The latest from the Australian Open on Tuesday (all times local):
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."
