MILAN (AP) Italian teenager Jannik Sinner beat top-seeded Alex de Minaur in straight sets at the Next Gen Finals on Saturday to claim his first ATP title - and a big payday.

Wild card Sinner triumphed 4-2, 4-1, 4-2 in the final, serving out to love and clinching victory when De Minaur hit a return into the net, much to the delight of a boisterous crowd in Milan.

It was a second successive runner-up finish for De Minaur, at the season-ending tournament for top under-21 players.

The title caps a fantastic season for the 18-year-old Sinner who opened the year at No. 551 but is now the youngest player inside the Top 300, having risen to No. 95.

He only recorded his first ATP Tour main-draw win in April.

Sinner picked up $372,000 from this week's tournament, surpassing his career total before arriving in Milan.

And ''Sinner-Mania'' is sure to grow. His run in Milan has stirred the crowds this week to near-hysteria and fans have packed the stands just to watch him practice.

Sinner dominated from the start and, after the opening games had gone with serve, broke to love to take the first set.

Roared on by his home crowd, Sinner never looked back and again broke De Minaur's serve at his first opportunity in the second set.

De Minaur managed to save a set point on his serve but that was simply delaying the inevitable as an imperious Sinner served it out to go 2-0 up.

And the noise grew to fever pitch when Sinner broke again in the third game of the final set.
