Coco Gauff defeated Danielle Collins 7–5, 4–6, 7–6 in the first round of the WTA Masters 1000 event in Toronto on hard court, confirming her status as the pre-match favourite with odds of 1.33 to Collins's 3.61. The American top seed found herself tested across all three sets, surrendering the second set before recovering to edge a tight decider in the tiebreak. Gauff's victory in a competitive encounter demonstrates her ability to navigate close matches against a capable opponent, though the loss of the middle set suggested occasional lapses in consistency. The result keeps Gauff on course in her bid for title contention at one of the season's most prestigious hard-court events.
