Tommy Paul beats Dino Prizmic in four sets at US Open

Tommy Paul needed four sets to see off Dino Prizmic 6-2 6-3 5-7 6-4 in the US Open second round, controlling the opening two sets before a brief stumble in the third. The American's first delivery was the difference: he landed only 54.1% of first serves but won 83.1% of those points, and struck nine aces to Prizmic's two. The Croatian's second serve was the weak link, yielding just 37.0% of points won and eight double faults against Paul's four. Having steadied himself after losing the third, Paul moved into the next round with his level intact.
