France, July 21 -- French Open semi-finalist Lois Boisson entered the world's top 50 for the first time on Monday after winning the biggest title of her fledgling career at the Hamburg Open.

The 22-year-old Frenchwoman beat the defending champion Anna Bondar from Hungary 7-5, 6-3 to brandish the trophy after five matches on the clay courts at the Am Rothenbaum stadium.

"It's really tough to win a tournament, so when we did it, I'm really happy with that," Boisson said. "Just happy, and I hope it will continue like this."

In the WTA world rankings published on Monday, Boisson will sit at 44th on the ladder. Just before the French Open in Paris in May, she languished at 361.
