PARIS -- No. 41 Guillermo Garcia-Lopez came up with the upset of the tournament so far, stunning No. 3 Stanislas Wawrinka with a 6-4, 5-7, 6-2, 6-0 win in the first round of the French Open.

Wawrinka was off his game from the start, firing a whopping 62 unforced errors to 37 winners over the course of the two-hour-and-23-minute match; the Spaniard played much cleaner tennis, hitting 23 winners to 28 unforced errors.

"The match wasn't good at all. I was trying to find my game, trying to find to be aggressive, trying to find anything, and I didn't," said Wawrinka. "It's a big disappointment for sure. I'm really sad with that loss, but cannot change. I have to accept. I have to see what was wrong, to see what I want to change, the way I want to do it, and now think about the future and not about that match anymore, because I can't change the result."

Wawrinka is the highest seed to lose in the first round of the French Open since Andy Roddick in 2007, and the first Australian Open champion to lose in the first round of the subsequent French Open since Petr Korda in 1998.

The Swiss undoubtedly came into the tournament feeling the pressure after a banner start to the season in which he took down Rafael Nadal to win the Australian Open and beat Roger Federer in Monte Carlo to earn his first ATP Masters 1000 victory.

But his year has ebbed and flowed in between those signature triumphs. After winning in Melbourne, he failed to make it past the fourth round in both Indian Wells and Miami. After bouncing back to win Monte Carlo, he won just one match before the start of the French Open, losing in his opening round of the Madrid Open to Dominic Thiem and in the third round of the Italian Open to Tommy Haas.

"Before the match and during the match, it was not really about only the pressure. I think it's just a different story," said Wawrinka. "Now it's a different picture for my career. I need to put the puzzle back together, but differently than in the past, because now after winning Grand Slam, Masters 1000, being No. 3 in the world, everything is different and I still didn't find all the pieces."

Wawrinka's loss opens up the draw for a number of players, including Andy Murray, Fabio Fognini, Richard Gasquet and Gael Monfils -- though the latter two are dealing with injury woes. Garcia-Lopez will play Adrian Mannarino in the second round.
