International

Argentina completed an improbable comeback to claim its first Davis Cup title, storming back from the brink of elimination to defeat Croatia on Sunday.

The South American nation was one set from defeat in the fourth rubber, with Marin Cilic leading Juan Martin del Potro two sets to love, and they would mount a historic rally to lift the trophy. Del Potro turned in his first career two-set comeback 6-7(4), 2-6, 7-5, 6-4, 6-3, followed by a clutch 6-3, 6-4, 6-2 win for Federico Delbonis over Ivo Karlovic.
