After wildly contrasting starts Tiger Woods and Phil Mickelson ended honours even in the opening round of the US PGA Championship in Chicago - but now they have some catching up to do.
The world number one and number two, going head-to-head in a major for only the third time, both returned three-under-par 69s at Medinah Country Club, as did playing partner Geoff Ogilvy.
But on a day of record low scoring in the event the trio majors, trail leaders Lucas Glover and Chris Riley by three.
Another American, Davis Love, threatened to be the story of the round when he turned in 30 and was seven under with two to play on the longest course in major history.
But Love, in need of a good week to earn a seventh successive Ryder Cup cap next month, triple-bogeyed the short 17th, going completely under his ball in the rough by the green and then hitting his next attempt into a bunker.
Luke Donald, wearing black in memory of Darren Clarke's wife, was in the group on 68 and Sergio Garcia was on the same four under mark until he three-putted the 16th - the hole where he played his stunning eyes-shut shot seven years ago when finishing runner-up to Woods.
Padraig Harrington and Graeme McDowell both shot first rounds of three-over-par.
