Indian Wells - World number four Andy Murray has sailed into the quarter-finals of the BNP Paribas Open on Wednesday while fifth-ranked Kei Nishikori crashed out of his last-16 test at Indian Wells.
The Scotsman posted a routine 6-3 6-3 win over Frenchman Adrian Mannarino, but Japan's Nishikori failed to keep their expected clash in the last eight by losing 6-4 7-6 (2) to 12th-seeded Spanish veteran Feliciano Lopez.
Nishikori, last year's U.S. Open runner-up, failed to cash in on six of his seven break points as he fell to the hard-serving Lopez, who registered 12 aces.
Murray kept the pressure on Mannarino throughout the 90-minutes match, reaching break point 11 times and breaking serve four times for a comfortable victory.
