Left-hander Pant, who is in the IPL wishlist of many franchises in the upcoming auction on February 6, hit nine fours and five sixes during his fastest 50 in the U-19 World Cup history as India cruised to the victory target of 170 in only 18.1 overs.
Nepal, who have been the surprise package of the tournament, were blown away as Rishabh and skipper Ishan Kishan (52)-- both Ranji Trophy players -- added 124 runs in 9 overs giving the 1500 odd people some breathtaking shots to savour.
Earlier, Indian bowlers, led by Avesh Khan (3/34), restricted the Himalayan nation to 169 for 8 in a match that was reduced to 48 overs. Washington Sundar and Mayank Dagar also got a couple of wickets each.
