Italian Jannik Sinner continued to overachieve, with the teenager spending 70 minutes in reaching the first Masters 1000 quarter-final of his career on Tuesday with a 6-3, 6-2 defeat of Emil Ruusuvuori.
Sinner, 19, bounced back without problems after a three-hour win in the previous round as he defeated the first Finn to play the Florida fourth round since Jarkko Nieminen in 2007.
Sinner is competing in only his third career tournament at the Masters level; he lost his only other contest against the 21-year-old Ruusuvuovi 14 months ago at the Canberra Challenger in Australia.
“He’s obviously a very great player, beating very great tough opponents here. I was ready for this today and I’m very happy. .
“This means a lot,”the No. 31 winner said. “The first goal is always trying to improve day after day.
“When you have sometimes good results, it makes you happy. I’m obviously looking forward to tough matches here.”
No. 83 Ruusuvuori, a semi-finalist last autumn in Kazakhstan, was unable to convert on any of his four break point chances.
Sinner’s quarter-final opponent will be Alexander Bublik who beat Taylor Fritz 6-7,6-3,6-4
.“You have to go on court and try to win matches. I’m just trying to do that,” Sinner said. “Sometimes it works, sometimes not.
“For me, it’s just important to give 100 percent day after day and then I have to see what’s going to happen.”
A break of serve by Ruusuvuori to start the match was quickly nullified by Sinner, who went on to take control all the way to victory.
