Rory McIlroy hailed his latest fast start in a major - in what he describes as the 'fiddliest' Open he has ever played.
McIlroy, the 2014 champion at Hoylake, would love to make history by becoming a two-time Open winner on the occasion of the 150th championship.
"It's the fiddliest Open that I've played. It's the only way I can really describe it," said the Ulsterman, after shooting a six-under par 66 on the Old Course to trail early pace-setter Cameron Young by two shots.
