Karen Khachanov and Andrey Rublev helped Russia open the inaugural Davis Cup Finals with a 3-0 victory over defending champion Croatia in Madrid on Monday.
World No. 17 Khachanov clinched the point for Russia by fighting back to beat Croatian No.1 Borna Coric 6-7(4), 6-4, 6-4, after Rublev had earlier seen off Borna Gojo 6-3, 6-3.
Khachanov and Rublev completed a clean sweep with a 7-6(3), 6-4 doubles win over Ivan Dodig and Nikola Mektic.
Canada claimed a 2-1 victory over well-fancied Italy to strike first in Group F. World No. 12 Fabio Fognini slumped to a 7-6(5), 7-5 defeat by Vasek Pospisil, ranked 150th, before rising star Denis Shapovalov edged out Matteo Berrettini 7-6(5), 6-7(3), 7-6(5).
The 20-year-old Shapovalov saved three set points before snatching the first set in a tie-break, only for Berrettini to level the match in a second-set breaker.
A clash without a single break of serve, was decided by another tie-break, with Shapovalov reeling off the last three points to win after two hours and 52 minutes on court.
Berrettini and Fognini boosted Italy’s hopes of making the quarters with a hard-fought doubles success over Shapovalov and Pospisil.
