PALM BEACH GARDENS, Fla. -- Branden Grace and Graham DeLaet share the lead after each carded 65s earlier in the day.
Defending champ Rory McIlroy? He's currently on the course and even par through his first 12 holes.
McIlroy, who recorded four rounds in the 60s on his way to winning here a year ago, hasn't gotten off to nearly as good of a start this year.
The Northern Irishman has already taken 21 putts through his first dozen holes and hasn't made anything over 5 feet so far.
His lone bogey of the day came on the par-4 sxith, where he missed the green from the right rough then missed his par putt from just outside 8 feet.
McIlroy bounced back three holes later, however, hitting his approach to 4 feet on the par-4 ninth before sinking the putt for birdie.
Meanwhile, Ben Kohles is among those making a move in the afternoon at 4 under through nine holes, while a number of others are 3 under.
