On Sunday in the Davis Cup final, Argentina's Federico Delbonis became a hero by beating Ivo Karlovic 6-3, 6-4, 6-2 in the deciding fifth rubber against Croatia.

Earlier in the day, Juan Martin del Potro pulled off some heroics of his own, coming back from two sets down to beat Marin Cilic, 6-7 (4), 2-6, 7-5, 6-4, 6-3.

The 28-year-old Del Potro had never previously come back from a two-set deficit to win a match.

It was Argentina's first-ever Davis Cup title win, and the fans, and players, were more than a little thrilled.

Croatia was seeking its second Davis Cup title in history, while Argentina was playing in its fifth final.
