Last week, Nagal failed to reach the final of ATP Challenger Campinas in Brazil as he lost in straight sets to Argentina's 325-ranked Juan Ficovich. He did not look in his elements right from the start as he lost the match 4-6, 1-6 which eventually turned out to be a one-sided contest on Saturday.
Before that, the 22-year-old had achieved his career-best ranking of 135 after clinching the men's singles title at the Buenos Aires ATP Challenger clay event. Nagal had made a jump of 26 places after he clinched his second Challenger title in Argentina.
The Haryana lad had grabbed headlines after he made his Grand Slam debut in August and produced a spirited fight against Swiss maestro Roger Federer in the first-round of the US Open.
