Madison Keys is into her second Australian Open semifinal after taking out No. 4 Barbora Krejcikova 6-3, 6-2 on Tuesday.

Keys is now 11-1 on the year and is on a career-best 10-match winning streak.

She took down Krejcikova behind 27 winners, including 11 aces. She also managed just 21 unforced errors. Krejcikova, meanwhile, managed only 12 winners, which were outpaced by 28 unforced errors.

It’s the fifth Grand Slam semifinal of the American’s career and her first since the 2018 US Open. Her best finish in a Grand Slam to date is a runner-up showing against Sloane Stephens at the 2017 US Open.

Keys will now look to the semifinals, where she will face off against world No. 1 Ash Barty. Barty continued her dominant run on Tuesday, taking down No. 21 Jessica Pegula 6-2, 6-0 in a mere 63 minutes. So far, Barty has gone the entire Open without playing a third set.

“I think she’s definitely living in everyone’s head a little bit,” Pegula said of Barty after the match. “I don’t think anyone is going to feel great going out to play her because they know they have to play really well.”

Barty and Keys have faced off three times before, with Barty holding the edge 2-1. Their last match came at the 2019 French Open, when Barty won en route to the title.
