At 20, she is the youngest victor here since Iva Majoli upset Martina Hingis to take the title in 1997 while she is the first Latvian to win a Grand Slam singles title and she will rise from a ranking of 47 to 12 when the list is updated tomorrow. She is also just the second unseeded woman to win the French Open after Margaret Scriven in 1933, although her ranking will jump from 47 in the world to 12.
Ostapenko hit 54 winners, but it wasn't just the sheer number - it was also the timing.
Ostatapenko is the first Latvian to win a Grand Slam and not only did the president from her country call her after her semifinal win, but many of her peers were overflowing with praise for the new star in tennis.
"I didn't really understand how to play on grass and I was like, 'How can people play on grass?"
Ostapenko had never before won a tour-level title of any sort. Simona Halep's coach Darren Cahill, about Ostapenko.
From Halep's point of view her first time out of the gates at a Slam final, she was surrounded by an entourage of around 50 family and friends, and this time she kept it simple - and it nearly worked.
"I still can't believe I won", Ostapenko said in the post-match interview at Court Philippe Chatrier. She said: "I knew Simona is a great player and she was playing great".
Plus, one must marvel at her tenacity and ability to come from behind.
Her daughter has taken her by surprise by winning a grand slam so early in her career, but she recalled how it was a triumph 10 years in the making. I think I still can not believe it, because it was my dream and now it came true.
"All the credit for what you have done this tournament", Halep said to her opponent in the post-match ceremony. Keep it going because you are only a kid. Clay isn't even her strongest surface!
That's quite impressive.' Speaking about her future, Ostapenko said: 'I'm really happy, but I still have to improve some things and to get better as player. "So I want to really hit the ball [hard]".
JELENA Ostapenko has completed an extraordinary grand slam fairytale, upstaging Simona Halep to win the French Open. "She kept Halep waiting on the baseline for almost a minute as she rearranged her towels and her bag at the start of the match". "So if I can reduce them, I think it will be helpful". A win in Paris would also have handed her the top spot in women's tennis.
She conjured up three set points with a laser forehand down the line, forcing the match to a third set with another sweetly-struck victor. Hurts a lot, and I need time just to, I don't know.
