Steve Stricker went to the turn in a truly brilliant 30 and on six under par with five to play had the chance to shoot the lowest round in Major history at the US PGA Championship.
The American Ryder Cup star's birdies included the 15th and 18th, two of the three that Tiger Woods double-bogeyed, and he led by three from fellow America Jerry Kelly and Swede Alex Noren, already twice a winner this season.
And 18 year old Matteo Manassero, on his debut in the event, shot a two under 68 that meant he outscored Sunday's WGC-Bridgestone Invitational winner Adam Scott by one.
World Number One Luke Donald, despite his double bogey at the 15th, was one under with two to go and that was good enough for a share of eighth with, among others, compatriot Brian Davis.
Phil Mickelson was one further back, recovering well from the shock of three-putting from only three feet on his opening green.
Ian Poulter was on the same mark after 14, while Ross Fisher dropped from four under to one over on his return to action after missing last week's event as a result of his baby son Harry being taken into hospital during the Irish Open.
Rory McIlroy, Lee Westwood and Darren Clarke were all among the later starters.
Stricker added a four on the long fifth and needed only one more birdie for the magical first Major 62.
