McIlroy and Khan three off USPGA lead

England’s Simon Khan, winner of one PGA Championship already this season, was the joint leader in another far, far bigger one in Wisconsin last night - until he bogeyed the last three holes of his second round at the USPGA Championship.

The 38-year-old had to cram 29 holes – more than any other player in contention - into a day that began with another long fog delay, so mental fatigue may well have had something to do with his disappointing finish on the demanding Whistling Straits course.
