London: Britain's Tim Henman was seething after a run of questionable line calls helped Australian rival Lleyton Hewitt to a controversial 6-3, 3-6, 6-2 semi-final victory at Queen's club on Saturday.

"There's frustration," said the 76th-ranked Briton, three times a losing finalist at the west London tuneup event for Wimbledon.

"But I do feel very good and very confident about my game," he said.

The 31-year-old's optimism was severely tested as stood up a break 2-1 in the third set against the man who had beaten him in eight of nine previous meetings.

The Briton was mightily frustrated in the fourth game as a return which computer simulations showed had kissed the baseline was called out and he decision upheld by the umpire.

The decision denied Henman a 3-1 lead after saving two break points and put the scrappy Hewitt back into the contest, 2-2.

A fuming Henman committed his only two double-faults of the one hour, 45-minute contest on his next two service games to crash out.

"There are so many close ones, and people cant be right 100 percent of the time," said Hewitt, who has lost two finals this season and last won a title 18 months ago in Sydney.

"The linesman and the umpire thought it was out," he said.

Henman voiced a contrasting opinion as the majority of calls went against him on the day.

"The line calling was appalling today. Sometimes it's against you, sometimes for you," said the four-time semi-finalist at Wimbledon. But when there are as many bad calls as (today), it's going to have an impact," he said. "You just hope that, you know, it's gonna go in your favour on a big point. There was probably seven or eight calls (with) mistakes. It's very difficult to play when you lose all confidence," he said.

Hewitt will Sunday play the winner from fellow three-times champion Andy Roddick and fifth seed James Blake.

"I'm just happy to get through to another final at Queen's," said Hewitt, champion from 2000-2002.

"Tim was playing extremely well," he said.

Two of Hewitt's wins against the 76th-ranked British veteran came in the 2001 and 2002 finals in west London. The latter paved the way for Hewitt's trophy triumph at Wimbledon three weeks later.
