Defending champion Mirra Andreeva exited Indian Wells in dramatic fashion on Monday, losing to unseeded Katerina Siniakova 4-6, 6-7(5), 6-3 in a third-round clash marked by racket smashing and crowd confrontations.

Andreeva hurled her racket at the hard court after dropping the second-set tiebreaker. She then smashed the equipment multiple times, with officials issuing her a code violation for the outburst.

The fireworks didn't end there. After Siniakova clinched match point, Andreeva threw her racket again. She subsequently shook hands at the net, then stormed off the court while shouting at spectators.

Siniakova advanced with the upset victory, as the Czech player capitalized on Andreeva's unraveling to claim the win.

"I knew the pressure was on her. I was trying to enjoy it, because finally I was on the other side when I have nothing to lose," Siniaková told The Tennis Channel.

"She's an amazing player. You need to play long rallies, you need to do it on your own."

Mirra Andreeva Addresses her Indian Wells Outburst

In her post-match press conference, the 18-year-old expressed regret for her outburst, acknowledging her behavior fell short of her standards. The teenager said she wasn't proud of how she managed her emotions during the loss.

Andreeva told reporters she needs to work on her temperament, emphasizing urgency in addressing her on-court conduct. The defending champion called it something she must fix soon rather than later.

"I'm not really proud of how I managed it. I'm not really proud of how I handled it in the end," she told reporters.

"Those are the things that really need to work on soon. I don't know. Not in the future, but whenever I get the chance."

The loss marks a disappointing run for Andreeva, after the Russian star won the prestigious California tournament last year. Her exit leaves the draw wide open for a new Indian Wells champion.

Tennis star Aryna Sabalenka has done it again, with the world No. 1 taking home the WTA Player of the Year award for a second straight season on Monday — becoming just the seventh woman to earn the honor back-to-back.

Sabalenka won Player of the Year in dominant fashion, garnering nearly 80% of the media vote after leading the 2025 WTA Tour in wins, titles, and finals appearances — all while racking up a record $15 million in prize money.

The 27-year-old spent the entire year as the sport's No. 1 player, all while reaching three of the four Grand Slam finals en route to winning the 2025 US Open.

After an elite season, US rising star Amanda Anisimova won the WTA Most Improved Player honor for reaching a career-first two Grand Slam finals while jumping from No. 34 to No. 4 in the rankings.

Following her own breakout 2025 campaign, 19-year-old Canadian talent No. 18 Vicky Mboko took home Newcomer of the Year, with Swiss No. 11 Belinda Bencic earning Comeback Player of the Year after returning from pregnancy in stellar form.

The world's top duo of Czechia's Katerina Siniakova and US standout Taylor Townsend also capped their 2025 season with hardware, earning the sport's Doubles Team of the Year.

No. 1 seeds Barbora Krejcikova and Katerina Siniakova clinched the Australian Open doubles title Sunday, coming from behind to defeat Anna Danilina and Beatriz Haddad Maia 6-7(3), 6-4, 6-4.

The Czech duo’s Australian Open win puts the team one step closer to capturing a career Grand Slam, needing a US Open title to go along with their two French Opens, Wimbledon trophy and Olympic gold medal.

Danilina and Haddad Maia challenged the No. 1 seeds throughout the 2 hour and 42-minute final in the pair’s Grand Slam debut. Firing 22 winners to the Czech team’s 19, the unseeded duo made Krejcikova and Siniakova work, but ultimately couldn’t outlast the champions’ resolve.

“We were fighting hard to get the Australian one,” said Siniakova in the team’s post-match press conference. “So it’s just really exciting and super happy because the focus on the Grand Slam … you want to get these titles, the big ones, so I’m just extremely happy that we got it.”

The Australian Open title marks Krejcikova and Siniakova’s fourth Grand Slam trophy, improving to 4-1 in major finals.
