Dustin Johnson took advantage of the benign conditions to claim a one shot lead after the opening round of the PGA Championship.
The American was amongst the early starters at Whistling Straits, which allowed him to play some attacking golf golf to card a six under 66 for a one stroke lead over David Lingmerth.
Starting on the tenth, Johnson rolled in a 16 foot putt for his first birdie and backed it up with another on the eleventh. After a superb 3-wood into the par five 16th green, the world number eight drained a 27 footer for an eagle.
Johnson continued his fine form on the front nine, with back-to-back gains on the first and second. An errant tee shot on the par three third would leave a tricky lie in the lake-side bunker, leading to his only dropped shot of the day. Johnson would roll in a final birdie on the fourth.
"Today was pretty easy, I would have to say," the 31-year-old told europeantour.com.
"I was swinging well and I was hitting the shots where I was looking and I really felt like I was just super patient, stayed focused all day.
"I played pretty well at the US Open on the weekend. At the British Open I didn't play well on the weekend, but even the first two days I didn't feel like I was playing that good golf. I wasn't too comfortable with my swing. I wasn't hitting the shots that I wanted to hit. I didn't feel like I was too much in control.
"Today, I really felt like I had my ball under control a lot like I did at the US Open. We'll just have to see what happens. It's only the first round, we've still got a lot of golf to play."
