MELBOURNE, Australia | The Latest: Kerber stunned by Collins of US in Melbourne

MELBOURNE, Australia— January 19, 2019—The Latest on Sunday from the Australian Open (all times local):

4:15 p.m.

Three-time major champion Angelique Kerber was stunned 6-0, 6-2 by Danielle Collins of the U.S. in just 56 minutes in the Australian Open’s fourth round.

Collins had an 0-5 career record in Grand Slam tournaments until this one. But she has now added an upset of No. 2 Kerber to earlier victories over a pair of seeded women, No. 14 Julia Goerges and No.

19 Caroline Garcia.

Collins was the more aggressive player throughout and finished with a resounding 29-6 edge in total winners.

The former University of Virginia player will face 2017 U.S. Open champion Sloane Stephens or Anastasia Pavlyuchenkova next.


3 p.m.

Ash Barty beat Maria Sharapova 4-6, 6-1, 6-4 to reach her first Grand Slam quarterfinal and gave Australian its first woman that deep in its major tournament since 2009.

Barty opened the deciding set by breaking Sharapova’s serve, helped by two of Sharapova 10 double-faults in the match. It came minutes after the capacity crowd lustily booed Sharapova when she returned from an extraordinary long toilet break after the second set.

Barty broke 2008 champion Sharapova’s serve again to lead 3-0, helped by two unforced errors by the Russian and went up 4-0 while holding serve with four straight points. Sharapova faced more break points in the next game but held serve, ending a winning streak of nine consecutive games by Barty.

Sharapova, who beat defending champion Caroline Wozniacki in the third round, broke Barty’s serve in the next game and then closed to 4-3 in a game which included the point of the tournament — a 21-shot rally that included great gets by both players and ended with a wide backhand by Barty.

Barty was forced to save two break points in the next game, but held to go up 5-3. After Sharapova held in the next game, she saved one match point before Barty ended the 2-hour 22-minute match with an ace.

The Australian will next play two-time Wimbledon champion Petra Kvitova, who beat 17-year-old American Amanda Anisimova in straight sets.


12:15 p.m.

Two-time Wimbledon champion Petra Kvitova is the first player into the Australian Open quarterfinals after beating 17-year-old American Amanda Anisimova 6-2, 6-1 to open play Sunday at Rod Laver Arena.

Kvitova, who had a WTA Tour-leading five tournament wins last year, extended her winning streak to nine matches after capturing the Sydney International title last week and her four wins at Melbourne Park this week. She hasn’t made the quarterfinals here since 2012.

Anisimova, one of three American women playing fourth-round matches Sunday, beat seeded players in the second and third rounds.

She was the youngest player to reach the Round of 16 here since 2006 and the youngest in any Grand Slam tournament since 2007.


11 a.m.

Two-time Wimbledon champion Petra Kvitova opens play at Rod Laver Arena on Day 7 of the Australian Open with a match against 17-year-old American Amanda Anisimova.

Anisimova has beaten two seeded players on her way to the fourth round and a win Sunday would advance her to a quarterfinal against either Ashleigh Barty or Maria Sharapova, who meet in the following match at Rod Laver.

Rafael Nadal is to play his Round of 16 match against Tomas Berdych. Six-time champion Roger Federer, playing in his 20th Australian Open, takes on 20-year-old Stefanos Tsitsipas to open night play.

The weather is mostly sunny with an expected high temperature of 24 Celsius (75 Fahrenheit).
