0404 NADAL TOO GOOD FOR DUCKWORTH
World number two Rafa Nadal swatted aside Australian wild card James Duckworth 6-4 6-3 7-5 in a performance that eased concerns over his fitness ahead of the season's first major.
The 2009 winner had pulled out of the Brisbane International warmup with a thigh strain but showed no signs of the problem in his opener, beating Duckworth in two hours and 15 minutes.
He faces Matthew Ebden or Jan-Lennard Struff next.

0332 ANDERSON EASES PAST MANNARINO
Wimbledon runner-up Kevin Anderson fired 14 aces and 47 winners to blast past Frenchman Adrian Mannarino 6-3 5-7 6-2 6-1 and move into the second round.
The towering South African, who has never gone beyond the fourth round in Melbourne, next meets unseeded American Frances Tiafoe, who beat qualifier Prajnesh Gunneswaran 7-6(7) 6-3 6-3.
0245 BOULTER FIRST TO WIN DECIDING TIE-BREAK
Britain's Katie Boulter became the first player to win a deciding-set tiebreak at the Australian Open when she managed to hold off a resurgent Ekaterina Makarova and record a 6-0 4-6 7-6 (10-6) victory.
Boulter, who had also recorded the first 'bagel' of the tournament when she took the first set of their clash on Court 12, then struggled to put away the Russian.
Makarova, a former top-10 player, managed to clinch the second set 6-4 before Boulter overcame a break advantage in the third to force the tiebreak.
She then jumped out to a 5-0 lead in the first to 10 points and while Makarova got back to 7-6, Boulter sealed the match with an ace and forehand winner.
The Australian Open has joined Wimbledon this year in introducing a tiebreak when matches are tied at 6-6 in the deciding set. The first player to 10 points with a difference of two wins the contest.
0237 AMERICAN COLLINS UPSETS 14TH SEED GOERGES
Germany's Julia Goerges became the first seeded player knocked out of the tournament when American Danielle Collins came from a set down to record a 2-6 7-6(5) 6-4 victory in the first match on Margaret Court Arena.
The 14th-seeded Goerges had come into the tournament in strong form having successfully defended her Auckland Classic title but looked uncomfortable against the power-hitting 25-year-old, who went for her shots during the second set.
The tactic paid off for Collins, who sealed the win in two hours, 25 minutes when her winner smacked into the net and the ball flopped into Goerges' side of the court.
"The first set didn't go my way but I had a clear mindset about what I needed to do," said Collins, who was making her main draw debut at Melbourne Park.
"I decided today that I had to earn it the hard way, no easy jobs for me and I just out went there with no fear."
0225 VERDASCO FIRST MAN THROUGH TO SECOND ROUND
Spain's former top-10 player Fernando Verdasco became the first man through to the second round after he beat Serbian qualifier Miomir Kecmanovic.
The left-handed 26th seeded Verdasco took two hours, 11 minutes to beat the teenager 7-6(5) 6-3 6-3 and set up a second round clash against Moldova's Radu Albot.
0118 SHARAPOVA 'DOUBLE BAGELS' DART
Former champion Maria Sharapova opened the quest for her second title at Melbourne Park with a 6-0 6-0 victory over British qualifier Harriet Dart.
The 22-year-old Briton saved two match points but blasted a backhand volley wide to give the Russian a rare 'double bagel' victory in 63 minutes.
0114 MARTIC FIRST INTO SECOND ROUND
Croatia's Petra Martic wasted little time in the rising temperature to become the first player through to the second round after she demolished Britain's Heather Watson 6-1 6-2 on Court 14.
The 31st seed took just 62 minutes to beat Watson and will now meet Czech Republic's Marketa Vandrousova, who beat Russia's Evgeniya Rodina 6-3 6-2 within minutes of Martic's victory.
0015 PLAY UNDERWAY AT MELBOURNE PARK
Play got underway on schedule under sunny skies at 11 a.m. local time (0000) GMT with the temperature hovering just over the 25 degrees Celsius mark with a forecast high of 35C. (Compiled by Greg Stutchbury and Shrivathsa Sridhar, editing by Nick Mulvenney)
