It will take a miracle for McIlroy to win the Masters after day 2

The 2015 Masters is in danger of turning into a procession thanks to Jordan Spieth’s incredible opening 36 holes, while for Rory McIlroy, it will take the best performance of a glittering career to reel the American in from 12 shots back.

Things could have been even worse for McIlroy who had looked in danger of missing the cut at +3 through a mistake-littered front nine, only to come home in four-under-par, to leave himself on -2 for the tournament.

While the Ulsterman will take heart from the way he battled back at Augusta National, odds of 33/1 reveal the enormity of the task facing the four-time Major champion.

Off the back of a course-record score through 36 holes, Spieth is now odds on at 4/9 to convert his five-shot lead over fellow American Charlie Hoffman.

Hoffman was on course to finish on -10 until bogeying the last and although he’s shown expert composure up to now, there are other more familiar faces a few shots back who are perhaps fancied more than the 16/1 shot.

Spieth wasn’t the only one putting himself into the Masters record books as Dustin Johnson showed just why Augusta is a haven for big hitters.

The longest driver on the PGA Tour became the first player to card three eagles in one single round as he went onto finish as one of a trio of players on -7 and DJ is now second favourite to win a first major at 8/1.

Level with Johnson are two Englishman. Justin Rose has a fair crack at second Major having followed up his 67 by carding a 70 and blessed with an ice-cool temperament to suit the biggest occasions 14/1 looks plump.

Paul Casey’s brilliant comeback season continued as he added to an opening 69 with a 68 and at 16/1 is well in the hunt.

Two-time Masters champion Phil Mickelson reaffirmed his love affair with the Augusta layout as his usual mix of strong iron player and improvisation around the greens sees him at -6 and 16/1 for a third Green Jacket.

Tiger Woods improved his score to go two-under alongside McIlroy, but even though the American pointed to Greg Norman’s infamous midway meltdown in 1996, where he relinquished a six shot lead, 80/1 is about the right assessment of the 2005 champion’s chances.
