After Scottie Scheffler's latest win at the Memorial Tournament, much of the talk coming into this week's RBC Canadian Open was how Rory McIlroy would respond in his first start since the PGA Championship.

McIlroy turned in 5-over 40 and then started his back nine in bogey-double-par-bogey. In danger of shooting in the 80s, he played his final four holes in 1 under. The 78 was McIlroy’s worst score since shooting the same number in the first round of last year’s Open Championship.

McIlroy, who won the 2019 and 2022 RBC Canadian Opens, did not have it this week. After opening with a 71, he shot 78 on Friday, his card showing a quad 8 on the par-4 fifth hole. He managed to only beat four guys this week.
