World number one Scottie Scheffler conjured up a brilliant 64 to lead the British Open after an enthralling second round as home favourite Rory McIlroy's roller-coaster ride continued at Royal Portrush on Friday.

Rory McIlroy shot 1-under 70 in the first round of the British Open at Royal Portrush that is also serving as a homecoming for the Northern Irish star.

Brian Harman took dead aim in a mild breeze and surprising sunshine Friday at Royal Portrush for a 6-under 64 that sent him into the weekend hunting another British Open title. He was called the “Butcher of Hoylake” when Harman won the claret jug at Royal Liverpool two years ago because the British press was fascinating by the Georgia native’s love for hunting.
