Rory McIlroy revealed the two issues with his all-round game that are concerning him ahead of next week’s US Open at Oakmont. McIlrory endured a week to forget north of the border at the Canadian Open, firing an eight-over-par second round to miss his first cut since the Open at Royal Troon last July.

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 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.
