Juan Monaco gains semifinals
"I was good tactically and did not give him a chance to come back into the game," Benneteau said.
Nishikori, Asia's top-ranked player, advanced when 2009 champion Nikolay Davydenko retired after losing the first set of their quarterfinal 6-4. Davydenko also pulled out of the quarterfinals here last year with an injury.
"It's sad to see him retire, but hopefully he is fine," Nishikori said.
