Diana Shnaider was still a teenager when she won her first WTA title with victory at the Thailand Open in Hua Hin. The lefthander also had a successful junior career, reaching No. 2 in the World Junior Rankings and winning girls’ doubles titles at three of the four Grand Slams: Wimbledon in 2021, and the Australian Open and US Open in 2022. In 2026, she continued to build on that momentum, reaching the doubles final at the Madrid Open before winning the Internazionali BNL d’Italia doubles title in Rome. She then achieved another major milestone in 2026, by advancing to the semifinals of Roland Garros, marking her first Grand Slam semifinal appearance.
