Rory McIlroy struggled while current leader J.B. Holmes dismantled the WGC-Cadillac Championship at Trump National Doral on Thursday. His 10-under first round tied the tournament record for the course and put him four shots clear of the PGA Tour field.
While many players seemed to spend more time in the water hazards than on the fairways of Miami's aptly named Blue Monster, Holmes and Ryan Moore (who finished the day six under in second place) seemed almost infallible.
The pair broke out to an early lead and never looked back. Holmes registered eight birdies and one eagle. Moore stayed close with eight birdies of his own and suffered only one bogey on the unforgiving 18th.
With three rounds still to play, it isn't a runaway yet. However, if Holmes continues to back up his belief that the course is "too easy for a World Golf Championship" with his stellar play, then the Round 1 leader may very well take the title in stride.
