Worldnumber one Serena Williams ruthlessly defeatedCarla Suarez-Navarro 6-2, 6-0 to win her eighth title in Miami on Saturday.

The33 – year old secured her third consecutive title at Crandon Park in Florida.  She also became only the fourth woman to winthe same WTA tournament eight times, of the 15she has entered, with her first title in 2002. This is equallingMartina Navratilova, Chris Evert and Steffi Graf’s records; Navratilova, who presented the trophy, won Chicago 12 times, the mosttitles by a woman at any tournament.

Forthe 26 –year old Suarez-Navarro this was the biggest match of her career; she hada fabulous two weeks of Tennis and beat Williams'sister Venus in the quarter-final.

 She has now movedto top ten seed. 

TheSpaniard began well and held her serve through the first five games, but theAmerican moved up a gear, took control and served successive aces to gain a 4-2advantage in the opening set. It was allone-way traffic thereafter, and the first set was over at 6-2.

Suarez– Navarro had a chance for a break in the first game of the second set, butWilliams held on and then served three un-returnable serves. This paved the way for a period of completedominance for the American, as she won 21 out of 22 points on her first serve,to bagel her opponent in the second-set. Suarez-Navarro, who won just five pointsduring the second set, had no answers for the overwhelming power of Williams.

The match was over in just 56 minutes.

Williamswas in great form in Miami, although she had to pull out of her semi-final in IndianWells last month, because of a knee injury. The American, who won her 19thGrand Slam title in Australia this year, also claimed her 700thcareer victory earlier in this tournament, which she considers her home event,as she only lives 90 minutes away from Crandon Park.
