The Spaniard finished as runner-up to the American's sister, Serena, in this same fixture two years ago but claimed some redemption after sailing to this year's crown, per the tournament's Twitter account:
Williams pushed her foe to the brink in the opening set before Muguruza's stamina appeared to overwhelm the five-time All England Club winner en route to a bagel in the second set.
Hardly new to competing on this stage, Williams was gracious in defeat and was quick to heap praise on the newest Wimbledon champion:
Muguruza was technically astute and showed she learned from her defeat to the younger Williams sister in the 2015 final. In the process, she sealed her place in the record books, per ESPN Stats & Info:
The early stages were tense as both players held their serve with relative ease, but the two began to open up at three games apiece.
Williams was denied the first break of the match and then was forced to save one of her own before taking a 4-3 lead, at which point the New York Times' Ben Rothenberg highlighted how finely balanced the meeting was:
Leading 5-4 with her opponent on serve, things started to turn against Williams—appearing in her ninth Wimbledon final—as she missed two set points from 15-40 and then conceded the opening break of the match to trail for the first time.
Those back-to-back games were the beginning of a terrifying streak on Muguruza's part, and she earned the praise of BBC 5 Live Sport commentator Mary Pierce:
Williams would come to regret those missed opportunities. It appeared all her motivation was drained in the second set, but perhaps the quality of her opponent just became too much.
The occasion didn't daunt Muguruza, and the IBM SlamTracker showed Williams' 10 unforced errors in the final six games dwarfed the winner's minuscule tally of one.
So tidy was Muguruza's performance that it was almost poetic she barely had to move a muscle to seal the victory. Williams' deep backhand—initially ruled in—was shown to have sailed long when the Spaniard challenged mid-point:
The 23-year-old steamrolled her way to a maiden title at SW19 on the back of an unstoppable nine-game run, and tennis writer Tumaini Carayol noted Muguruza's star continues to glitter on the biggest stages:
Given her age, there's no telling where the ceiling is, and Muguruza again confirmed her place as one of the top draws in tennis, adding a Wimbledon title to her 2016 French Open triumph.
Meanwhile, the 37-year-old Williams can be proud of her ongoing run as a force in the sport.
