PITTSFORD, N.Y. -- Canadian journeyman David Hearn is the clubhouse leader at the PGA Championship after shooting a 4-under 66.
Hearn, who has never won on the PGA Tour, opened and closed his round with bogeys. Otherwise, he took advantage of an Oak Hill course softened by overnight rain, ripping off six birdies.
Robert Garrigus and England's Paul Casey are one shot back after 67s.
Jim Furyk is the leader on the course at 5 under with four holes to play.
Tiger Woods got off to a solid start in his bid to win a 15th major title, making the turn with a 2-under 33 before a bogey at the par-5 fourth hole knocked him back.
The 34-year-old Hearn lost in a playoff at the John Deere Classic just before the British Open.
