Rotterdam - Frenchman Gilles Simon ended a 12-match loss streak to Andy Murray as he dumped the top seed out in the quarter-finals of the ATP event on Friday.
The persistent challenger stood 1-12 against the two-time Grand Slam winner and unleashed one of his best performances to stage the 6-4, 6-2 upset.
Murray, who went down double breaks at the start of each set, confessed to getting off to a poor start; the recent Australian Open finalist admitting he never found the rhythm to recover.
Fights to end
"I struggled with most shots and I had a poor start," said the world number four who won the Dutch title in 2009.
"I felt like it was tough hitting the ball in the slower conditions.
"My timing was well off. Simon is a top, top player who has been around the top 20 for most of his career. None of the matches I've won against him have been easy. He fights to the end and likes to extend the rallies.
"That's his game. I didn't feel tired but I certainly did not start well. I was not hitting the ball well from the back of the court and I made a lot of mistakes in the rallies."
Simon will take a 6-3 record into his semi-final with defending champion Tomas Berdych, who scraped his knuckles during a second-set fall on court on the way to a defeat of Gael Monfils 6-1, 6-4.
Simon said: "I've lost so many times to Murray that I'm not afraid at all.
"I know his game so well, there are no surprises. I knew what to expect and so did he.
"It was hard for me at the end to close it out, but the win was really worth it.
"Playing him gets easier every time that I do it. I'm happy that I was successful today (on Friday). Against Berdych I hope to continue just like this."
Berdych has now reached his third ATP semi-final of the season after posting his fourth win from five meetings with quirky French player Monfils, a former world number seven now ranked 21st.
