Serena in dream Sharapova final, Murray makes decider

Arch-rivals Serena Williams and Maria Sharapova set up a dream Australian Open final Thursday while Andy Murray ground down Tomas Berdych to give himself a fourth crack at winning the Melbourne Park title.
Williams battled past gallant fellow American Madison Keys while Sharapova demolished Russian compatriot Ekaterina Makarova to ensure the top seeds meet in Saturday's showpiece.
The world's best two players have history and the odds are stacked in Williams' favour, with the 33-year-old holding a major psychological advantage.
She has a 16-2 record against Sharapova, with the Russian five-time Grand Slam champion losing their every encounter since 2004.

An impressive Murray swept into a fourth Australian final in six years as he zeroed in on the elusive title, dousing big-serving Czech Berdych 6-7 (6/8), 6-0, 6-3, 7-5.
There was plenty of friction between the two over Berdych's decision to hire former Murray team member Dani Vallverdu as his coach, with some steely glares at each other during the changeovers.

"I was disappointed to lose the opening set after I had a couple of chances at the end but I felt I was playing better as the set went on and I was very aggressive at the beginning of the second set," said the British sixth seed.

"In the beginning I was feeling quite rushed and then I got more aggressive and made him do more running."
Awaiting him in Sunday's final will be world number one Novak Djokovic or defending champion Stan Wawrinka, who play their blockbuster semi on Friday.
Despite the ominous statistics, Sharapova has been in outstanding touch and blew away fellow Russian Makarova 6-3, 6-2 on a blustery afternoon on Rod Laver Arena.
She is now in her fourth Australian final, having won in 2008.
Williams was made to work harder by rising teen Keys, who saved eight match points.
Coached by former US great Lindsay Davenport, Keys forced Williams to a first set tiebreak before her illustrious opponent took charge to win 7-6 (7/5), 6-2.

"I was just happy to get through it today," said Williams. "My theory now is to relax and just play the next match as best I can.
