The bottom-placed outfit continued their good form at home, defeating an out of sorts Lajong at the Jawaharlal Nehru Stadium.
Foreigners Yusa Katsumi and Eric Brown notched up five star performances with the latter bagging the Man-of-the-Match award for his outstanding display.
Brown opened the floodgates for the hosts in the 19th minute, picking up a C Kenistan ball from the left flank to slot home past the diving Lajong custodian.
Katsumi doubled the lead early on in the second half when he brilliantly dodged past his marker to slam home his first of the match.
The Japanese playmaker capped off what has been a good day in office for him, ten minutes from full time. Playing one two with Brown, Katsumi outfoxed the goalkeeper expertly to seal the lopsided contest.
The visitors had their moments but failed to make the most of whatever little came their way.
In the 13th minute of the match when Lajong had all to play for, Sushil Kumar drilled a free header wide with the goalkeeper out of his line.
Post match, an elated Kashyap said: "It is a great start under me. We played positive football throughout the match. I hope to continue from here."
Courtesy this resounding win, ONGC are now out of the drop zone with 10 points from 12 outings. Lajong remain eighth with 13 points from 12 encounters.
