Serena Williams, Djokovic Nab Tennis Wins

After last year's infamous twirl-gate, Serena Williams is sporting a new look this Australia Open: a yellow two-piece outfit with a crop top and pleated skirt.

"It's built for speed,'' she said.

That was definitely the case Friday. Williams played her third-round match so fast and furiously it was if she needed to dash out and chase down a cell phone thief. Or make sure that teenage opponent Daria Kasatkina could get home well before curfew.

Serena's 6-1, 6-1 victory took just 44 minutes, the shortest match so far at this year's Australian Open.

Williams says she chose the pleats because they are classic and the top because, well, "I live in a crop top, sleep in crop tops. I'm often never seen without one. So I thought it would be really fun to play in one."

She said she has been wearing many different designs and wanted to push the envelope again.

"Just bring pop culture to tennis, kind of make it really fun,'' she said of the design. "A lot of things you see on stage and just in that pop culture world, I wanted to bring that youth and that fun-ness to it.''

This match was a distinct contrast to much of Serena's 2015 Grand Slam season. Despite winning the first three majors and nearly completing a Calendar Slam, Serena lost the first set eight times and played three sets a dozen times, repeatedly placing her back against the wall and toes along the edge. She played so many sets at Roland Garros (five three-set matches) that she probably is still kicking the red clay from her shoes.

 A five-time champion Down Under, even top-ranked Novak Djokovic has to make concessions.

Relegated to Margaret Court Arena for the first time in nine years, Djokovic took down No. 28 Andreas Seppi 6-1, 7-5, 7-6 (6) in the third round at the Australian Open.

Scheduled to play at the same time as WTA No. 1 Serena Williams, Djokovic appeared unaffected by the change of venue to start the match. The same couldn't be said for his coach, Boris Becker, who was still trying to find his seat as the first point was struck.

With a break-point opportunity in the second game, Djokovic threaded a backhand down the line and eventually took the opening frame in 25 minutes.

But what began as routine rout from Djokovic turned into a dogged 2-hour, 21-minute affair. He bounced his racket in frustration multiple times and looked to his box, pleading for answers.

Finally, at 5-5 in the second set, Djokovic won a spectacular 32-point rally to break his opponent and subsequently held to take the commanding lead.
