Australia's Samantha Stosur will meet Francesca Schiavone of Italy in the women's singles final at the French Open in Paris on Saturday.
The pair advanced on Thursday in contrasting fashion.
Schiavone had just taken the first set against the fifth seed Elena Dementieva in a tiebreak when the Russian withdrew injured, while Stosur romped to a 6-1 6-2 win over Serb Jelena Jankovic.
While Schiavone has become the first Italian woman in the Open era to reach a grand slam singles decider, Dementieva's injury issues could force her to miss Wimbledon, which starts in London in a little over two weeks.
"I have a tear in my left calf so it's very painful to even walk," she told reporters.
"I got it after my second match so I just aggravated during this match. Today was just a sharp pain, a bit too much, I couldn't really move on the court."
Stosur also created some history for her country by becoming the first Australian woman into a grand slam final since Wendy Turnbull in 1980.
She needed just one hour to thrash fourth seed Jankovic.
Stosur, who put out four-times champion Justine Henin and world number one Serena Williams en route to the last four, sauntered to a comprehensive victory on Court Philippe Chatrier under clear blue sky and warm sunshine.
In a courtside interview, the Aussie declared herself ready to lift the famous trophy.
"Yeah, I think so. Why not?! Saturday will be no better day than any other one," she said.
"I've been playing well and I'm just looking forward to getting into it. If I can keep this form going, I think I've got a good shot."
