The Latest from the PGA Championship at Whistling Straits (all times local):
Rory McIlroy and Jordan Spieth are on the course to start their second round at the PGA Championship on Friday.
Both players opened with routine pars and are 1 under for the tournament. They are five shots behind Dustin Johnson and David Lingmerth, who began his round with a birdie to get to 6 under. Johnson tees off later in the day.
Seven players are at 4 under. All play in the afternoon, except Scott Piercy. He joined Lingmerth as the only other player to break 70 in an afternoon round Thursday at Whistling Straits.
