The 2025 Rocket Mortgage Classic at Detroit Golf Club commenced with remarkable performances. South Africa’s Aldrich Potgieter and American Kevin Roy both shot a 10-under-par 62, setting a new course record.

Min Woo Lee also impressed, briefly tying the previous record before being surpassed. Mark Hubbard and Max Greyserman followed closely with nine-under rounds. Defending champion Cam Davis struggled, finishing at two-over, while Max Homa and Rickie Fowler ended at one-under, putting them at risk of missing the cut.

Collin Morikawa experienced putting issues, carding a three-under 69, and Patrick Cantlay and Wyndham Clark finished at six-under. Out of the 156-man field, 129 players ended round one under par, indicating a low cut line is expected.
