MELBOURNE, Australia -- Madison Keys continued her resurgent 2022 season by advancing to the Australian Open semifinals for the first time in seven years.
And resurgent might be a major understatement.
Her 6-3, 6-2 quarterfinal win over French Open champion Barbora Krejcikova on Tuesday was her 10th match win in a row and 11th of the new year. She served 11 aces, 27 winners and dropped just one service game.
Her run in '22 includes five wins so far at Melbourne Park, starting with a straight-sets victory over 2020 Australian Open winner Sofia Kenin, plus five in winning the Adelaide International -- her first title since 2019 --- and one at an earlier Melbourne tournament.
Her total number of wins in all of 2021? That same number, 11.
"I did everything I could to rest this offseason and focus on starting fresh and new ... starting from zero and not focusing on last year," Keys said in her on-court interview. "I think it's going well so far!"
Last week, Keys gave more details on how terrible 2021 was for her.
"I was just at a very high anxiety level all of the time," Keys said. "I wasn't sleeping as well. It felt like there was literally a weight on my chest just because I became so focused and obsessed with it that I wasn't enjoying really anything because it's all that I was thinking about."
Her year-end ranking slumped to 56th, and it was the first time since 2014 she'd finished outside the top 20.
In 2015, Keys lost an Australian Open semifinal to Serena Williams, her first trip to the final four at a major. She reached the final at the 2017 US Open and semis at Roland Garros and the US Open in 2018, but hadn't made it back to the last four in a Grand Slam since then.
"I'm seven years older and it's not my first semifinal of a Slam," Keys said. "I think I'm a little bit more prepared this time around than I was all those years ago."
Krejcikova took a medical timeout while trailing 5-2 in the first set from what might have been heat stress, and appeared to be lethargic at times during the 35-minute second set.
Temperatures was peaking toward 32 degrees Celsius (90 Fahrenheit) under almost cloudless skies.
"It was the heat with some physical conditions that started to bother me after five games," Krejcikova, who is still playing in the doubles draw, said. "I mean, from there on, you know, I just couldn't put it together.
"I have been struggling with something. Yes, it was happening and I didn't feel good. I just don't want to talk about it because I think Madison, she really deserves the win and she really deserves to get the credit. "
