Sho Shimabukuro

Following his first two career Challengers titles, one in January in Nonthaburi, defeating Arthur Cazaux and in May 2023, Shimabukuro reached the top 200 at world No. 178 on 22 May 2023.

In June, Shimabukuro defeated Liam Broady in straight sets to reach the quarterfinals of the 2023 Nottingham Open. As a result, he reached a new career ranking of No. 172 on 19 June 2023. In the next grass court Challenger event, the 2023 Ilkley Trophy, he reached also the quarterfinals as a lucky loser but retired this time against Arthur Cazaux. He climbed another 10 positions to world No. 162, one week later, on 26 June 2023.

Shimabukuro made his Grand Slam debut after qualifying for the main draw of the 2023 Wimbledon Championships where he lost to 21st seed Grigor Dimitrov. He entered the tournament in Washington as a lucky loser and won his first career ATP tour level match defeating Lloyd Harris but lost to Christopher Eubanks.

Shimabukuro also qualified for the main draw on his debut at the US Open. He qualified for the 2023 Astana Open and defeated Roberto Carballés Baena, his second career ATP tour win.

Shimabukuro received a wildcard for the main draw of the ATP 500 2023 Japan Open, and for the qualifying draw at the same tournament in 2025 where he qualified and upset fifth seed Tomáš Macháč for the biggest win of his career and only his fifth ATP win.
