drew first blood against the run of play when Mason deceived Arijit Bagui in an aerial battle and headed home a cross floated in by Surchandra Singh, stunning the boisterous home crowd.
The Shankarlal Chakraborty-coached side started pressing hard with more urgency after conceding and kept knocking on Kashmir's door for the equaliser.
It paid dividends, as Norde brought the Mariners back into the game with a sublime free-kick, which flew into the top corner.
Mohun Bagan got a chance to snatch the lead moments later with a perfect cross by Henry Kisekka but midfielder Sourav Das' header failed to make an impact.

The 24-year-old Mason, who quit Scottish club Peterhead FC after being roped in by his father on a full-time contract for Real Kashmir, brought up his brace with a thunderbolt strike.
