Novak Djokovic, Serena Williams strong at Australian Open
Three-time defending men's champion slighty rusty in first match
A rusty Novak Djokovic began his bid for a fourth consecutive Australian Open title on Monday with a win over Lukas Lacko while Serena Williams looked as polished as ever beating Australian teenager Ashleigh Barty.
With his new coach and six-time Grand Slam singles champion Boris Becker watching him during an official match for the first time, Djokovic appeared tentative early against the Slovakian player, who often appeared content to keep the ball in play.
But as the second-seeded Djokovic's patience level began to drop, his skill level stepped up. He stayed on course for a fifth Australian title with a 6-5, 7-6 (2), 6-1 win, hoping to be the first man to achieve that feat since the Open Era began in 1968.
Top-ranked Williams won her 23rd consecutive match, including 18 at the end of last season and four last week in winning the Brisbane International, after beating Barty 6-2, 6-1 in 57 minutes.
"You have to be ready," Williams said. "She had nothing to lose."
Williams continues to be in rarified territory. Her Brisbane title was the 58th of her pro career. She won 11 last year, including the French Open and U.S. Open. A five-time winner of the Australian Open, she's trying to end Victoria Azarenka's two-year run as women's champion at Melbourne Park.
Williams won 10 of 11 points at the net during the Barty match, but tried to dowse expectations that she'll vacate her usual place at the baseline.
"In my mind I've been at the net [previously], but now I'm physically going there a little more," Williams said. "No pressure.
"My next match, I might stay at the baseline the whole time. It's nothing I'm permanently working on. I'm just trying to have fun and do what I want to do out there."
Djokovic also had a strong finish to 2013, entering the
tournament on a 24-match winning streak, which followed his loss to Rafael Nadal in last year's U.S. Open final. He's now also on a 22-match winning streak at Melbourne Park.
"It is the first competitive match I've had this season, I haven't played for five or six weeks," Djokovic said. "I was a bit rusty on the court the first two sets. Afterwards, it was all working well."
Serena's sister, Venus Williams, started well earlier Monday but unforced errors in two key periods in her match sent the seven-time major winner out of the tournament.
The elder Williams missed a break-point chance in the sixth game and then, after getting to 40-30 on serve in the ninth, inexplicably fired three consecutive double-faults to surrender a break and just about the set to No. 22-seeded Ekaterina Makarova.
She took a 3-0 lead in the third before her unforced error toll climbed to 56 and Makarova won six of the next seven games for a 2-6, 6-4, 6-4 win.
The 33-year-old Venus Williams, the second-oldest player in the tournament, has struggled with injuries and illness in recent seasons, but reached the final of the WTA event at Auckland to start 2014 and came to Melbourne saying she was feeling better than she had in years.
"The last 12 months I have had issues," she said. "But this year, I definitely am looking forward to having a good run and feeling well."
Kvitova, Errani, Vinci exit early
Three-highly-ranked players were beaten in the first round, including 2011 Wimbledon champion Petra Kvitova and two Italians, No. 7 Sara Errani and No. 12 Roberta Vinci.
Sixth-seeded Kvitova lost 6-2, 1-6, 6-4 to No. 88-ranked Luksika Kumkhum of Thailand, who was playing in just her second Grand Slam tournament.
Women's winners included two-time Australian Open finalist Li Na, Wimbledon semifinalist Kirsten Flipkens, No. 9 Angelique Kerber, 2011 U.S. Open champion Sam Stosur, No. 14 Ana Ivanovic, No. 26 Lucie Safarova, No. 28 Flavia Pennetta, No. 30 Eugenie Bouchard and No. 31 Daniela Hantuchova.
Eighth-seeded Stanislas Wawrinka, who won the recent Chennai Open, was the first man into the next round, advancing after just 15 games when Andrey Golubev retired with an injured left leg.
Other winners were third-ranked David Ferrer, No. 7 Tomas Berdych, No. 9 Richard Gasquet, No. 14 Mikhail Youzhny, No. 17 Tommy Robredo, No. 19 Kevin Anderson, No. 23 Ernests Gulbis, No. 29 Jeremy Chardy, No. 32 Ivan Dodig and American Sam Querrey.
On Tuesday, in the tougher top half the men's draw, top-seeded Rafael Nadal, Wimbledon champion Andy Murray and Roger Federer are all in action.
