#1 Lleyton Hewitt (2001)
20-year-old Lleyton Hewitt of Australia arrived at the 2001 US Open after winning titles in Sydney, Queens and s-Hertogenbosch.
In only his third appearance at Flushing Meadows, Hewitt had a straight-set first-round win over Swede Magnus Gustafsson before overturning a two-sets-to-one deficit in the second round against James Blake to reach the third round.
Successive wins over Spaniard Albert Portas and Germany's Tommy Haas carried Hewitt onto his second quarter-final at the US Open.
In a hard-fought last-eight clash, Hewitt dropped the opening set and then the fourth set against the big-serving American teenager Andy Roddick before taking a 6-7(5), 6-3, 6-4, 3-6, 6-4 win. It made him return to the semi-finals where he dropped only four games against Kafelnikov to reach his first Grand Slam final against 13-time Grand Slam champion Pete Sampras.
The American's bid to land a record-equalling fifth US Open title was thwarted for a second straight year in the title match, as Hewitt emerged a straight-set victor to win his maiden Grand Slam title.
