Northern Irishman Rory McIlroy turned a potential eagle chance into a five-putt double bogey, as he dropped down the leaderboard at the Pebble Beach Pro-Am in California, Sky Sports report.

McIlroy started day two four shots off the lead, however, despite almost making the green on the par-four fifth, managed to double bogey the hole which was the catalyst to his disappointing round of 74.

Current world number one Dustin Johnson fired a seven-under 64 to move into a share of the lead at the halfway stage at 12 under.

Fellow American Beau Hossler followed up his opening round of 65 with a 67 to share the lead with Johnson, with McIlroy 11 shots off the pace heading into the weekend.

McIlroy’s playing partner and crowd favourite Phil Mickelson, is three shots off the lead after an impressive 65 on day two.

England’s Paul Casey is coping better than McIlroy however, currently sitting on seven under after two rounds in California.
