Federer, current king of the game who has won his last nine finals, 22 matches in a row and past three tournaments, did his part with a 4-6, 6-3, 6-2 victory over Swede Thomas Johansson.

Roddick, runner-up to the Swiss at the All England club a month ago, followed on as he polished a 3-0 career mark against German grinder Nicolas Kiefer, winning their semifinal 7-5, 6-3.

It was the second meeting between that pair after Roddick lifted the Indianapolis trophy last weekend over the 25th-ranked Kiefer.

Victory in one hour, 22 minutes was the longest of the week for Roddick and gave the defending champion a third victory against Kiefer.

"I'm excited to be through in final," said Roddick, winner of 18 straight on cement.

"It should be a great match, Roger and I look forward to playing each other We bring out the best in each other -- and I owe him one from Wimbledon."

The 21-year-old American, who is bidding to duplicate a torrid summer, 2003 run which led to four titles including the US Open, won his 38th match of the season on his preferred hardcourt surface, improving to 19-2 in Canada.

Kiefer put up a fight in the first set, forcing Roddick to save three break points in the fifth game.

The German salvaged two set points in the tenth game, levelling for 5-all before Roddick pounced.

Two games later, the American put Kiefer into a 0-30 hole, then managed to more set-winning chances. The German saved the first but netted a forehand to lose it.

The tide turned in the second set with Roddick running off with through a break in the sixth game.

Top seed Federer, is now a win away from claiming four trophies in succession.

That figure would by definition include three straight on three different surfaces, duplicating a mark last set by Bjorn Borg in 1979 who earned his own hat-trick on grass, clay and hard-court.

Federer now stands 56-4 this season, winning 30 of his last 31 with his last defeat coming against Gustavo Kuerten at Roland Garros.
