Shillong Lajong rode on a double strike from Dipanda Dicka to beat Mumbai FC 3-1 in a fifth I-league round match at the Nehru Stadium here on Saturday.
This was Lajong's second straight win of the season while Mumbai slumped to their third defeat on the trot.
Dicka gave the home side the breakthrough in the 28th minute and followed it up with another goal three minutes before the half-time break.
Later, Chinglensana added a third in the 70th minute to seal the tie for the hosts.
For Mumbai, Karan Sawhney scored the lone goal in the 56th minute.
A counter attack by Lajong in the 25th minute saw Samuel Shadap's chip shot being somehow tipped over by goalkeeper Laxmikant Kattimani.
In the 42nd minute, following a Mumbai defensive lapse, Dicka was left alone on the left and went past the advancing goalie to convert with ease.
The two sides went into the break with the score 2-0 in favour of Lajong.
Crossing over, despite the initial pressure exerted by the home side, Mumbai chipped in a goal against the run of play with super-sub Karan Sawhney converting one from close range.
Hopes of a strong Mumbai comeback was, however, shattered in the 70th minute when Chinglensana netted the third goal for Lajong. Chinglensana spun over to put the ball into the back of the net following a corner kick much to the delight of the 5000-strong home crowd.
Things became worse for the visitors when their custodian Laxmikant Kattimani was shown the red card for handling the ball outside the box.
Lajong grabbed full three points from their second win in as many games. Following the victory, Lajong catapulted to the fifth spot in the
league table while Mumbai slipped to sixth.
