Australian Open 2020 Women's Final: Winner, Score and Twitter Reaction

Sofia Kenin capped off her surprising run at the 2020 Australian Open with a 4-6, 6-2, 6-2 victory over Garbine Muguruza to win the first Grand Slam title of her career. 

At 21 years old, Kenin is the youngest American to win a major since Serena Williams won the U.S. Open in 1999. 

Kenin, the 14th seed, had never advanced past the fourth round in a Grand Slam previously. She started off slowly against Muguruza, coming within one point of falling behind 2-5 in the first set. 

Kenin was able to force a 4-4 tie in the opening set thanks to saving four break points. Even though she wound up dropping the first set, that brief comeback was an indication of what was to come.

Kenin arrived in Australia coming off the best year of her career. She won three singles titles and had notable victories over Williams at the French Open and Naomi Osaka at the Western & Southern Open.

This season started out slowly, however, as Kenin lost in the second round at the Brisbane International and Adelaide International as tune-ups for the Australian Open.

After taking out top-ranked Ashleigh Barty in the semifinals, Kenin completed her masterpiece with 28 winners while converting five of six break-point opportunities.

"My dream has officially come true," she said on the court after her win. "If you have a dream, go for it, because it can come true."

Meanwhile, since Muguruza reached No. 1 in the world rankings and won Wimbledon in 2017, she had just two singles wins in the previous two seasons combined. Coming into the Australian Open unseeded, she knocked off three of the top-10 seeds and didn't drop a set from the third round through the semifinal.

"If people see it because I'm in a Grand Slam final, that makes sense," Muguruza told reporters when asked if she feels like this is a resurgence. "I feel like I was playing a lot of tournaments. I was on the tour. I didn't disappear. I was there. Not reaching final rounds, for sure."

There were moments during the match when Muguruza appeared to be moving gingerly because of a back injury that required a visit from the doctor between the second and third sets.

Still, after reaching the final, Muguruza will move up to No. 16 when the new world rankings are released Monday. Kenin, meanwhile, looks poised for a huge year, and she will jump to No. 7 in the world rankings.
