Johnson answers wake-up call

US Open champion Dustin Johnson sleep-walked through his first four holes before snapping to attention to fashion a one-under 71 and remain tied for the lead after the second round at the RBC Canadian Open yesterday morning (Singapore time).

Johnson, who shared the overnight lead with fellow American Luke List after an opening 66, had an early tee time.

He started at the 10th hole and bogeyed 11, double-bogeyed 12 and bogeyed the par-five 13th before turning on the jets to salvage his round.

"I just got in some tough spots," said Johnson, who finished the day on seven-under 137 to share the halfway lead with List at Glen Abbey outside of Toronto.

"I think I was still asleep the first four holes, but I finally woke up and played pretty well the rest of the day," the world No. 2 added.

List began another hot, dry day at the fast-running, dusty layout with a two quick birdies but ran into trouble on a trio of holes in the valley of the back nine, making three bogeys in four holes.

"I'm real happy the way I finished up," said List, who hauled himself back into a share of the lead with birdies at the par-five 16th and 18th.

The co-leaders held a one-shot lead over Spaniard Jon Rahm, American Kelly Kraft and Canadian amateur Jared du Toit, who all shot 71, the same score as the two leaders.

World No. 1 Jason Day, the defending champion, had trouble following up his opening 69 as he stumbled to a 76 that left him eight strokes back.
