Having a championship point at Roland Garros without winning the title is something that Jannik Sinner experienced earlier this year.

Sinner had three championship points against Carlos Alcaraz in the Roland Garros final that he lost in five sets.

This defeat was crushing for the Italian, with Sinner needing time to get over his heartbreaking defeat in Paris.

Sinner is now a four-time Grand Slam champion after winning Wimbledon, but another ATP player who experienced something similar was never able to recover.

Guillermo Coria was one of the big favourites for the Roland Garros title as the third seed in 2004.

The Argentinian was coming into the Paris major that year in impressive form, having won the Monte Carlo Masters and reached the final of the Hamburg Masters in the weeks leading up to Roland Garros.

Coria continued this form into Roland Garros, where he reached his first Grand Slam final by dropping just one set.

In the final, Coria would play an unlikely opponent in the 2004 Roland Garros final in his Argentine compatriot Gaston Gaudio, who was unseeded.

Gaudio had never reached a Grand Slam quarterfinal before Roland Garros in 2004, leaving Coria as the big favourite to win the title.

This was especially prevalent, as Coria had won three of his four previous matches against Gaudio, all of which were on clay.

The expected outcome of the match appeared to be playing out, as Coria dropped just three games to take a two-set-to-love lead.

Despite Coria leading the third set 4-4 40-0, Gaudio started to make a comeback and won the third and fourth sets to take it to a decider.

Coria would regain authority in this fifth set, taking a 4-2 lead, and looked to be on his way to an elusive Grand Slam title.

The then 22-year-old served for the match on two occasions, and had two championship points at 6-5 40-15, but Coria could just not get over the line.

After hitting the ball wide on those two championship points, Gaudio would fight back to beat Coria, 0-6 3-6 6-4 6-1 8-6.

In his press conference after the match, an emotional Coria suggested that nerves got the better of him.

“I think I was thinking too much at that stage,” Coria said after the match. “There was one very long rally at 40-15. I was thinking that if I had won that point, I could have won the match. He won the game, unfortunately for me.

“Then I was under pressure. I was thinking too much. What happened, happened. I have no words to describe it.”

Coria was the first man to lose a Grand Slam singles final in the Open Era after having championship points, with there now three players who have lost a major final from match point up.

What happened to Guillermo Coria after the 2004 Roland Garros final?

The other two players who lost Grand Slam finals after having a championship point are Roger Federer and Sinner.

However, both Federer and Sinner have won multiple major titles, while Coria took a big decline after this heartbreaking loss.

While Coria would still enjoy some positive results after Roland Garros in 2004, he would never reach a Grand Slam semifinal ever again.

The Argentinian only won one more title in his career at the Croatia Open in 2005, and only made two more appearances at Roland Garros.

After struggling with injury, Coria only played at Roland Garros again in 2005 and 2008, losing in the fourth round and first round, respectively.

Coria suffered a dramatic fall down the rankings after playing just two matches in 2007, and was never able to return to form in his comeback from a shoulder injury.

At just 27 years old, Coria would retire from tennis in April, 2009, and would never win a Grand Slam title despite having two championship points to do so.

Although Guillermo Coria no longer plays on the ATP Tour, his younger brother Federico Coria has been an active player since 2010 and has a career-high ranking of world number 49.
