Vasco continued their recent good showing, coming back from a goal in arrears to beat Tollygunge Agragami 2-1 in a National Football League match in Kolkata on Monday.
Tollygunge went ahead in the 18th minute when their in-form striker Surojit Bose found the mark.
But the visitors swung the match in their favour by scoring twice within eight minutes in the second session to gain their second back-to-back victory.
Vasco, who were languishing at the bottom of the table with two points from eight matches till they upset three-time champions Mohun Bagan in their last match to register their maiden victory in the current edition of the league, have now bolstered their points tally to eight from ten matches.
Brazilian Sidney Rodrigues and substitute K Anees netted the goals for the Goans.
Tollygunge, who remain on 12 points after 11 outings, drew first blood when a long free-kick by their Ghana player Suley Musah rose high after dropping in the the Vasco box, and Bose showed fine opportunism to head the ball into the net.
Vasco goalkeeper Virender Singh was left stranded as the handful of spectators at the giant Salt Lake stadium celebrated.
The Goans drew parity in the 65th minute as Sidney's rasping 25-yard free-kick bulged the net after getting deflected off the defensive wall set up by the Tollygunge players.
More misery was in store for the locals in the 73rd minute, with Sidney essaying a fine pass to Anees, who scored with a right-footer from outside the box.
