MELBOURNE, Australia (AP) - The Latest on Monday at the Australian Open (all times local):
4:35 p.m.
Milos Raonic has beaten racket-smashing No. 4-seeded Alexander Zverev 6-1, 6-1, 7-6 (5) on his fourth match point to reach the Australian Open quarterfinals for the fourth time.
The big-serving Canadian had his serve broken in the opening game but responded by winning the next eight games to go up a break in the second set. After falling behind 4-1 in the second, Zverev had just about enough.
The 21-year-old German sat down in his courtside chair and destroyed his racket by whacking it against the ground eight times - and then tossing it aside.
He was warned for racket abuse after the display and, after dropping the set two games later, he left the court and went to the locker room.
When he returned, he only dropped one point on his serve until the eighth game, but suddenly things went haywire again when he faced two match points. Zverev composed himself to save those two break points and led in the tiebreaker until Raonic went on a roll.
From 3-1 down, Raonic rallied to get to 6-4 and missed one more match point before finally converting.
The 2016 Wimbledon runner-up will face either No. 11 Borna Coric or No. 28 Lucas Pouille in the quarterfinals.

U.S. Open champion Naomi Osaka is into her second Grand Slam quarterfinal after another comeback win at the Australian Open, this time over Anastasija Sevastova.
Osaka had to work for nearly two hours on Rod Laver Arena to subdue the gritty Sevastova 4-6, 6-3, 6-4 in a fourth-round match studded by service breaks. She'll next play sixth-seeded Elina Svitolina, who had a 6-2, 1-6, 6-1 win over 2017 U.S. Open finalist Madison Keys.
Osaka won a tight three-setter when she met Sevastova at the Brisbane International in the first week of the season.
Sevastova grabbed the lead in the opening set on Monday, and clinched it with a deft drop shot that forced Osaka to fly a forehand over the baseline.
Osaka had to stave off two break points in the third game of the second to edge ahead.
The fourth-seeded Osaka grew in confidence from the narrow escape and lifted her tempo and shot-making consistency, grabbing the crucial service break in the sixth game.
Serving to level the match, Osaka fended off a break-back point with a brilliant forehand volley after a long, tense baseline rally. Two points later, the match was heading into the deciding set.
Osaka broke serve to open third set to maintain the momentum.

Sixth-seeded Elina Svitolina has advanced to the Australian Open quarterfinals with a momentum-swinging 6-2, 1-6, 6-1 win over 2017 U.S. Open finalist Madison Keys.
The WTA Finals winner fended off five breakpoints in a pivotal third game in the third set that went to deuce 11 times and lasted more than 15 minutes. She broke Keys' serve at the first opportunity in the next game and finished off the match quickly.
It ended a comeback by Keys, who didn't quite find her range with her ground strokes and 34 unforced errors, including some very nears misses on big points.
Both players reached the quarterfinals here last year, but Keys had more success at the majors in 2018 when she progressed to the semifinals at the French and U.S. Opens.
"I was happy I could handle the pressure at 1-1 in the third set," Svitolina said. "It was very hard because the sun was just burning my eyes when I was tossing the ball. Very happy I could win that game."
Svitolina will next play either U.S. Open champion Naomi Osaka or No. 13 Anastasija Sevastova.

The winner will advance to quarterfinal match against either U.S. Open champion Naomi Osaka or No. 13 Anastasija Sevastova.
In the night matches later Monday, Serena Williams continues her bid for an eighth Australian and Open-era record 24th singles major when she takes on No. 1-ranked Simona Halep, and six-time men's winner Novak Djokovic is against Daniil Medvedev.
