Australian Open Tennis

MELBOURNE, Australia (AP) — After backhanding the ball into the crowd when Carlos Alcaraz sent his service return too long, Alexander Zverev screamed. He shook both arms in a victory celebration and again he screamed, a mix of triumph and relief.

Any self-doubt that he could contend for major titles again were expunged in a 6-1, 6-3, 6-7 (2), 6-4 quarterfinal win on Wednesday over the brightest rising star in tennis, earning Zverev a spot in the Australian Open semifinals against Daniil Medvedev.

He'd missed a chance to serve it out in straight sets but didn't waste his second opportunity.

A serious ankle injury at the 2022 French Open and the ensuing layoff made him wonder if he really was good enough to win a Grand Slam title.

A pending trial in a German court over an assault allegation dating back to 2020 has had critics questioning his status on the tour. He has denied the accusations and declined comment on the judicial proceedings scheduled for May.
