Rory McIlroy has had to settle for a one-under-par opening round at the Memorial Tournament in Ohio after more tee trouble saw him drop a shot at the last.
Masters champion McIlroy is playing only his sixth regular PGA Tour event of the year at the tournament in Muirfield, which is hosted by 18-time major winner Jack Nicklaus.
The Northern Irishman, who tied for seventh place at last month's PGA Championship, continues to tailor his schedule to his personal circumstances – with focus soon turning towards the upcoming US Open at Shinnecock Hills, New York.
McIlroy had gone into the water at the third for a double bogey, but then responded with a run of three birdies to reach the turn at one under on Thursday (Friday AEST).
