INDIAN WELLS >> David Goffin upset Stan Wawrinka 6-3, 5-7, 7-6 (5) to reach the quarterfinals of the BNP Paribas Open on Wednesday, ending the Belgian's 14-match skid against top 10-ranked opponents.
Goffin advanced to the quarterfinals, where he next plays No. 10 seed Marin Cilic, who beat No. 8 Richard Gasquet, 7-5, 5-7, 6-2 as temperatures reached 91 degrees (32 C) under cloudless skies in the California desert.
Wawrinka and Gasquet weren't the only higher seeded men to lose. No. 12 Milos Raonic defeated No. 6 Tomas Berdych 6-4, 7-6 (7).
"I was struggling with my serve and it was difficult with the heat," Goffin said. "In the third, it's tough to fight again with the heat and with the level of Stan. The tiebreaker is like you flip a coin."
Novak Djokovic, Rafael Nadal and Serena Williams were to play later matches.
Ranked 18th in the world, Goffin improved to 2-26 against top-10 players, having beaten No. 9 Milos Raonic in the quarterfinals at Basel in 2014. The 25-year-old Belgian has gone to three sets in each of his matches so far. He saved two match points to beat wild card Frances Tiafoe in the second round and then rallied from a set down to outlast Guido Pella in the third round.
In women's quarterfinals, No. 3 seed Agnieszka Radwanska defeated Petra Kvitova 6-2, 7-6 (3).
Ranked ninth and winner of two titles already this year, Wawrinka struggled mightily in the 2 1/2-hour match that featured 13 service breaks, with Wawrinka dropping serve in seven games.
In the third set tiebreaker, Wawrinka held at 5-all and was serving when he badly played a smash off Goffin's short ball, sending the ball well past the baseline. Goffin served out the match, winning on the next point when Wawrinka netted a forehand. Wawrinka had won all three of their previous matches.
"Was a match without brain, let's put it that way," Wawrinka said. "If you want to win matches, you need to stay focused, even if you had break up in the second or in the third."
