The New Zealand golfer Danny Lee has made a solid start to the US PGA Championship in New Jersey.
Lee fired an opening round one under par that has him four shots off the lead held by American Jimmy Walker.
He's in a tie for 21st.
Walker shrugged off some recent struggles to shoot a five-under-par 65 and a one shot lead at the Baltusrol Golf Club.
Walker, who has missed four cuts in his last eight events including the U.S. Open and British Open, found his form at the year's last major.
"I just haven't been scoring, I haven't been making the 15, 18-footers you need to make to start running up the leaderboard," said Walker who won three times in 2014 and twice last year but has just three top-10s from 19 events this season.
Tied for second are Englishman Ross Fisher, Argentinian Eliliano Grillo and German Martin Kaymer.
World number one Jason Day is three off the lead.
Day's playing partners Rory McIlroy and Phil Mickelson did not fare so well.
Twice PGA winner McIlroy struggled with his putting and shot a four-over 74 without a single birdie.
Phil Mickelson, who won the 2005 PGA Championship at Baltusrol, was also four-over after a bogey on his 11th hole but revived with three birdies in a five-hole stretch from his 12th to card a 71.
Jordan Spieth fired an even round 70.
