Dustin Johnson doesn't appear to be bothered by anything — not his close calls in the majors and not a bad memory from Whistling Straits five years ago.
He just keeps playing great golf.
Johnson burst out to the early lead Thursday in the PGA Championship with five birdies and an eagle. It added to a 6-under 66, giving him a two-shot lead among the early starters.
If it holds up for the rest of the day, it will be the fifth time in 13 rounds at the majors that Johnson had at least a share of the lead.
Those rounds have never been on Sunday, however, and that's what he is trying to fix.
Johnson says he worked hard the last three days to get his game in order.
