The second seed won 6-7 (6/8), 6-2, 7-6 (12/10), 7-6 (7/5), to join the top seed and title-holder in Sunday's final. The match had been held over from Friday because of rain with Roddick 6-5 up in the first set.

Federer defeated third seed Lleyton Hewitt of Australia 6-3, 6-4, 7-6 (7/4) on Friday before the rain came down.

Sunday's final will be a golden chance for revenge for Roddick who has lost to Federer at the last two Wimbledons - in the semi-finals two years ago and in last year's final.

But the Swiss star holds an 8-1 winning record over the American, including the last four encounters between the two players.

"It was tough - we both played at such a high level. I was giving it everything I had," said Roddick.

"I definitely got lucky in the fourth set tie-break with that ball that trickled over. Credit to him - he played great and I am lucky to get through. I am ecstatic to be playing Roger again. I want to give it another go."

Roddick had endured two tough five-setters to reach the last four and he was stretched to the limit at times against Johansson, the 2002 Australian champion who is back to his best after major knee surgery.

Serves had dominated in the 11 games that were played in the tie on Friday before the rain fell and so it continued on the resumption as Johansson forced the tie-break.

Both players boomed out big serves in a bid to get the early advantage but it was Johansson who moved ahead when Roddick squandered two set points and then overhit a forehand on the first set point to the 30-year-old Swede.

Roddick took a quick lavatory break and that appeared to do him a power of good as he returned to break Johansson's serve twice in a row and jump out into a 4-0 second set lead.

The American was increasingly on the offensive hitting a high percentage of first serves and coming in to the net behind them. He took the set 6-2 to level the scores.
