Unseeded Ostapenko, No. 3 Halep to meet in French Open final
Both players won semifinal match in 3 sets
Simona Halep has beaten No. 2 Karolina Pliskova to reach the French Open final, where she will face the unseeded Jelena Ostapenko.
Third-seeded Halep won 6-4, 3-6, 6-3, clinching the victory on the first of her two match points when Pliskova sent a return long.
Halep broke early in the third set and threatened to break again in the fifth game but Pliskova saved with an ace and went on to hold.
Pliskova then broke to level the set but Halep broke straight back to leave the Romanian serving for the match.
Unseeded Ostapenko makes history
Ostapenko became the first unseeded women's finalist at the French Open in more than 30 years by beating Timea Bacsinszky.
The 47th-ranked Ostapenko, the first Latvian player to reach a Grand Slam final, won 7-6 (4), 3-6, 6-3.
The last unseeded player to reach the final at Roland Garros was Mima Jausovec, who lost to seven-time French Open champion Chris Evert in 1983.
Ostapenko sealed the win on her second match point with a forehand winner to break Bacsinszky's serve for the fourth time in the set. It was her 50th winner of the match, which also saw her make 45 errors.
The Latvian turned 20 on Thursday and Marion Bartoli led the Court Philippe Chatrier crowd in singing "Happy Birthday," in French, to Ostapenko moments after her victory.

"I'm really happy," Ostapenko said. "I love to play here, I love you guys, you're amazing, thanks for coming to support me. I'm just happy with the way I celebrated my birthday."
Ostapenko is yet to win a World Tour title. The last player to win their debut title at Roland Garros was Gustavo Kuerten, who lifted the title the day the Latvian was born.
Ostapenko's strong forehand made the difference. It was measured at 76 m.p.h. (122 km/h), faster than the average of top-ranked men's player Andy Murray.
"I was always playing aggressive and trying to hit the ball when I have the chance," Ostapenko said. "It probably helped me to win today."
Thursday was also Bacsinszky's birthday, her 28th. It is the second time in three years she has lost in the French Open semifinals.
Bacsinszky received treatment on her right knee shortly after dropping serve in the seventh game of the contest. But that did not seem to trouble the Swiss player too much as she broke straight back.
Ostapenko had never been past the third round at a major until this week but she didn't let the occasion faze her as she took the first set on a tiebreaker.
Ostapenko then broke early in the second set but Bacsinszky won the last four games and levelled the match when her opponent double faulted.
Both players struggled on their serve in the final set, which had six of the 16 breaks in the match.
Ostapenko will face either second-seeded Karolina Pliskova of the Czech Republic or No. 3 Simona Halep of Romania in the final.
