Hi Chris,I take your point although I would say Opens at the Old Course have been won with 18 and 19 under par (Faldo and Tiger) Jordan Speiths 12 under is the lowest ever winning score in an Open at Birkdale,it's previously been won at -5 Watson -1 Miller and level par O Meara,that 62 albeit on the best scoring day was still a spectacular display of golf on one of the most challenging of Championship courses,when you've got the best major player ever in Jack Nicklaus tweeting congratulations and Gary Player doing the same,you know it was a moment in history.
