Who was the last American man to win the US Open singles title? Andy Roddick was the last American champion.

Roddick won the 2003 US Open at age 21, defeating Spain’s Juan Carlos Ferrero 6–3, 7–6(2), 6–3 in the final. The victory gave Roddick his first and only Grand Slam singles title and made him the first American man to win the US Open since Pete Sampras in 2002.

His run capped a breakthrough season. Roddick won six ATP titles in 2003, including the US Open, and briefly became the world No. 1 later that year. His defining weapon was a powerful serve: he struck 23 aces in the final and used it to control short points against Ferrero.

The wording can cause a small but important mix-up. Roddick is the last American man to win the US Open men's singles title, and also the last American man to win any Grand Slam singles title. Andre Agassi reached the 2005 US Open final, and Roddick reached the 2006 final, but neither won.
