Murray becomes New World No 2, wins Miami final

Serena Williams also won

Andy Murray came from a set down to beat David Ferrer in a Sony Open final that went the distance and leapfrog Roger Federer into the world No 2 spot in the rankings

Though far from his best for long periods, Murray had to dig deep after Ferrer got off to a blistering start by taking the first set 6-2

One point from defeat in the last set, Murray skipped a forehand off the far baseline to stay in the match Sunday. He then dominated the tiebreaker, while Ferrer appeared to cramp and collapsed to the court after one rally.

Murray also won the title in 2009. His path to this year's championship was made easier because Roger Federer and Rafael Nadal skipped the tournament and Novak Djokovic lost in the fourth round.

Women's world No 1 Serena Williams also won her final match against World No 2 Maria Sharapova.

World number one Serena Williams fought back from a set down to beat Maria Sharapova 4-6 6-3 6-0 and win the Sony Open for a record sixth time on Saturday as she continued her dominance over her closest rival.

With the win, Williams, who struggled with her serve in the first two sets, becomes only the fourth woman in the Open era to win the same WTA tournament six times, joining Martina Navratilova, Chris Evert and Steffi Graf.

"I finally have some record," Williams said. "Like it's really cool. I can't seem to catch up with Margaret Court or Steffi or anything. I'm really happy to have something right now, so it's exciting.

"Maria played really the best I have seen her play, and I think she was moving unbelievable and she was hitting winners from everywhere. .... How did I end up winning when I actually wasn't on top of my game?"

Second-ranked Sharapova has now lost to Williams in their last 11 meetings and has not beaten the American since her two victories in 2004.

To add to the pain, the match was Sharapova's fifth Miami final and her fifth defeat.
