Argentina serves up Davis Cup surprise

Argentina lifted its first Davis Cup title after Juan Martin Del Potro and Federico Delbonis won Sunday's reverse singles to complete the South American nation's spectacular comeback in a 3-2 victory over host Croatia in the final.

Del Potro fought back from two sets down to beat Marin Cilic 6-7 (4), 2-6, 7-5, 6-4, 6-3 before Delbonis swept aside Ivo Karlovic 6-3, 6-4, 6-2 in the decisive rubber, sparking wild celebrations among several thousand Argentine fans in the Zagreb Arena.

Argentina joined the list of Davis Cup winners after losing all four finals it had previously contested, and its dismal record in the title showdown appeared set to continue when Cilic came within a set of clinching Croatia's second championship.
