The Latest: VWilliams out in 1st round at Australian Open
MELBOURNE, Australia (AP) The latest from the Australian Open on Tuesday (all times local):
Venus Williams has been knocked out of the first round 6-4, 6-2 by Britain's Johanna Konta. The eighth-seeded Williams reached the quarterfinals at Melbourne Park last year to kick off a resurgent season that saw her return to the top 10 for the first time since 2011.
Against Konta, however, she struggled to connect with her first serve and couldn't match the Australian-born Konta's power from the baseline. She had just one ace compared to five for the Briton.
''When the draw came out and I saw who I was playing, I thought `I just hope I stay out there more than an hour,''' Konta said after the match.
Konta was making her Australian Open debut, but has played well in the past against top-10 opponents. She beat No. 9 Garbine Muguruza on the way to the fourth round of the U.S. Open last year and also had a win over No. 2 Simona Halep.
Madison Keys had a slow start in her return to Melbourne Park, but advanced to the second round with a 7-6 (5), 6-1 win over Zarina Diyas.
Keys, who reached her first Grand Slam semifinal last year at the Australian Open, fended off two set points in the ninth game before coming back to win the first in a tiebreaker. She then raced out to a 5-0 lead in the second set to put the match away.
''I think being down set point almost helped me. I thought, `You're down, keep playing. You can only lose the set,''' she said. ''I definitely had to dig deep and figure it out.''
Keys has a new coach to start the new season. Last year, she had a successful partnership with former No. 1 Lindsay Davenport, reaching the second week at three of the four Grand Slam tournaments.
But Davenport couldn't travel fulltime with Keys because of her family and commentating responsibilities, so Keys is now working with former ATP player Jesse Levine.
Milos Raonic followed up his victory at the Brisbane International with a clinical, 6-1, 6-4, 6-4 first-round win over Lucas Pouille on the second day of the season's first major.
Raonic, who at No. 13 has his lowest seeding at a Grand Slam tournament since Wimbledon 2013, is aiming to improve on his run to the quarterfinals here last year, when he lost to eventual champion Novak Djokovic.
The 25-year-old Canadian, who recently started working with former No. 1-ranked Carlos Moya as a coach, didn't face a breakpoint on his serve and had little difficulty in winning 89 percent of points on successful first serves.
He also won points on 22 of his 30 trips to the net. Pouille, a 21-year-old Frenchman, entered the match with a 1-7 record in Grand Slam matches and with a No. 90 ranking.
Wimbledon finalist Garbine Muguruza needed only an hour to advance through the first round, beating No. 85-ranked Anett Kontaveit 6-0, 6-4 in the opening match on Rod Laver Arena on day two.
The third-seeded Muguruza, who has reached the fourth round on two of her three previous trips to Melbourne Park, broke Kontaveit three times in a 23-minute first set and got an early break in the second.
The 22-year-old Spaniard retired during her first match at an Australian Open warmup tournament in Brisbane because of an injured left foot earlier this month but showed no signs of difficulty at Melbourne Park.
''Yeah, I had a few problems but, well, I think I'm recovered now,'' she said of the foot problem, ''so very good.''
