Victoria Azarenka, Bianca Andreescu advance to second round at Guadalajara Open

Twice major winner Victoria Azarenka downed Russian Elina Avanesyan 6-4 6-2 and former U.S. Open champion Bianca Andreescu cruised past Swiss Jil Teichmann 6-2 6-4 in the first round of the Guadalajara Open on Monday.

Six of the world's top 10 are expected to play in the hard-court tournament, the final WTA 1000-level event this season before the WTA Finals, with Polish world number one and U.S. Open winner Iga Swiatek absent after winning in San Diego on Sunday.

Azarenka, who reached the last 16 in New York but lost in her Ostrava opener earlier this month, dropped only three first-serve points in the first set and broke in the seventh game.

The Belarusian's serve deteriorated in a choppy second set but her 20-year-old opponent could not derail the experienced Azarenk, who set up a second-round meeting with Spanish top seed Paula Badosa in a repeat of the Indian Wells final last year.

Canadian Andreescu had no problem overcoming Teichmann, winning the first three games of the first set and cruising through the second as the Swiss served three double faults.

Andreescu's win sets up a first career meeting with Petra Kvitova after the Czech put on a serving masterclass and crushed six aces to overpower Bernarda Pera 6-3 7-5.

Russian Liudmila Samsonova, who won in Cleveland and Tokyo this year but lost her first-round match in San Diego, beat Estonian Kaia Kanepi 6-1 7-5 and China's Zhu Lin defeated Frenchwoman Alize Cornet 3-6 6-3 6-4.

The biggest upset of the day belonged to 20-year-old Colombian Camila Osorio, who broke 15th seed Ekaterina Alexandrova nine times en route to a 6-4 7-6(8) victory.

American Sloane Stephens, Belgian Elise Mertens, Ukrainian Marta Kostyuk and Canadian Rebecca Marino all advanced to the second round after straight sets wins.
