Known universally as A.P., the Northern Irish jump jockey broke all the records in his sport by the time he retired in April 2015.
He rode in more than 16,000 races, had 4,357 winners, over 1,000 falls and was champion jockey 19 times - every year he rode professionally.
He rode many times for owner JP McManus, who is also playing. Plays most of his golf at Sunningdale, this is his sixth appearance.
Says his best golfing moment was playing with Tiger Woods at the J.P.McManus Pro-Am in 2010.
Once overturned a golf buggy with fellow jockeys Mick Fitzgerald and John Francome in it.
