Both players set up three break points during the hard-fought opener, but only Muguruza was able to convert, scoring a crucial break with the scoreline at 5-5 and going on to serve out the set.
An inspired Garbine Muguruza stormed to her first Wimbledon title on Saturday, blowing away in-form American Venus Williams 7-5 6-0 with arguably the performance of her career after tight and tense early exchanges.
Wimbledon victory also rockets Muguruza into the top 30 prize money earners in WTA history with a total $14.1m amassed in six years as a professional.
In the semifinals, she defeated Magdalena Rybarikova to set up the summit clash against the seven-time Grand Slam Champion. Of course I'm nervous because I always dreamed about winning it, but I was composed. "That's where I want to be".
Luckily, when Serena's not around, she has close friend and feminist Andy Murray to have her back.
Prompted to offer a message for coach Sam Sumyk, absent as his wife is due to give birth, Mugurza held aloft the trophy and gleefully declared: "Here it is!" "Here I am!" said Muguruza after the match.
She said: 'Oh I miss you.
"She's still motivated to go for more and still has the hunger, which is also very surprising".
The 23 year year-old stopped the remarkable run of 37 year-old Venus Williams by winning the first women's final of Wimbledon.
Although the comment drew laughs from the crowd and a rueful smile from Williams, it is demonstrably true.
After that win she had been tipped for great things, says Charlie Eccleshare in the Daily Telegraph.
Immediately at the start of the second set, the Spaniard took the serve from Venus and in the rest of the match, the 37-year-old couldn't do anything against the fantastic game of her opponent.
Garbine Muguruza already knew what it's like to lose to a Williams in the Wimbledon final.
The 35-year-old Grand Slam champion was having none of it, taking to twitter to call out the comment.
