Teenager Tien Continues Rise After Defeating Monfils at US Open

Twenty‑year‑old Tiago Tien, who upset Monfils in New York, is enjoying a breakthrough season. After a win over the French star, Tien also defeated Monfils in Montreal the previous month and asked for an autograph from his childhood idol. The Canadian’s campaign this year includes a quarterfinal appearance at the Australian Open, a semifinal run at the ATP Masters 1000 in Canada, and a third‑round berth at the US Open, where he will face Jacob Mencik next.
