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, who led the Tour in earnings from the week after The Players Championship until Scottie Scheffler won last week’s Memorial, trails Scheffler by $580,357. He can regain the lead with a finish of solo third or better ($676,200).

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.
