Alexander "Sascha" Zverev (born 20 April 1997) is a German professional tennis player. Zverev has won 26 ATP Tour singles titles, including two majors at the 2026 French Open and 2026 US Open, a gold medal at the 2020 Tokyo Olympics, seven ATP 1000 events, and the 2018 and 2021 ATP Finals. Zverev is a former junior world No. 1, and won a junior major singles title at the 2014 Australian Open. He had an early breakthrough on the professional tour, becoming one of the youngest ATP Challenger Tour title winners in history at the age of 17. As a teenager, Zverev won two ATP titles and upset then–world No. 3 Roger Federer on grass. At 20 years old, he became the youngest player to debut in the top 20 since Novak Djokovic. At the Laver Cup, Zverev played an instrumental role in Team Europe's early success, winning the clinching matches in 2018, 2019, and 2026. After reaching his first major final at the 2020 US Open, he became an Olympic gold medalist in 2021. He suffered an ankle injury at the 2022 French Open, which required an extended recovery period. He rebounded in the following years to re-enter the top 10, where he has since remained a permanent fixture and reached five more major finals. In 2026, Zverev enjoyed his most successful season winning the French Open and US Open, and is guaranteed to rise to number 1 in the world rankings in November 2026.
