Teenager Borna Coric seals Croatia's victory in Davis Cup

LIEGE, Belgium (AP) - Teenager Borna Coric defeated Kimmer Coppejans of Belgium in straight sets, 7-6 (5), 6-2, 6-2, in the decisive singles match to book a spot for Croatia in the quarterfinals of the Davis Cup on Sunday.

The 19-year-old Coric hit seven aces and converted four of five break chances against Coppejans, ranked 122nd in the world.

Croatia, which qualified for the cup quarterfinals for the first time in four years, will take on the United States in July.

Coric sealed the match with an ace.

Belgium's David Goffin earlier defeated Marin Cilic 6-4, 6-4, 3-6, 7-5 to level the first round tie at 2-2. Despite his 14 aces, Cilic was broken five times on the clay court of the Country Hall.

Cilic, the 2014 U.S. Open champion, saved a match point at 5-6, 15-40 but hit a double fault on his next serve.

Belgium reached its first final in 111 years last year before losing to Britain.
