Overnight, Philippoussis defeated French 13th seed Sebastien Grosjean 7-6 (7-3), 6-3, 6-3 in just 1hour and 56 minutes.
The 26-year-old from Melbourne spent almost three months in a wheelchair two seasons ago, missing the 2001 season and almost half of last season.
Having endured these setbacks, he was philosophical about his win.
“I was just thinking one match at a time. That’s the only thing I was thinking about. There’s no way I was thinking about the second week or the next weekend or anything like that. I was just thinking about going out there and playing good, solid grass court tennis and you know, obviously, when the serve percentage is high, it makes life a lot easier.”
Philippoussis, who wore several plasters with Greek words on his fingers during the match, says his heritage is an important part of his life, both within and outside tennis.
“It’s very important, you know, my Dad being Greek, Mum’s Italian. My mum speaks Greek. I was born in Australia, obviously I’m always going to be playing for Australia, but the Greek heritage is very important to me, because Greek was my first language growing up as a kid.”
Federer progressed to the final after defeating American fourth seed Andy Roddick 7-6, 6-3, 6-3.
Meanwhile, Australia’s Todd Woodbridge will compete in the Men’s doubles final, alongside Sweden’s Jonas Bjorkman.
They will meet Mahesh Bhupathi from India and Max Mirnyi from Belarus.
And, Woodbridge has also progressed to the semi-finals in the mixed doubles, as has fellow Australian Jordan Kerr.
