Answer
Sampras won 5 US Open titles, making him one of the most successful players in the tournament's history. His first victory came in 1990, and he went on to win again in 1993, 1995, 1996, and 2002. Sampras's success at the US Open was due in part to his powerful serve and aggressive baseline play. He was also known for his mental toughness and ability to perform under pressure.
