#5 Andre Agassi, 1994 US Open
Most people may not be acquainted with the fact that Andre Agassi won one of his eight Grand Slam titles as an unseeded player and this title actually came after he won the Wimbledon in 1992. 1994 wasn’t turning out to be a good year for Agassi as he missed the Australian and endured second and fourth round exits at the French Open and Wimbledon respectively.
However, he rebounded brilliantly at the US Open. Agassi beat 12th seed Wayne Ferreira in the third round before beating 6th seed Michael Chang in a marathon encounter in the fourth.
In the quarter-finals, Agassi defeated Thomas Muster before beating 9th seeded US compatriot Todd Martin in the semis to set up a final clash against 1991 Wimbledon champion and 4th seed Michael Stich.
Agassi bashed the German 6-1 in the first set. Stich was showing resilience but his American opponent held his nerve and won both the second and third set by 7-6 and 7-5 respectively to win his second Grand Slam title.
#6 Gustavo Kuerten, 1997 French Open
Mats Wilander won his maiden ATP title at the 1982 French Open but since then, there was no player who won his first ATP title at a Grand Slam event. However, that streak was broken at the 1997 French Open.
20-year-old Brazilian Gustavo Kuerten produced one of the biggest upsets of the tournament when he defeated the 1995 French Open champion and clay-court specialist Thomas Muster in the third round and then defeated Ukrainian Andriy Medvedev in a nail-biting five-setter to reach the quarter-finals where he would face defending champion Yevgeny Kafelnikov.
Kuerten stunned the Russian in five sets to reach the semi-finals where he defeated qualifier Filip Dewulf from Belgium to reach his maiden Grand Slam and ATP final. In the final, Kuerten was up against two-time champion Sergi Bruguera.
The Brazilian shocked the Spaniard in straight sets to win his maiden Grand Slam -becoming the first Brazilian to win a Grand Slam title in nearly 40 years since Maria Bueno's Wimbledon triumph in 1959.
