Carlos Alcaraz made a stunning start to his Davis Cup career on Friday, helping six-time champions Spain to a comfortable 2-0 lead over Romania on the first day of their qualifying tie. The 18-year-old Alcaraz, ranked 19 in the world, swept past the experienced Marius Copil 6-4, 6-3 on the clay courts of Marbella. "I was nervous, but no more than usual. Having an experience like this in the Davis Cup helps you grow as a player and as a person," said Alcaraz widely seen as his country's tennis heir apparent to Rafael Nadal who has skipped this tie.
