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.

Madison Keys cruised past No. 8 seed Paula Badosa 6-3, 6-1 on Sunday to advance to the Australian Open quarterfinals.

The American got off to a flying start, dropping only five service points during the opening set. In the second set, Keys won five straight games to finish off the match in 69 minutes.

The victory secured Keys her eighth career Grand Slam quarterfinal and first Australian Open quarterfinal appearance since 2018.

The 26-year-old has had a dominant start to 2022, kicking off the season with a 10-1 record. Keys will look to keep the streak going when she faces off against No. 4 Barbora Krejcikova.

The Czech star downed former Australian Open champion Victoria Azarenka in straight sets to earn a quarterfinal matchup against Keys.

Madison Keys’ strong start to the new year continued at the Australian Open on Monday, with the American upsetting 2020 champion Sofia Kenin 7-6(2), 7-5 in the first round.

Keys recorded 31 winners, including 15 aces, to take down No. 11 seed. The victory was the 43rd of Keys’ WTA career and her sixth straight.

Keys, the former world No. 7, was coming off of a win Saturday at the Adelaide International tournament for her first WTA title since 2019. She now holds a 3-1 head-to-head advantage over Kenin.

Kenin, the 23-year-old American, was the third top seed to fall Monday after Coco Gauff dropped her first-round match and Ons Jabeur withdrew from hers due to injury.

Keys, 26, will take on Jaqueline Cristian of Romania in the second round. Cristian defeated Greet Minnen 7-5, 6-4 on Monday.

Madison Keys cruised past Alison Riske 6-1, 6-2 in the Adelaide International 2 final to clinch her first title since 2019.

The 26-year-old American fired 24 winners to power past her fellow countrywoman, never facing a breakpoint during the 66-minute match.

Keys entered the Australian Open tune-up event as World No. 87 and defeated No. 2 seed Elina Svitolina, No. 8 seed Liudmila Samsonova and No. 3 seed Coco Gauff in her charge to the final. The former World No. 7 will break into the Top 60 following her victory in Adelaide.

Keys will face a tough first-round matchup at the Australian Open, facing off against 2020 Australian Open champion and World No. 12 Sofia Kenin.
