Rory McIlroy believes he is facing a "near impossible" task of landing the Green Jacket at Augusta after just making the cut.
The two-time major winner had a frustrating second day on with the putter as he saw numerous failed birdie putts and went on the score a disappointing 77, 5-over par.
He sank a four-foot putt for par on the 18th to ensure that McIlroy will be playing the final two days but will be first to tee off alongside a marker.
"I got a really massive wind switch on four [his tee shot flew the green and almost hit Adam Scott on the fifth tee] and then hitting the sprinkler on 13 to go up into the azaleas.
"I felt like I played well coming in. I gave myself looks at birdie almost every hole. I couldn't get one to drop."
McIlroy began day two in contention at one-under but after dropping four shots on the back nine sits eleven shots off the pace.
The world number nine also admits he was unaware of the importance of his final shot during Friday's session.
"I didn't know that putt on the last was to make the cut, but when I got into the scoring area and saw that I was in (joint) 46th place, it was a bit of a sigh of relief that I'm here for the weekend," he said.
The Northern-Irishman realises the difficulty of the task if he is to make up the eleven shots he trails leader Bubba Watson by.
"I just want to go out there and try to get off to a fast start. Eleven shots back (of leader Bubba Watson) with two rounds to play is going to be nearly impossible to make up so I'm trying to shoot two really low rounds and see where that puts me at the end of the week.
"It will take something phenomenal to shoot something in the mid-60s and get myself back under par going into the last day. But I'm going to need to be two, three or four under par going into the last day to have any sort of chance."
