Mcllroy exits from Canadian Open, Champ takes vital 2-shot lead

Masters champion Rory Mcllroy tumbled out of the RBC Canadian Open on Friday with his worst round in nearly a year, with Cameron Champ taking a two-stroke lead into the weekend in the final event before the US Open.

Mcllroy shot an 8-over 78, making a mess of the fifth hole with a quadruple-bogey 8 in his highest score since also shooting 78 last year in the first round of the British Open. He had a double bogey on No. II, four bogeys and two birdies.

"Of course it concerns me," Mcllroy said. "You don’t want to shoot high scores like the one I did today. Still, I felt like I came here obviously with a new driver thinking that that sort of was going to be good and solve some of the problems off the tee, but it didn't."

At 9 over, the two-time Canadian Open winner was 21 strokes behind Champ on the rain-softened North Course at TPC Toronto at Osprey Valley.
