Kevin Anderson of South Africa defeated last year's finalist Andreas Haider-Maurer of Austria 6-4, 6-4 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 had 10 aces and broke the American's serve four times. Simon, Dolgopolov upset In St. Petersburg, top-seeded Gilles Simon and third-seeded Alexandr Dolgopolov made early exits in the first round of the St. Petersburg Open Monday. Adrian Mannarino rallied to beat his fellow Frenchman Simon 2-6, 6-4, 6-4, while Dolgopolov was upset by Israeli wild card Dudi Sela 6-2, 6-2. Earlier, fifth-seeded Mikhail Youzhny of Russia advanced to the second round, beating Sergiy Stakhovsky of Ukraine 6-3, 7-6 (7), while Potito Starace of Italy defeated Russian wild card Ivan Nedelko 6-0, 6-1. The 12th-ranked Simon, who was making his debut at the event, trailed by a break in each set. He then broke Mannarino two times in the first set and leveled at 1-all in the second. The 86th-ranked Mannarino, who is yet to win a title, broke in the ninth game to stay in the match and held his serve in the decider to close the match on his third match point. The 97th-ranked Sela broke Dolgopolov twice in each set to hand the 16th-ranked Ukrainian his second successive early exit after Jeremy Chardy of France ousted him in straight sets in Moscow last week.
