Victoria Mboko completed the best two weeks of her career by winning her first WTA Tour-level title at the National Bank Open in Montreal. Mboko made history, beating four Grand Slam champions, including top seed Coco Gauff in the third and Naomi Osaka in Thursday’s final.

Mboko is the first Canadian in history to win an NBO singles title in Montreal. She’s just the third Canadian champ overall of the WTA Tour 1000 event in the Open era (since 1968). The same teenager was playing at a tiny event in Croatia one year ago and lost in the first round to a player currently not even in the top 800.
