MELBOURNE, Australia (AP) The latest from the Australian Open on Thursday (all times local):
2:38 p.m.
Victoria Azarenka has quickly dispatched another opponent at Melbourne Park, defeating Danka Kovinic of Montenegro 6-1, 6-2 in just over an hour.
The two-time Australian Open champion hasn't given up more than three games in any of the 14 sets she has played this year, including her run to the title at the Brisbane International two weeks ago.
She beat Alison Van Uytvanck 6-0, 6-0 in the first round at Melbourne Park.
''I really don't count the games,'' she said after Thursday's match. ''What really works for me is to stay in the moment. It keeps me focused.''
Azarenka next plays Japan's Naomi Osaka, who has reached the third round of a Grand Slam for the first time with a win over the 18th seed, Elina Svitolina.

Third-seeded Garbine Muguruza had a 6-4, 6-2 win over Kirsten Flipkens to reach the third round of the Australian Open for the third straight year.
Muguruza, who lost last year's Wimbledon final to Serena Williams, made it to the fourth round in 2014 and 2015 at Melbourne Park. Last year, Williams beat the Venezuelan-born Spaniard in the fourth round here.
Muguruza will next play Barbora Strycova, who beat American Vania King 7-6 (5), 6-4.

John Isner is back in the third round at Melbourne Park for the fifth time in seven years following a 6-3, 7-6 (5), 7-6 (2) win over Marcel Granollers of Spain.
The 10th-seeded Isner had 20 aces and 53 winners in the match, and also won 33 of his 44 approaches to net.
He was one of eight Americans through to the second round at the Australian Open - the most since 2008. Four other Americans are playing their second-round matches on Thursday.
Isner has only been past the third round once before in Melbourne. He faces the winner of the match between Spain's Feliciano Lopez and Guido Pella of Argentina.
Isner lost to Lopez in the third round in 2012.

Ana Ivanovic has advanced to the third round at Melbourne Park following a 6-3, 6-3 win over qualifier Anastasija Sevastova in a match that was suspended when a spectator fell on the stairs at Rod Laver Arena.
