Andy Murray falls to Grigor Dimitrov at Wimbledon

The upsets keep rolling at Wimbledon, as Andy Murray, the defending champion here, fell to Grigor Dimitrov on Wednesday on Centre Court.

Murray, who became a legend in Great Britain when he raised his arms on this same court a year ago, had been playing absolutely incredible tennis heading into this quarterfinal match, rolling through his first four matches without dropping a set, and alongside Novak Djokovic, was the favorite to win this tournament in just a few days.

But Dimitrov, a 23-year-old star in the making, said he sensed something off about Murray's game in the warmups before the match began.

"As soon as we started warming up I sensed his game wasn't at the highest level," Dimitrov told the BBC after the match. "The first set really helped me get into a good rhythm, and I just held my ground."

The first set Dimitrov is talking about was a 6-1 streamrolling of the defending champion, who was attempting to make it to his sixth straight semifinal at Wimbledon.

But it wasn't meant to be for Murray, who had a shot in the second-set tiebreaker to get things back level. But Dimitrov's game never dipped, and after winning the tiebreaker to take a two-sets-to-none lead, it looked all but over for Murray, who looked confused and frustrated on Centre Court for most of the match.

Dimitrov broke Murray's serve five times, and while the win had a lot to do with the way Dimitrov was able to hit the ball cleanly, Murray's 37 unforced errors was the glaring stat that led to this upset.

For Murray it's a fourth straight disappointment at a Grand Slam, and a fourth straight major without making a final. Before the 2013 U.S. Open, Murray had made four straight finals, but his game just seemed lackadaisical on Wednesday and the opponents this late in the second week are too good not to take advantage.

Murray joins the growing list of big stars who have been upset this year at Wimbledon, with Rafael Nadal, Serena Williams, Li Na and Maria Sharapova all exiting earlier than expected.
