A look into Sebastian Korda' 2024 season so far

Sebastian Korda has had a rollercoaster of a season so far in 2024.
The American kicked off his season at the Brisbane International. He entered the tournament as the fifth seed but was defeated in the first round by Yannick Hanfmann in straight sets.
Korda then saw some success at the Adelaide Open. He put up an impressive performance against Lorenzo Sonego in the first round to defeat the Italian in straight sets. He kept this form in the quarterfinals as well, comfortably defeating Christopher O'Connell to set up a semifinals clash against Jiri Lehecka. The Czech international dominated the clash, bringing Korda's run to an end.
The 23-year-old was most recently seen at the Australian Open 2024. After surviving a five-set thriller against Vit Kopriva in the first round, the American comfortably saw off Quentin Halys in the second round in straight sets. In the third round, Korda faced Andrey Rublev, who proved to be too much for him as the Russian defeated him in straight sets.
Sebastian Korda will next be seen at the Open 13 and will be facing Hugo Grenier in the first round on February 6.
