Argentina is seeking its first-ever Davis Cup title when it faces Croatia in Zagreb. The spirited team upset defending champion Great Britain in the semifinals to earn a shot at history. Here's who they're putting forth to lead the charges:
Age: 28
Ranking: No. 38 (doubles No. 351)
Davis Cup record: 14-5
Year highlight: He won a silver medal in Rio, and his 19th title in Stockholm but the five-set epic he won over Andy Murray in the Davis Cup semifinals was his most heroic moment.
