Rory McIlroy, who leads the PGA Championship after two rounds, will tee off Saturday afternoon looking to put more space between himself and his nearest rivals, which include American Jim Furyk and Australia's Jason Day.
The Northern Irishman, winner of the British Open earlier this summer, stands at 9-under, just one stroke ahead of Furyk and Day, who fired a 6-under on Friday - tied for the lowest round of the tournament - to surge up the leaderboard.
Americans Rickie Fowler and Phil Mickelson, who are currently at 7-under and 6-under, respectively, are two other big names who will be looking to make noise on moving day at the Valhalla Golf Club in Louisville.
Spain's Sergio Garcia, meanwhile, was far off the pace at even par at the start of Saturday, saying in remarks to Efe that he was having trouble reading the greens.
But he has played his best golf of the tournament through 14 holes on Saturday, tallying five birdies and no bogeys to move to 5-under for the tournament, just four shots behind McIlroy.
American 14-time major champion Tiger Woods, who has been struggling with a back injury, missed the cut. EFE
