Melbourne, Australia (SportsNetwork.com) - World No. 1 Serena Williams and former top-ranked star Venus Williams secured berths in the quarterfinals at the 2015 Australian Open. Serena dropped the first set before rallying to top rising 24th-seeded Spaniard Garbine Muguruza 2-6, 6-3, 6-2 in two hours at Melbourne Park. Muguruza stunned Serena at the French Open last year, handing the American, who won just four games in that match in Paris, the worst loss of her Grand Slam career in the process. The 33-year-old American great blitzed her 21-year-old opponent with 17 aces and won 38 of 49 first-serve points on Monday. It was a great match -- congratulations to Garbine, she played so well, Serena said. The 18-time Grand Slam champion and reigning U.S. Open titlist owns five Aussie Open titles, but none since 2010. Her quarterfinal opponent will be 11th-seeded Slovak Dominika Cibulkova, who doused on-the-mend Belarusian star Victoria Azarenka, 6-2, 3-6, 6-3. Azarenka led 2-0 in the third set, but couldnt hold on against the diminutive Cibulkova. Today I wasnt thinking about the score, I was just going for it, Cibulkova said. And when I was up, I was going for it even more. I always have tough matches with Vika. The tennis she plays goes well with mine, Cibulkova added. Cibulkova was last years Aussie runner-up to since-retired Chinese star Li Na. The former world No. 1 Azarenka is a two-time Aussie Open champ and two-time U.S. Open runner-up. Her 2014 season was interrupted by a foot injury and shes been trying to re-locate her game since last spring. In other fourth round action on Day 8 of the fortnight, an 18th-seeded Venus remained undefeated in 2015 by surprising sixth-seeded former Wimbledon runner-up Agnieszka Radwanska 6-3, 2-6, 6-1 and rising Madison Keys vanquished fellow American Madison Brengle 6-2, 6-4. Brengle reached her first-ever WTA final in Hobart two weeks ago. Venus will clash with the 19-year-old Keys in an all-American quarterfinal on Wednesday. Venus is a seven-time Grand Slam champion who was the 2003 Aussie runner-up to her younger sister. Shes a perfect 9-0 this year, including a title in Auckland three weeks back. The 34-year-old Venus was asked what her inspiration has been to keep plugging away all these years. Definitely my sister Serena, she replied. Shes just the ultimate champion. She definitely gives me a lot of inspiration. And of course all of my fans, whove always stayed behind me. Keys will play in her first-ever Grand Slam quarterfinal when she faces Venus. It feels really good, she said. My mom texted me before the tournament. She said, Its your last Grand Slam as a teenager, and sent me a bunch of grandma faces. Im like, Thanks for reminding me mom! Thank you. Love you. But its huge. Its my last Slam as a teenager. I hope I can keep it up. The quarterfinals will get underway Tuesday, as second-seeded former No. 1 Maria Sharapova will battle seventh-seeded Wimbledon runner-up Eugenie Bouchard and third-seeded French Open finalist Simona Halep will take on consistent 10th-seeded Russian left-hander Ekaterina Makarova. Sharapova is 3-0 all-time against the Canadian Bouchard, including some French Open match wins in 2013 and last year, while Halep is 1-0 lifetime versus Makarova. The reigning French Open champion Sharapova was the Aussie champ in 2008 and runner-up in 2007 and 2012.

Louis Blues, having added Ryan Miller and Steve Ott from Buffalo, remain the No.CHARLOTTE, N.C. - Kemba Walker is beginning to emerge as the multifaceted point guard the Charlotte Hornets hoped he would become.Walker is off to the best start of his four-year career, entering the week third in the NBA in assist-per-turnover ratio.He did little to hurt those numbers on Monday night. Walker scored 18 points, handed out nine assists and committed just one turnover as the Hornets coasted to a 110-82 victory over the Denver Nuggets.Growing up, I have always been turnover-prone because I was always playing at one speed, Walker said. Now Im trying to mix up my speeds and make the right passes.Walker has 161 assists on the season to 41 turnovers, nearly a 4 to 1 ratio which ranks behind only Chris Paul and J.J. Barea.I want to take care of the basketball, Walker said. Its really important and something Im trying to be conscious of this year because when we dont turn it over it gives us a higher percentage of winning games.Hornets coach Steve Clifford said Walker is developing into one of the leagues better pick-and-roll point guards.Hes in the paint in every pick-and-roll, Clifford said. And he can score, but hes (also) kicking the ball out to teammates.Al Jefferson shook off some early tightness in his lower body and scored 22 points for the Hornets, who extended their winning streak to a season-high three games. Rookie P.J. Hairston recorded his first career double-double with 10 points and 10 rebounds.Jefferson and Walker combined to shoot 15 of 25 from the field and neither player saw action in the fourth quarter with the game well in hand.Charlotte improved to 3-0 since Gerald Henderson replaced the injured Lance Stephenson in the starting lineup. Stephenson, who has been the subject of trade rumours, is out at least one more game with a groin injury.While the Hornets appear to be playing their best basketballl without Stephenson, Clifford said the challenge is to work the teams big-name free agent acquisition into the mix and become even better.ddddddddddddIm looking at it and saying as talented as he is, what we can we become playing like this with him playing well also? Clifford said. And also what things are good that he can add to the team and who should he be on the floor with? Thats what we have to figure out.Ty Lawson had 18 points for Denver, which had its two-game winning streak snapped.This one was never close.The Hornets took control early, building a 58-40 lead at halftime behind 57 per cent shooting from the field. Jefferson and Walker led the way, combining to go 12 of 16 from the field for 32 points before the break.With no scoring option to complement Lawson, the Nuggets never mounted a serious comeback attempt in the second half. The Hornets emptied the bench midway through the fourth quarter up by 30 points.I dont know what to say, Nuggets coach Brian Shaw said. You have eyes, you saw it. It was an ugly, nasty game. We just have to flush it down the toilet.___TIP-INSNuggets: Timofey Mozgov suffered a laceration to his left eye during the first quarter and received four stitches. He returned to the game but only played 15 minutes.Hornets: Jeffery Taylor saw his first action of the season following a 24-game suspension. Taylor was rusty, misfiring twice from the field. He also clanked free throw attempts.JEFFERSON SCAREClifford took Jefferson out of the game as a precaution five minutes in after the 6-foot-10 didnt leave his feet on a baseline move and threw up an airball. Jefferson said he simply was tight.Clifford said he wanted to be sure, adding, Im into challenges, but Im not into playing a month without him.UP NEXTNuggets: At Brooklyn on Tuesday night.Hornets: At Milwaukee on Tuesday night.
