Poland`s Hubert Hurkacz defeated Italian teenager Jannik Sinner in straight sets to win the Miami Open and claim the first ATP Masters title of his career on Sunday. The 26th-seeded Hurkacz, who had eliminated four higher-ranked players en route to the final, held his nerve at Miami`s Hard Rock Stadium to win 7-6 (7/4), 6-4 in 1hr 43min. It was a deserved victory for the 24-year-old from Wroclaw, who claimed his second title of the season as Sinner`s challenge unravelled with a series of unforced errors. 

"It feels unreal, so happy that I was able to play a good match today," Hurkacz said. "Jannik is an amazing competitor. I`m so proud of myself that I was able to beat him." Hurkacz, whose win earned him a message of congratulations Polish President Andrzej Duda, said he hoped the tournament win would be a launchpad for more victories. "It gives me extra motivation and extra belief in myself, that I`ve won a really big title," he said. "It motivates me to be a better player so I can win even more." Sinner meanwhile expressed disappointment that he had been unable to take full advantage of the absence in Miami of the men`s "Big Three" -- Novak Djokovic, Rafael Nadal and Roger Federer -- by crowning a successful tournament with victory in the final.
