Roland Garros semifinalist Lois Boisson breaks into Top 50 after first WTA title in Hamburg

In May, Lois Boisson wasn't even in the Top 500.

Today, she’s a Top 50 player.

The 22-year-old Frenchwoman continues her meteoric rise up the WTA rankings this week, jumping from No. 63 to No. 44, her Top 50 debut, after winning the first WTA title of her career in Hamburg.

Boisson's rapid rise is almost unprecedented. She only played her first tour-level main draw in Rouen, France in April, reaching the second round, and was ranked No. 513 in May. But she moved into the Top 400 by winning an ITF event, and then—in just her second tour-level main draw—she made a historic run to the semifinals of Roland Garros. As a No. 361-ranked wild card, she beat Top 10 players Jessica Pegula and Mirra Andreeva to become the first female wild card to reach the semis there in the Open Era.

After that magical run, she soared from No. 361 to No. 65.

Hamburg was just the third tour-level main draw of her career.

Already the French women’s No. 1 since her Roland Garros run, she’s now the first Frenchwoman to be ranked in the Top 50 since the very first week of 2025, when former No. 4 Caroline Garcia—who has since retired from professional tennis—was ranked No. 48.

The winner of the other WTA event this past week in Iasi, Romania—Irina-Camelia Begu—also makes a big leap today, rising from No. 110 to No. 82. Begu, a former world No. 22, captured the sixth WTA title of her career at the clay-court stop, and her first on home soil.

The winners of the three ATP events last week also make notable moves today: Denis Shapovalov returns to the Top 30 after winning in Los Cabos, rising from No. 33 to No. 28; Alexander Bublik also returns to the Top 30 after winning in Gstaad, rising from No. 34 to No. 30; and Luciano Darderi bounces back into the Top 50 after his run to the title in Bastad, rising from No. 55 to No. 46.

And Ben Shelton continues his steady climb up the upper echelon of the ATP rankings, rising from No. 9 to a new career-high of No. 8. Though he didn’t play any events last week, the American moves up after Holger Rune dips from No. 8 to No. 9 after not defending the points he earned in the same week last season with his run to the quarterfinals of Hamburg (which moved to May this year).

There are now an impressive six American players in the Top 8 of the ATP and WTA rankings combined—two men (No. 4 Taylor Fritz and No. 8 Shelton) and four women (No. 2 Coco Gauff, No. 4 Pegula, No. 7 Amanda Anisimova and No. 8 Madison Keys).
