It was the shot of a veteran baseball slugger, not of a 14-year-old facing his first ever ball in the world's biggest and most-watched cricket league.
So began the elite career of a kid who, for many, is the greatest sporting prodigy of this generation.
Perhaps any.
"Truly God's gift to Indian cricket," was the description the great Sunil Gavaskar has given to Sooryavanshi, whose cherubic face belies the ferociousness with which he has been striking the ball in the glitzy, pressure-filled environs of the Indian Premier League over the past year.
In his recently completed first full IPL campaign, he finished as the top run scorer, hit a record number of sixes and was voted the MVP. Among his prizes was a car, which, of course, he cannot legally drive for three years.
Now aged 15, likened to India cricket icon Sachin Tendulkar and chased by sponsors wanting a piece of cricket's - sport's? - Next Big Thing, Sooryavanshi is going international.
On Friday, the left-handed opening batter will become the youngest ever player in India's senior men's team - 15 years, 91 days - if, as expected, he is picked for the first of two Twenty20 internationals against Ireland in Belfast.
Then comes five T20s in England, where the glare on Sooryavanshi will be even fiercer.
Expect him to take it all in stride.
Last month, former England captain Michael Vaughan told the story of when he bumped into Boy Wonder ahead of an IPL match this season and told him how much he admired the way he plays.
"I said, 'How do you prepare for matches?'" Vaughan recounted on the "Stick to Cricket" show. "And he went, 'Watching cartoons.' I said, 'What do you eat?' He went, 'Everything.'
"There's the modern player: Watch a cartoon, eat what you want, smack it out of the ground."
Sooryavanshi hails from Tajpur, a small agricultural town in the northern state of Bihar between the Ganges River and the border of Nepal.
His father, Sanjiv, was a cricket lover and he gave his middle son of three a bat at the age of 4. By the time he was 10, Vaibhav had been making early morning trips to a Next Gen academy around 100 kilometres away and his prodigious talent was clear, especially the way he hit the ball so fiercely and cleanly and with such a high back-lift that it reminded onlookers of West Indies great Brian Lara.
Sooryavanshi made his debut in elite senior cricket at age 12 - for Bihar in the Ranji Trophy - and, at 13, became the youngest player to get an IPL deal when Rajasthan Royals bought him for the 2025 season for $A1.6 million.
His first IPL shot - that mighty six over extra cover off India fast bowler Shardul Thakur - underlined his status as the next Tendulkar, as did a 35-ball century, which was the second-fastest in IPL history, in his third match.
A star was born.
Watch Sooryavanshi - thick set with strong arms and a side-parting in his dark hair - and what immediately stands out is his uncanny ability to strike the ball hard and far, wherever it is bowled at him.
It's down to a technique that typically sees him get back and across in his crease, dip his shoulder, deliver a high back-lift at a 45-degree angle, keep his arms away from his body and, with remarkably coiled wrists, follow through with a shot generating enormous power.
The kid is making the world's best fast bowlers look silly, including smashing Jasprit Bumrah and Pat Cummins for six off the first delivery of their spells in the IPL.
After being named MVP in the IPL, Sooryavanshi said he wanted to play all three formats for India "in such a way that I should not just play but dominate for 10-20 years".
Big words, and he's backing them up.
In February, he helped India to the trophy in the Under-19 World Cup, smashing 175 off 80 balls in the final against England - the highest individual score in any ICC global tournament final.
Playing for India A on Sunday, he brought up a half-century in 11 balls - the fastest ever fifty in 50-over cricket, according to the BBC - in a knock of 94 off 29 balls against Sri Lanka A featuring just one dot ball.
If he's picked against Ireland on Friday, Sooryavanshi will be the youngest player in a top-tier men's T20, breaking the record of Ireland's Joshua Little (16 years, 309 days). Tendulkar was 16 years, 205 days when he made his test debut in 1989, then made his ODI debut 33 days later.
There's been only one younger player than Sooryavanshi in men's international cricket and that's Hasan Raza, who was 14 years, 227 days when he made his Test debut for Pakistan in 1996.
In 2020, the International Cricket Council set the minimum age of 15 for players to compete internationally.
