INDIAN WELLS, United States (AFP) - French Open champion Stan Wawrinka was ousted in the fourth round at Indian Wells on Wednesday, losing in three sets 6-3, 5-7, 7-6 (7/5) to 15th seed David Goffin.
Swiss Wawrinka had his serve broken seven times after dropping his serve just once in his previous two matches in Indian Wells, one of the biggest events on the ATP Tour calendar outside of the four Grand Slams.
There were 13 total service breaks in the two hour, 25 minute marathon match.
"Two times I came back in the match but he came again. In general he deserved to win," said Wawrinka.
Goffin advances to the quarter-finals of the joint ATP and WTA Tour event where he will face Marin Cilic who defeated France's Richard Gasquet 7-5, 5-7, 6-2 in another three set thriller.
Wawrinka, who is ranked fourth in the world, blasted six aces but had five double faults and won just 43 per cent of his second serves.
Goffin's victory snaps a 14-match losing streak for the Belgian against top 10 opponents. His last win over a top 10 player was against No. 9 Milos Raonic in 2014 at the Basel tournament.
Taking the court later in the day is Rafael Nadal, world number one Novak Djokovic and Japanese star Kei Nishikori.
World No. 1 Serena Williams plays her quarter-final match against defending champion Simona Halep in the evening session.
Third seed Agnieszka Radwanska faces Petra Kvitova in the other women's quarter-final.
