St Andrews: Irish amateur Paul Dunne stole the headlines at the British Open on Sunday, shooting a six-under 66 to go 12 under and move into the joint lead with South African Louis Oosthuizen and Jason Day of Australia.
Texan Jordan Spieth moved menacingly into position to strike for his third straight major, a first since Ben Hogan in 1953, and is one shot back after firing 66.
The 22-year-old Dunne from Greystones, a coastal town just south of Dublin, is the first amateur to be at the top of the leaderboard after three rounds since Bobby Jones in 1927.
Jones was also the last of only three players to win the Open as an amateur when he triumphed at Royal Liverpool in 1930.
Oosthuizen, who won at St Andrews in 2010, sunk a birdie putt on 18 to join Dunne, while Day missed an eight-footer for the outright lead at the last and is also on 12 under.
