Top-seeded David Ferrer of Spain rallied past Igor Sijsling of the Netherlands 4-6, 6-3, 6-4 Friday to advance to the semifinals of the Malaysian Open.
He'll face Julien Benneteau of France, who defeated Alejandro Falla 6-2, 6-2 at Kuala Lumpur's Putra Stadium.
''I was good tactically and did not give him a chance to come back into the game,'' Benneteau said.
Second-seeded Juan Monaco of Argentina beat Vasek Pospisil of Canada 6-3, 6-4 to set up a semifinal against Kei Nishikori of Japan.
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.
