Kolkata: I-League top scorer Ranty Martins struck twice as United SC drubbed ONGC 3-1 to end their campaign with a fourth place finish at the Kalyani Stadium on Saturday.
The Nigerian striker, who topped the scoring chart with 26 goals, converted a 29th minute spot kick and went on to pump in one more at the break.
New Zealand recruit Kayne Vincent`s header in the 57th minute sealed the issue for the purple brigade while Lalmuanpuia reduced the margin with a freekick in the 70th minute for ONGC.
United SC finished with a tally 44 points behind third-placed East Bengal while ONGC remained on 31 points.
United SC should give credit to goalkeeper Subrata Paul for thwarting a fine effort from Lalmuanpuia who unleashed a low and powerful shot in the eighth minute.
ONGC had another fine attack through an Eric Brown left-footer in the 14th minute but Paul once again stood tall under the bar.
In the 28th minute, Vincent was brought down inside the box by Odeola as a penalty was awarded to the home team with Martins making no mistake.
In the first-half added time, Martins added one more when he beat the offside trap for his second goal.
Deepak Mondal set it up for Vincent with a fine cross as the New Zealander comfortably nudged it home.
The unlucky ONGC finally got one goal when Lamuanpuia scored from an indirect freekick that sailed into the United net.
