Playing for 41-time champions Mumbai, Jaiswal struck a half-century on the opening day of the Ranji Trophy final against Madhya Pradesh in Bengaluru on Wednesday.
Jaiswal said that Buttler, who won the Orange Cap for being the highest-scorer in IPL 2022, advised him to stay focussed and go for his shots at the right time and in the hour of need.
"I try to follow his tips, which have helped me. Watch the ball, understand the situation and keep playing good cricketing shots that I follow," Jaiswal was quoted as saying in a video uploaded on BCCI Domestic's Twitter handle after the end of the first day's play.
Jaiswal has been in great form going into the final as he struck three centuries in a row against Uttarakhand and Uttar Pradesh respectively. He was looking good for a fourth-century before getting out, caught by Yash Dubey off Anubhav Agarwal.
India rode on fifties from openers Yashasvi Jaiswal (50), Divyansh Saxena (55), skipper Priyam Garg (73) and wicket-keeper Dhruv Jurel (59 not out) to cross the line with eight balls to spare.
For Bangladesh U-19, Mahmudul Hasan Joy scored a 134-ball 109 to push his team's total to 262. He hit nine fours and one six in his innings. Mahmudul shared a stand of 65 runs with opener Parvez Hossain Emon (60) before adding 64 runs with Shamim Hossain (32).
However, apart from Tanzid Hasan (26) after that, none of the Bangladeshi batsmen managed to reach double figures. Kartik Tyagi (2/49) and Sushant Mishra (2/33) starred with the ball for India.
By contrast, it was a team effort with the bat from India with four of the six batsmen scoring half centuries.
Brief Scores:
Bangladesh U-19: 261 all out in 50 overs (Mahmudul Hasan Joy 109, Parvez Hossain Emon 60; Sushant Mishra 2/33).
India U-19: 264 for 4 in 48.4 overs (Priyam Garg 73, Dhruv Jurel 59 not out; Rakibul Hasan 2/55).
His well-documented struggles include living in a tent after coming to Mumbai from his native Uttar Pradesh as an 11-year-old. That move was triggered by his desire to make a name for himself in cricket.
He has certainly managed to that.
Jaiswal is currently an under-19 World Cup-bound batsman, ready to represent India in the age-group showpiece in South Africa come January-February.
But before that, he has made heads turn by fetching a rather impressive IPL deal.
"I am very happy. It's a great opportunity for me to learn. I want to learn as much as I can during my time with Rajasthan Royals. It is a platform for me to make a name for myself," Jaiswal said after getting a higher bid than his Under-19 captain Priyam Garg (Rs 1.90 crore, Sunrisers Hyderabad).
The youngster from Suriya village in Uttar Pradesh has been in stellar form, playing for Mumbai in the domestic season.
In the prestigious Vijay Hazare Trophy in September-October, he struck 203 off 154 balls, including 12 sixes and 17 boundaries, to become the youngest batsman to hit a double hundred in List A cricket.
He tallied an impressive 564 runs at an average of 112.80 with three hundred and a fifty during this season.
