MELBOURNE, Australia (AP) The latest from the Australian Open on Saturday (all times local):
12:35 p.m.
Third-seeded Garbine Muguruza has become the latest casualty in the women's draw at Melbourne Park, beaten by Barbora Strycova 6-3, 6-2 in the day's first match on Rod Laver Arena.
Muguruza misfired frequently on her groundstrokes, finishing with 32 unforced errors, and looked a bit listless throughout the match.
Since reaching last year's Wimbledon final, the Spanish player has lost in the second round of the U.S. Open and now the third round at Melbourne Park.
Strycova has only been past the third round once before in 38 Grand Slam appearances when she reached the quarterfinals of Wimbledon in 2014.
No. 2 Simona Halep, No. 6 Petra Kvitova and No. 8 Venus Williams have also been eliminated from the tournament.

12:25 p.m.
Johanna Konta has become the first British woman to reach the fourth round at the Australian Open in 29 years.
Konta beat No. 8 Venus Williams in straight sets in the first round and on Saturday had another straight-sets win over Denisa Allertova, 6-2, 6-2.
The 47th-ranked Konta is making her debut in the main draw at Melbourne Park but has shown few jitters and a fighting spirit as she moves through the draw.
Konta said she knew what to expect from Allertova, who stretched her to three sets in the first round at last year's French Open.
The 22-year-old Konta was born in Australia and became a British citizen in 2012, making her the first British woman to reach the round of 16 at Melbourne Park since Jo Durie in 1987.
