Lee Westwood, Rory McIlroy and Henrik Stenson were among the pace setters during round one of the USPGA Championship.
Rory McIlroy fights back to shoot five-under-par, despite double bogeying the 10th and bogeying the 11th during USPGA Championship Round One at Valhalla Golf Club.
Lee Westwood leads the field after shooting an impressive six-under 65, despite starting with a double bogey.
Kevin Chappell joins the Englishman on six-under thanks to a round of six birdies and no bogeys.
Ryan Palmer is also in a tie for the lead after coming home in five-under-par, after he went out one-under.
Man in form Jim Furyk heads the challengers one shot back, shooting a five-under 66, thanks chiefly to a four-under-par front nine.
Henrik Stenson joined the Furyk and McIlroy group on five-under, just one back from Westwood's lead, thanks to a 16-foot birdie putt on the 18th.
One man with a lot of work to do is Tiger Woods, whose opening round of 74 leaves him nine back from the leaders, and in need of a good second round just to make the cut.
