Top seed Janko Tipsarevic moved in the quarterfinals at the Thailand Open tennis event.

The world No. 9 Serbian star posted a 6-4, 6-4 second-round victory against Japanese qualifier Hiroki Moriya on Wednesday on the hardcourts at Impact Arena.

Tipsarevic was joined in the quarterfinals by seventh-seeded Finn and 2010 Bangkok runner-up Jarkko Nieminen, who got past German Philipp Petzschner 7-6 (7-1), 6-2 in Day 3's nightcap.

In some first-round action, former top-10 Frenchman Gael Monfils topped South African qualifier Kevin Anderson 6-4, 2-6, 7-5, Japan's Go Soeda defeated wild card and Thailand's own Danai Udomchoke 6-4, 7-5 and 6-foot-10 Croat Ivo Karlovic bested Aussie Marinko Matosevic 6-3, 6-4.

In some more second-round play on Thursday, second-seeded Frenchman Richard Gasquet will take on promising Bulgarian Grigor Dimitrov, third-seeded Canadian slugger Milos Raonic will battle the towering Karlovic and fourth- seeded Frenchman Gilles Simon will be opposed by Soeda. Simon captured this event in 2009.

The 2012 winner of this $551,000 tournament will collect $99,465.
