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.

Rory McIlroy carded a woeful eight-over-par 78 as he missed the cut at the Canadian Open. It is the first time the Northern Irishman has failed to make the weekend in a tournament since the Open Championship last July.

Rory McIlroy made an 8 on his fifth hole Friday at TPC Toronto, free-falling down the RBC Canadian Open leaderboard on his way to a missed cut. McIlroy followed that quadruple-bogey debacle with four bogeys and a double in shooting 8-over 78.

Rory McIlroy admitted Wednesday that he was “pissed off” that his name had leaked after what was supposed to be confidential driver testing ahead of the PGA Championship.

It was a strange week for McIlroy, who arrived at the PGA as the most celebrated player in golf after he completed the career Grand Slam.
