Borna Coric kept his cool to prevail in a thrilling winner-takes-all clash with fellow young gun Frances Tiafoe and Steer Croatia into the final of the Davis Cup for the second time in three years with a monumental 3-2 victory over the U.S in Zadar.

The 21-year-old Coric came from two sets to one down to defeat 20-year-old debutant Tiafoe 6-7, 6-1, 6-7, 6-1, 6-3, and finally subdue a remarkable Fightback from the Americans, who had earlier leveled the tie 2-2 from two down.

Coric demonstrated why he is seen as one of the sport’s best prospects, holding his nerve against the brilliant young American and proving to be too solid over the final two sets as he finally prevailed after four hours six minutes.

For USA – without their top two players John Isner and jack sock – the dream of reaching a first final in 11 years slips by.
