Vienna: Kevin Anderson of South Africa defeated last year's finalist Andreas Haider-Maurer of Austria 6-4, 6-4 on Monday in the opening round of the Erste Bank Open.

The sixth-seeded Anderson, who won his maiden career title in Johannesburg this season, relied on his serve and broke Haider-Maurer once in each set. He closed out the win with his 10th ace.

Anderson will next play Marcos Baghdatis of Cyprus, who defeated the 73rd-ranked Ryan Sweeting 6-4, 6-2.

Baghdatis, who reached the final in Kuala Lumpur this month, had 10 aces and broke the American's serve four times.
