Serena Williams has won her sixth Wimbledon title with a straight sets victory over Garbine Muguruza of Spain.

Williams, 33, moves on to 21 career Grand Slams and also completes her second 'Serena Slam' – holding all four major titles in world tennis - with a 6-4 6-4 win on Centre Court.

After winning the opening set, the American looked to be cruising to another triumph at SW19, only for Muguruza to come roaring back from the face of defeat to win three straight games.

But it only delayed the inevitable as Williams held on to continue her dominance of women's tennis.

Muguruza endured a dream start to the opening set as she swiftly moved into a 2-0 lead against her nervous-looking opponent. A powerful ace moved her further ahead as Williams grew visibly frustrated, while the underdog was calmness personified as she saved two break points at 4-2.

The world no. 1 came roaring back, however, breaking back to move level at 4-4 on her second attempt. It provided the momentum shift the American desperately needed. A double fault from the Spaniard allowed Williams to seal the set with a typically thunderous forehand and suddenly the clumsy start she endured to the set seemed a distant memory.

It could have been easy for Muguruza to wilt after a dispiriting conclusion to the opening set but the 21-year-old started the second with her head held high, holding to love in the second.

The resistance would be short-lived however as Williams began to dominate the set, forcing unforced errors from the Spaniard as she broke again at 3-1.

Muguruza could do little to stop the onslaught as her opponent raced towards victory but did manage to halt Williams in the seventh game, breaking her opponent to stay in the contest.

Staring at defeat, Muguruza struck back again in front of an astonished Centre Court, holding serve to pull the contest back to 5-3 before saving match point with a tremendous return.

She followed that up with another huge forehand to break Williams for the third time in the match, earning a standing ovation from around the court as she closed the gap to 4-5. It could only delay the inevitable, however.

A second set that raced by ended on a peculiar moment as Muguruza challenged an over-hit forearm, but then acknowledged it was a lost cause, handing the win to Williams.

"I enjoyed a lot. I cannot talk. I don't have words to say how i feel. I'm very proud and happy to be here," Muguruza told BBC Sport after her defeat.

Asked if grass is now her favourite surface, she replies: "Yes. In Spain we don't have that much grass but I'm going to change things now."
