Timea Bacsinszky

Ostapenko, Halep in Paris final

Ostapenko celebrated her 20th birthday by crushing Bacsinszky's hopes with a nerve-jangling 7-6 (7-4) 3-6 6-3 victory, which included a total of 16 breaks of serve on a sweltering Court Philippe-Chatrier.

But her impressive tally of 50 winners, including a bludgeoning forehand on her second match point, helped her become the youngest finalist at any major since Caroline Wozniacki in New York eight years ago.
