Maria Sharapova powers on in search of maiden Miami Masters victory

The Russian has lost in two previous finals

Maria Sharapova powered her way past another opponent at the Sony Open in Miami on Monday as the Russian world number two remains on target to finally claim a tournament that has brought her plenty of heartbreak.

The third seed shrugged off the challenge of Klara Zakopalova, easing to a 6-2 6-2 victory over the Czech to advance to the quarter-finals and inch closer making it fifth time lucky in Florida.

Sharapova was beaten in the last two finals after also falling in the tournament decider in 2005 and 2006, and her determination to go one better this year was evident against Zakopalova, who was helpess in the face of the Russian's power.

Earlier, top seed Serena Williams stared defeat in the face before mounting an exciting comeback to overcome Slovakia's Dominika Cibulkova.

Williams trailed by a set and 4-1 before she reeled off the next five games and ultimately took the match 2-6 6-4 6-2.

"This particular time I just thought to myself, 'I've been down worse. It's nothing new. Just keep fighting,'" Williams told reporters.

"I never give up. It doesn't matter whether it's in life or on the tennis court, I keep fighting. That's what I kept doing today."

Williams closed out the contest with her 14th ace in a battle that lasted a little less than two hours. The American is bidding to become the tournament's first six-time winner, and claim her first title here since 2008.

For Cibulkova, it was another missed opportunity. Last year, she had then top-ranked Victoria Azarenka down 6-1 5-2 but could not finish the job.

On the men's side, second seed Andy Murray overcame some early jitters before advancing past Grigor Dimitrov 7-6 6-3 in their third round encounter.

Murray had issues with his serve early on and fell behind 5-2 in the first set but his Bulgarian opponent was unable to close out the set, suffering as a result of three double faults.

The Briton found his rhythm in the second set and never looked back.

"It was way cooler today with much slower conditions," Murray said. "I was leaving the ball a bit short. Once I started to improve my depth a bit, I made it tough for him."

The reigning U.S. Open Champion will next play Italy's Andreas Seppi. Murray, a Miami winner in 2009, was beaten by Novak Djokovic in last year's final.
