Hubert Hurkacz spoiled the storybook scenario of teenaged Jannik Sinner with Sunday’s 7-6(4), 6-3 victory over his occasional doubles partner to win the Miami Masters.
Italian Sinner, aged 19 and a former junior ski champion prior to his switch to tennis, was bidding for his first title at the elite Masters level.
But Poland’s Hurkacz, 24, got there first with his debut M1000 win in one and three-quarter hours..
The final was the first between players ranked outside the Top 30 at a Masters since 2005 at Paris Bercy, when 50th-ranked Tomas Berdych beat Ivan Ljubicic, now the coach of Roger Federer.
Hurkacz went up an early break against Sinner, who clawed back the difference but lost the opening set in a tiebreaker shootout.
The Italian trailed love-3 again in the second on two broken serves but was this time unable to close the gap, taking the defeat after losing serve four times and Hurkacz’s first match point.
The Pole remains unbeatable in Florida this season after also winning the Delray Beach tournament in January.
His tropical double pipped the feat of Jan-Michael Gambill from 2001, when the American won Delray but lost to Andre Agassi in the Miami final..
Sinner was the fourth teenager to feature in the Miami final after Novak Djokovic (2007), Rafael Nadal (2005) and Agassi (2000).
