McIlroy on a roll in Ohio

Rory McIlroy picked up seven birdies and two eagles to storm to the top of the leaderboard on the first day of Jack Nicklaus’ Memorial Tournament in Ohio.

But the Northern Irishman, who won the BMW PGA Championship on Sunday, might have been five strokes clear of the field had he not spoiled his remarkable run over the back nine with a double bogey on the par-four 14th hole.
