Rory McIlroy faced a significant setback at the RBC Canadian Open, finishing near the bottom of the leaderboard and missing the cut by 12 strokes after a woeful second round. His performance, which included a quadruple bogey and a lackluster score of 78, has raised concerns about his preparation for the upcoming U.S. Open. McIlroy, who switched to a new driver ahead of the tournament, expressed deep worries about his current form. Cameron Champ currently leads the event, significantly ahead of McIlroy, who is left questioning his game leading into a major championship.
