Tomas Berdych Forced to Withdraw due to illness
World No. 48 Kei Nishikori advanced to the second round, having been leading 6-2 when his Spanish opponent, Pere Riba, was forced to retire. The Japanese player is making his debut in Barcelona on the back of reaching his first ATP World Tour clay-court final in Houston (l. to Sweeting) 10 days ago.
The 21-year-old Nishikori had been due to face fifth-seeded Czech Tomas Berdych in the second round, but Berdych was forced to withdraw due to a viral gastroenteritis also called the "stomach flu" and is replaced by Portuguese lucky loser Rui Machado.
