Which tennis player won the 1990 US Open men's singles title at age 19?

Pete Sampras won the 1990 US Open men’s singles title at age 19 years and 28 days. He defeated fellow American Andre Agassi 6–4, 6–3, 6–2 in the final to claim his first Grand Slam championship.

The victory made Sampras the youngest US Open men’s singles champion at the time. It also announced the arrival of a player who would become one of the defining champions of the 1990s. Sampras’s serve-and-volley style, especially his powerful first serve, became central to his later dominance on fast courts.

His run included a major quarterfinal victory over Ivan Lendl, ending Lendl’s streak of eight consecutive US Open finals appearances. Sampras then beat John McEnroe in the semifinals before overcoming Agassi in straight sets.

The age clue can cause confusion with Michael Chang, who won the 1989 French Open as a teenager and became the youngest male Grand Slam singles champion at that time. Sampras’s 1990 triumph was specifically the US Open title, and it began a career that produced 14 major singles championships.
