Michael White thrashed Ricky Walden 5-0 to win his first world ranking title at the Indian Open in Mumbai.
The Welshman, 23, followed up his first professional title at the Shoot-Out in Blackpool last week with a whitewash of England's Walden.
White opened with breaks of 81 and 77, and conceded just 27 points in total.
He had earlier beaten compatriot Mark Williams 4-2 in the semi-finals, while Walden edged out Thailand's world number 61, Thepchaiya Un-Nooh, 4-3.
White will move from his current ranking of 21 to within sight of the top 16, having never previously been beyond the quarter-finals of a ranking event.
"Ever since I first played snooker at the age of seven, I have dreamed of winning tournaments," White told World Snooker.
"It means everything to me, I can't describe how I'm feeling. Since I was nine, people have been on my back to win titles, although the only pressure I feel is what I put on myself. I just want to keep improving now.
"I know it was a quick final but my nickname is 'Lightning', so now you know why!"
