Thiem, Tsonga have 2-set wins to advance in Vienna

Vienna - Jo-Wilfried Tsonga had 11 aces and avoided break points

Third-seeded Dominic Thiem defeated fellow Austrian Gerald Melzer 6-0, 6-3 in the first round of the Erste Bank Open on Tuesday.
 Thiem, who had not won a match in his home events since reaching the quarterfinals in 2013, conceded just eight points in a 20-minute opening set, and broke Melzer for a fourth time at 4-4 in the second set.
 Thiem next plays Viktor Troicki of Serbia, who converted his only break point in the final set to complete a 4-6, 7-6 (5), 7-5 comeback win over Kevin Anderson of South Africa.
 Also, 2011 champion Jo-Wilfried Tsonga had 11 aces and avoided break points while beating German qualifier Benjamin Becker 6-3, 6-4.
 Earlier, defending champion David Ferrer had to play only five games to advance to the second round after Kyle Edmund pulled out with a hip injury.
 The fifth-seeded Spaniard was a service break up at 3-2 when his British opponent, who is ranked a career-high 40th, quit the match. Edmund had beaten Ferrer on the way to his first-career semifinal appearance in Antwerp last week.
 Ferrer next plays Joao Sousa of Portugal, who led Pablo Cuevas 6-3, 3-0 when the Uruguayan pulled out.
 Also, Feliciano Lopez, who won his maiden title in Vienna in 2004, defeated seventh-seeded Lucas Pouille 6-4, 2-6, 7-5 to set up a match against John Isner of the United States.
