Tim Henman suffered a disappointing semi-final defeat to Lleyton Hewitt at Queen's Club having led by a break in the final set.
Hewitt will go for his fourth Queen's title in Sunday's final
Henman had looked on course for his first win over Hewitt on grass in four attempts when he recovered from a poor first set to hit top form.
The Briton led 2-0 in the third set but Hewitt came back to win 6-3 3-6 6-2.
Hewitt will face James Blake in the final after he beat defending champion Andy Roddick in the second semi-final.
Henman had just levelled the match and was a break up in the third set when he reacted angrily after a poor call cost him his serve at 2-1.
He later called the supervisor on to the court to complain and lost his concentration, allowing three-times former champion Hewitt to win five games on the trot and take victory.
Henman said: "Sometimes you handle things well, sometimes you don't. I don't think I did handle it particularly well today.
"The line calling was appalling today. There were probably seven or eight calls that were just mistakes.
"It's very difficult to play like that when you sort of lose all confidence."
Hewitt was clearly relieved with his win.
He said: "It was always going to be a tough match - I'm just happy to get through.
"You keep battling away, but Tim was playing well. I was just waiting for my chances and took them in the third set.
"There were so many tight line calls and they can't get it right every time."
Blake's win over Roddick was his first in seven attempts. He out hit his compatriot from the baseline to record a 7-5 6-4 victory.
