After struggling at times during his maiden match at the 2018 Miami Open, Denis Shapovalov responded with a straight-sets victory in the round of 64 against Damir Dzumhur on Saturday.
The 18-year-old took 72 minutes to earn the 6-1, 7-5 result, downing the world No. 30 in style.
Shapovalov cruised through the first set, serving up six aces and winning 100 percent of his first-serve points along the way. The teenager also managed to convert a pair of break points as Dzumhur had no answer for his younger opponent in the early going.
The Bosnian would provide much more of a challenge in the second set, with Shapovalov looking to end the match early. Dzumhur began to figure out the Canadian's service game, leading to a good back-and-forth set as the players battled for superiority.
A+ tennis between @dzumhurdamir and @denis_shapo!
