Maja Chwalinska came through qualifying and brought a broom with her.
Zheng Qinwen got four games. Elise Mertens got four games. Both were handed second-set bagels. What began as a qualifier’s opening has turned into one of the sharpest raids of this Roland Garros draw.
Chwalinska’s 6-4, 6-0 win over Mertens was not just a follow-up to the Zheng shock. It was proof that the first result was not a loose brick falling from the sky.
The 24-year-old Pole backed up one major statement with another, removing the Belgian No. 1 and reaching the third round after having fought her way through qualifying.
Chwalinska Starts Like a Player Who Believes She Belongs
The first game told Mertens this would not be comfortable.
Chwalinska broke immediately, forcing her way into the match before the Belgian had settled. She then held for 2-0 and gave herself the early scoreboard control every qualifier dreams of against a seeded opponent.
Mertens did respond. She broke back, levelled at 2-2, and later moved ahead 4-3 after another break. For a moment, it looked as if experience might begin to pull the match back toward the Belgian.
But Chwalinska did not fold.
At 4-4, she broke again. Then, serving for the set at 5-4, she did not blink. She moved to 40-0, gave back one point, and closed the opener 6-4 on her second set point.

That was not a lucky set. It was a set full of breaks, tension and momentum swings, and Chwalinska came out of it with the cleaner head.
Mertens’ Calf Trouble Meets Chwalinska’s Momentum
The second set became brutal very quickly.
Chwalinska broke at once, held to love, then broke again for 3-0. Mertens called for a medical time-out and received treatment on her right calf, with Belgian reporting noting that something had already troubled her in that calf during practice the previous day.
That matters for the context, but it should not swallow the story.
Because Chwalinska still had to do what many players fail to do in that situation: keep her foot down. A wounded opponent can be dangerous in strange ways. Matches can become messy. Sympathy can interrupt focus. The player in front can start thinking about the finish too early.
Chwalinska did none of that.
She held through a long fourth game, broke again for 5-0, and then served it out. The final game briefly moved to 40-15 after she had held match points, but the direction of the match had long since been clear.
The second set was 6-0. Not just a win. A run-away.

Mertens Had the Winners but Chwalinska Had the Match
The numbers explain why this became so one-sided. Mertens hit more winners, 21 to 17, but she also sprayed 41 unforced errors. Chwalinska kept hers to 20. She landed 81 percent of her first serves, won 56 percent of return points, broke six times from nine chances and took 78 percent of the points on Mertens’ second serve.
That last number is the killer. Every Mertens second serve felt like an invitation.
Chwalinska also won 10 of 15 pressure points and finished with a dominance ratio of 1.40 to Mertens’ 0.71. Smaller ranking, bigger calm. Less noise, more control.
Chwalinska Is No Longer Just Passing Through
There is a point in every qualifier’s run where the language has to change.
At first, it is about reaching the main draw. Then it is about getting a win. Then, if the player keeps going, it becomes something else entirely.
Chwalinska has reached that point.
She has come through qualifying, beaten Zheng Qinwen 6-4, 6-0, then beaten Elise Mertens 6-4, 6-0. That is not background noise. That is a player forcing her name into the third round with increasing authority.
Roland Garros loves a story that starts outside the main gates.
Chwalinska has walked through them, looked around, and started removing established players from the room.
