MELBOURNE, Australia (AP) - The Latest on Friday at the Australian Open (all times local):
12:15 a.m.
After saving two match points and trailing 5-1 in the third set in her last match, there were no real dramas in the third round for Caroline Wozniacki.
The second-seeded Wozniacki beat Kiki Bertens 6-4, 6-3 to advance to a fourth-round match against Magdalena Rybarikova.
Wozniacki had to save four break points while serving for the match on Friday but clinched it on her fourth match point when Bertens’ return of serve went long.
On Wednesday, Wozniacki won the last six games of her match with Jana Fett in the second round.
The former No. 1 Wozniacki is one of four players here who could overtake top-seeded Simona Halep for the No 1. ranking at the end of the Australian Open.

French Open champion Jelena Ostapenko is out of the Australian Open, beaten 6-3, 1-6, 6-3 by Anett Kontaveit in the third round at Melbourne Park.

In the third set, Kontaveit broke Ostapenko’s service in the seventh game, held and then broke again in the ninth to end the match.

Cilic had 53 winners in the match, including 16 aces, and won 26 of 29 points at net.
Cilic next faces 10th-seeded Pablo Carreno Busta for a spot in the quarterfinals.

Nick Kyrgios won the last five points of the tiebreaker to beat 2008 finalist Jo-Wilfried Tsonga 7-6 (5), 4-6, 7-6 (6), 7-6 (5) and remain with a chance of providing a first Australian male singles winner of the Australian Open in 42 years.
Trailing 5-2 in the tiebreaker, Kyrgios went on a roll as Tsonga appeared to struggle with a knee issue.
Kyrgios is the last of nine Australian male players left in the singles draw. Mark Edmondson was the last Australian to win his national championship in 1976, although Lleyton Hewitt came close, losing the 2005 final to Marat Safin.
The 17th-seeded Kyrgios will play third-seeded Grigor Dimitrov in the fourth round. Dimitrov beat Andrey Rublev in four sets earlier Friday.

Ivo Karlovic may have lost his third-round match at the Australian Open against Andreas Seppi, but he’s still accomplishing new feats - at nearly 39 years old.
The big-serving 2.11 meter (6-foot-11) Croatian player smacked 50 aces in back-to-back matches for the first time in his career, hitting 53 in his five-set, second-round win over Yuichi Sugita and another 52 in Friday’s five-set loss to Seppi.
Karlovic fell just short of becoming the oldest player to reach the fourth round of a Grand Slam since Jimmy Connors’ run to the U.S. Open semifinals in 1991.
How does he keep doing it? Karlovic says it’s simple: He hits the gym, lifts weights and runs.
“I always say that it’s about the fitness level,” he says. “I don’t feel any weaker than when I was 28.”
Karlovic’s ranking has slid from No. 21 to No. 89 in the past year, but if he can keep it high enough to continue playing in ATP-level events, he could see himself sticking around for several more years.
“I think I can still do upsets here and there, so I like it still,” he said.

Top-seeded Rafael Nadal is through to the fourth round at Melbourne Park, beating Damir Dzumhur 6-1, 6-3, 6-1 in a night match at Margaret Court Arena.

Will Smith made his Grand Slam debut on Friday night, taking a seat at Rod Laver Arena for a third-round Australian Open match between local hope Nick Kyrgios and 2008 finalist Jo-Wilfried Tsonga.
The actor briefly met Tsonga before the players walked onto the court.
“Really a great guy. Really sweet. Love his energy,” Smith told former player Jim Courier in an interview aired on the Seven Network. “Happy being here watching these guys play.”
Smith has spent 10 days in Australia taking a break before starting work on a movie.
“This is the first time at the Open - this is my first Slam,” said Smith, who planned to watch top-ranked Rafael Nadal on nearby Margaret Court Arena but decided to stick around on the main show court.

The 33-year-old Seppi clinched the match with a break of the 38-year-old Karlovic’s service, only his second break of nine attempts during the match. Seppi saved both break points against him.
Seppi plays Kyle Edmund of Britain in the fourth round. Edmund also had a five-set win Friday, beating Nikoloz Basilashvili in 3 hours, 34 minutes.

Dimitrov will next play the winner of Friday night’s match on Rod Laver between local hope Nick Kyrgios and 2008 finalist Jo-Wilfried Tsonga in the round of 16.

Melbourne Park was expected to be scorching on Friday, with temperatures reaching 42 Celsius (108 Fahrenheit) for the fifth day of the Australian Open.
While top-seeded Rafael Nadal, Nick Kyrgios and Caroline Wozniacki were among those scheduled to play their third-round matches, tournament officials were expected to keep a close eye on the rising temperatures. When play began at 11 a.m., it was already 35 C (95 F).

When both those temperatures are exceeded, matches on outside courts are supposed to be suspended and the roofs closed on all three main stadiums - Rod Laver Arena, Margaret Court Arena and Hisense Arena.
