All the instances when an unseeded player won a Grand Slam Singles title

#7 Goran Ivanisevic, 2001 Wimbledon

Goran Ivanisevic was the first wildcard to win a Grand Slam

One of the finest left-handed players during the 1990s, Goran Ivanisevic tried his luck at Wimbledon glory three times in 1992, 1994, and 1998 but lost on all three occasions in the final. By the time the 2001 Wimbledon Championships were around the corner, the Croat was out of the top 100 of the ATP rankings and could not earn an automatic berth in the main draw. However, he was awarded a wildcard to the tournament due to his past performances.

After a routine win in the first round, Ivanisevic defeated 1998 French Open champ Carlos Moya in the second round before beating a young Andy Roddick in Round 3. The Croat reached his first Grand Slam quarter-final in three years after defeating former US Open runner-up Greg Rusedski in the fourth round.

In the quarter-finals, he beat 4th seed Marat Safin to set up an encounter with 6th seed Tim Henman in the semis. Ivanisevic won the first set but Henman won the second set and bageled him in the third set.

After rain halted play twice, Ivanisevic eventually won the match to reach the final where he would face last year’s runner-up Patrick Rafter.

The final was an intense one with both players winning alternate sets as the match went into a deciding set. The final set went to sudden death and after failing to convert a few match points, Ivanisevic finally got his moment at Big W. He remains to be the only man to have won a Grand Slam as a wildcard.

#8 Gaston Gaudio, 2004 French Open

Gaston Gaudio came back from two sets down to win the 2004 French Open

Argentine Gaston Gaudio entered the 2004 French Open ranked 44th in the world and began his tournament by defeating fellow Argentine and son of the last Argentine male Grand Slam winner Guillermo Canas in a thrilling five-setter.

He followed this up with another five-set win over former World No.5 and 14th seed Jiri Novak. He then defeated 1999 Australian Open runner-up Thomas Enqvist in the third round in four sets before registering his first straight sets win of the tournament over Russian Igor Andreev to enter the quarter-finals.

In the quarters, Gaudio defeated three-time French Open champion Gustavo Kuerten in four sets following which, he beat compatriot David Nalbandian in the semi-finals in straight sets to set up the first and till date, the only all-Argentine Grand Slam final against Guillermo Coria.

Coria thrashed Gaudio in the first two sets 6-0, 6-3 and was looking to finally conquer his French Open title but Gaudio fought back and won the next three sets to win the match but not before saving match points. This win brought Gaudio into the Top 10 of the ATP rankings.
