The Polish tennis star is through to the semifinals in Paris after beating 22nd-seeded Anna Kalinskaya of Russia 7–6, 6–3.
"Honestly, I don't know what's going on. Every match is a little crazy for me," says Chwalinska.
Chwalinska is only the second women's qualifier in Grand Slam history to reach the semifinals, where she will face either world number one Aryna Sabalenka or 25th seed Diana Shnaider.
