Kevin Anderson defeated 2010 finalist Andreas Haider-Maurer of Austria 6-4, 6-4 Monday in the opening round of the Erste Bank Open.
The sixth-seeded South African relied on his serve, breaking Haider-Maurer once in each set. He closed out the win with his 10th ace.
Anderson won his first career title in Johannesburg this season. He 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.
