Shane Lowry made a flawless start to his bid for a second Open title as Rory McIlroy effectively wrote off his chances of doing the same at Royal Troon.
Lowry carded five birdies in a bogey-free 66 that was only surpassed by England’s Daniel Brown, returning a brilliant 65 to claim a shock lead on his major debut.
Meanwhile, downbeat McIlroy had earlier dismissed his chances of mounting a challenge for a fifth major title after a costly run around the turn.
McIlroy was level par after seven holes before running up a double bogey on the signature par-three eighth, the Northern Irishman’s first attempt to escape a bunker on the Postage Stamp coming back to his feet.
