The triumph in chilly suburban Phoenix sends the United States into a semifinal matchup against the Czech Republic.
Teenager Melanie Oudin rallied to beat Jozami in the day’s second singles match to send the competition to the deciding doubles.
Oudin, a fiesty 17-year-old from Marietta, Ga., defeated Jozami 2-6, 6-1, 6-2. Argentina took a 2-1 lead in day’s first match when Dulko defeated Jill Craybas 6-1, 6-3 in a meeting of the top two players in the competition.
