Pakistan, June 5 -- Emma Raducanu's status as the only qualifier ever to win a grand slam title could be erased on Saturday by remarkable Polish outsider Maja Chwalinska.

The 24-year-old's 7-6 (4) 6-4 victory over Russian Diana Shnaider on Court Philippe Chatrier was her ninth in a row at Roland Garros, and set up a final clash with eighth seed Mirra Andreeva. Chwalinska, who is ranked 114th, arrived in Paris as one of 128 players just hoping to make it through to the main draw and without ever having beaten a top-50 player. Now she has toppled four in a row as well as Olympic champion Zheng Qinwen, and will fully believe she can match Raducanu's fairytale run in New York five years ago.

The Pole produced her best performance yet to see...
