If Pant was the top-scorer with 34-ball 61, then his younger colleague and India U-19 World Cup team member, Abhishek Sharma, hammered 46 off just 19 balls on his IPL debut to take his team to a respectable total.
RCB had won the toss and had elected to bowl first. The 17-year-old innings comprised four sixes and three boundaries.
RCB fielded Indian all-rounder Sarfaraz Khan in place of Manan Vohra. Aussie Glenn Maxwell has failed to contribute with bat and ball.
Chahal got rid of Jason Roy - the other Delhi opener - in his next over with a sharply incoming delivery that totally bamboozled the England batsman before going on to disturb the stumps.
With RCB in a do-or-die situation, we could expect them to pull this one off against the Delhi based franchise, who have virtually been knocked out of the tournament.
But the man who took the pitch next was Rishabh Pant, and the 20-year-old started in a manner which seemed to proclaim that he would once again be living up to his hard-hitting reputation.
With the asking rate hovering around 8.5 runs an over, de Villiers and Kohli took on Harshal Patel in the 13th over to take 19 runs off their former teammate which brought the equation down to 50 off 42.
Rahul continued his scintillating form in the IPL by smacking two fours and seven sixes as Punjab's top order crumbled around him. Off-spinner Moeen Ali finally brought the rampage to an end when Pant attempted another big hit, only to be caught by AB de Villiers near the boundary rope wide of long-on.
Arsenal hit with FA charge for failing to control players
The Frenchman will take charge of his final Arsenal game on Sunday, bringing down the curtain on nearly 22 years at the helm. The Frenchman also stated that he wanted his club to organize a tour to the country but the plans never materialized.
Pant's dismissal also ended his partnership of 93 off 62 with captain Shreyas Iyer. The right-hander had attempted to smash pacer Mohammed Siraj over the onside, but his mistimed shot could only manage to find RCB skipper Kohli. With that Delhi were at 120 runs for the loss of four.
The innings gathered momentum when Pant hit Mohammed Siraj for consecutive sixes - one off the back foot and the other off the front - in the eight over, which was the paceman's first of the night.
The veteran South Africa batsman, on the other hand, struck four boundaries and six maximums in his knock and remained unbeaten till the end.
Kohli looked relaxed ahead of the must-win game as he went out for dinner with teammates in his home city. Lamichhane too stood out with his performance as he took Parthiv Patel's wicket and conceded 25 runs in four overs.
Chennai Super Kings skipper Mahendra Singh Dhoni has already experienced fanboy moments during the eleventh edition of the Indian Premier League, thrice and on Saturday it was chance for Virat Kohli to enjoy some.
OUT! Poor start for RCB.
The team has always relied heavily on Kohli and AB de Villiers but it is high time the likes of Mandeep Singh, Quinton de Kock and Brendon McCullum deliver. Tim Southee was the unfortunate bowler who eventually leaked 22 runs in the 17th over with Sharma smashing him for two sixes in a row.
