Woods struggles as Montgomerie rockets into lead

"I had hit that putt a bunch in practice, and the first couple times I stroked it, I missed it 2 feet left or low and 3 or 4 feet short," Mickelson said. "I ended up playing about 8 or 10 feet of break and it swung right in there."

That was one of the few thrills on this day at Winged Foot.

Ernie Els saved a pedestrian round of 4-over by holing out from the ninth fairway for eagle and a 74.
