In September, Sampras captured his first Grand Slam title, at the US Open. Along the way, he defeated sixth-ranked Thomas Muster in the fourth round and third-ranked Ivan Lendl in a five-set quarterfinal, breaking Lendl's streak of eight consecutive US Open finals. He then defeated 20th-ranked McEnroe in a four-set semifinal to set up a final with fourth-ranked Agassi. Sampras beat Agassi in straight sets to become the US Open's youngest-ever male singles champion at the age of 19 years and 28 days. He played five more tournaments and won the Grand Slam Cup to complete his year.
