Milos Raonic upsets Wimbledon champion Andy Murray, moves on to the Indian Wells quarterfinals

INDIAN WELLS, Calif. – Milos Raonic kept his head when all around him – that means you, Andy Murray – were losing theirs.

For the third time in four career meetings, Raonic defeated the reigning Wimbledon champion. This time, he came back from a set down, and a service break in the third set to run away with a 4-6, 7-5, 6-3 victory at the BNP Paribas Open that puts him into the quarterfinals.

As it happens, it was the 20^th anniversary of the day Dusan and Vesna Raonic and their three children, including three-year-old Milos, immigrated to Canada.

“I don't think there are really many matches that I've come back from a break down in the deciding set, or in the second set after being a set down,” said Raonic, whose next opponent will be the quirky, tricky Alexandr Dolgopolov of Ukraine.

“How much better I'm playing than I played in my first round is a big difference,” said Raonic, who is competing in his first tournament since the Australian Open in January because of a tendon injury in his left ankle. That first match, against the Frenchman Edouard Roger-Vasselin, came down to a third-set tiebreak.

There were only a few moments, when the unforced errors were piling up a little, that Raonic gave those patented angry looks to his support team – the ones where you wonder, “does he think it’s their fault?”

His opponent, on the other hand, was in full-fledged Murray mode Wednesday.

There was the constant grabbing of the left hip. There was also, of course, the searing string of objectionable profanity that left nearby ears ringing and probably traumatized one particular ball girl for the rest of the tournament.

But mostly, there was one terrible set – the third, and most important set of the match.

“First-serve percentage dropped. Missed a lot of backhands. Missed a few easy forehand passes, as well,” Murray said. “Today was fine until I went ahead in the third set, and then I was poor.

“I was just really disappointed with how the last 15 minutes of the match went,” he added.

Raonic admitted he did get away with a few.

“I think there was mistakes that (Murray) made that he wouldn't have liked to make. But also, the same happened from my side in the game I got broken.” Raonic said. “I think his mistakes were critical that he made them in that first break I got. But then I felt like I sort of picked it up for the rest of the set.”

Raonic cleaned up the errors. He had terrific success at the net but it didn’t even seem as though he went there 33 times; there weren’t many difficult volleys needed, because he approached on such top-quality material.

He also served very, very well.

Raonic opened the match with serves around the 140-mph mark; he ended it the same way, ending up with 15 aces and just three double-faults.

He gave up only two break points in over two hours of play; it just happened that Murray converted both opportunities.

The 23-year-old Canadian had solid history against Murray, beating him two of the three times they’ve met so far – even on clay in Barcelona, which might go down as one of his better efforts.

The one Murray victory, though, was in a Grand Slam, at last year’s U.S. Open (a tournament he went on to win). This won’t make up for that one. But for a first effort back, Raonic seems to not be missing a beat.

His next opponent, the only remaining player less than six feet at 5-foot-11, also serves big. The rest of Dolgopolov’s game, though, is rather more unpredictable.

But the Ukrainian is riding a wave. He upset a curiously off-form Rafael Nadal earlier in the tournament. And he easily dismissed the Italian Fabio Fognini, who has had a terrific 2014 so far, 6-2, 6-4 in an hour and 16 minutes Wednesday.
