Canadian Teen Mboko Upsets Coco Gauff Montreal Quarterfinals

Coco Gauff has experienced notable serving struggles during the 2025 National Bank Open in Montreal, frequently committing a high number of double faults, including 23 in a three-set win over Danielle Collins. Despite these issues, Gauff has demonstrated remarkable mental resilience, rallying to win matches even when not playing at her best, as she acknowledged the need to improve her serve while remaining optimistic about her future performance. Renowned coach Rick Macci suggested that Gauff's second-serve problems could be corrected quickly with simple adjustments, emphasizing her elite mental game and potential to transform her serve into a weapon. In a recent upset, Canadian teenager Victoria Mboko defeated Gauff to reach the quarterfinals, highlighting the ongoing challenges Gauff faces on court. Meanwhile, alternative rankings like the Universal Tennis Rating have recognized Gauff's rising stature, with her victories over top players such as Aryna Sabalenka elevating her status as a leading figure in women's tennis. Despite Sabalenka's dominance in traditional rankings and tournament wins, Gauff's recent Grand Slam success and strong form have positioned her as a formidable competitor on the WTA circuit.
