After a devastating injury in the semifinals of the 2022 French Open, Alexander Zverev bounced back this season, capping off the year as World No. 7.

The German did not make a strong start, with a second round exit at this year's Australian Open. He found his footing on clay and made a deep run at the French Open, where he reached the semifinals. He lost to Casper Ruud, who eventually lost to the reigning French Open champion Novak Djokovic in the final.

At the 2023 Wimbledon Championships, Zverev advanced to the third round of the tournament where he lost to Matteo Berrettini. The 26-year-old picked up his game in the second half of the season, clinching two titles - the Hamburg European Open and the Chengdu Open. He also made a quarterfinal exit at the US Open where he was defeated by Carlos Alcaraz.

Zverev took to Instagram to reflect on his 2023 season and thanked his supporters for their unwavering belief in him.

"What a year! From having uncertainties whether I would ever come back to my level to finishing number 7 in the world, winning two @atptour titles and making it to @nittoatpfinals. Thanks to everyone for the incredible support and for believing in me," Zverev wrote.

Alexander Zverev ended the 2023 season with 55-27 win-loss record.
