Andy Murray knocked out in Wimbledon quarters

He was nicknamed "Baby Fed," when his coach at the time said Gregor Dimitrov was more advanced at his age than Roger Federer. It was difficult label with which to live, but suddenly at age 23 Dimitrov has become the tennis player that he was predicted to be.

He put an exclamation point on his potential Wednesday when he stunned defending champion Andy Murray in their Wimbledon quarterfinal, 6-1, 7-6 (4), 6-2.

He won at Queens, on grass, less than two weeks ago, making him the only male player with victories this year on all three surfaces.

The Bulgarian, best known as Maria Sharapova's boyfriend, vaulted into the semifinals to face the No. 1 seed and 2011 winner Novak Djokovic, who won his quarter from Marin Cilic, 6-1, 3-6, 6-7 (4), 6-2, 6-2.

Seven-time Wimbledon champ Roger Federer will face Milos Raonic in the other semi Friday. Federer defeated Stan Wawrinka, his fellow Swiss, 3-6, 7-6 (5), 6-4, 6-4.

Raonic, who along with Eugenie Bouchard in the women's draw, gives Canada two semifinalists. He hammered Aussie teenager Nick Kyrgios, the man who ousted Rafael Nadal, 6-7 (4), 6-2, 6-4, 7-6 (4).

It was a harrowing 24 hours on Centre Court for former champions, Nadal and Sharapova beaten on Tuesday, then Murray, who in 2013 became the first British male in 77 years to win singles, getting stunned. And that was with the Duke and Duchess of Cambridge, William and Kate, cheering from the Royal Box.

"He was the better player from start to finish," Murray said of Dimitrov. In his previous four matches, Murray had not dropped a set.

"Today was a bad day," he said. "I made mistakes, unforced errors. And then I started going for too much and taking chances that weren't really there. Sometimes you just have to take it on the chin and move on."

Dimitrov didn't like the "Baby Fed" nickname given to him by onetime coach Peter Lundgren. "At first I thought it was funny," he said recently, "But then it became boring. People still are talking about it."

Now they'll be talking about his win over Murray. "I was positive," Dimitrov said. "I was ready. I had a lot of patience. It's something I worked for, to get on that stage."

On Tuesday, Kyrgios, the 19-year-old Aussie, was on that stage and upset Nadal. But a day later he couldn't handle Raonic. "I was struggling halfway through the second set," Kyrgios said. "He served unbelievable. He was in such a rhythm. I couldn't do anything."

Federer was delighted with his win, having lost in the second round last year. "I was really disappointed," he said. "Wimbledon is one of my goals."

In two women's quarters. Bouchard won, 6-3, 6-4, over Angelique Kerber, who had upset Sharapova, and Simona Halep beat Sabine Lisicki, 6-4. 6-0.
