Dustin Johnson made a strong start on his return to Whistling Straits as he took advantage of an early tee time to lead at the US PGA Championship, writes the BBC.

The American, who was given a two-stroke penalty with victory in his sights at the same course in 2010, shot a first-round 66 for six under par. Swede David Lingmerth briefly matched Johnson's score but ended the day on five under as the wind strengthened.

Late starters Rory McIlroy and Jordan Spieth finished on one under par. Four-time champion Tiger Woods carded a 75 as he struggled to three over, and he faces a challenge to make the cut on Friday.

McIlroy, the world number one, was playing his first tournament since June after recovering from a ruptured ankle ligament.

The Northern Irishman was in a group with this year's major winners - Masters and US Open champion Spieth and Open champion Zach Johnson - and all three had to work hard in testing conditions.

Among the early starters, Englishmen Justin Rose and James Morrison both carded 69s to end the day on three under par, along with Denmark's Thomas Bjorn, with England's Paul Casey a shot back on two under.
