Rory McIlroy reflected on a frustrating week after a closing 69 left him on level par for the Masters.
The Northern Irishman's second round of 77 left him on the cut line but a strong finish took him almost into the top-10.
Four birdies in five holes around the turn saw him make a move through the field but he found Rae's Creek with his approach to the par-five 13th and then took another six at the long 15th.
He rectified that with another birdie at the next but all-in-all it left McIlroy ruing his mistakes.
"I sort of got it going a little bit round the turn...13 is where it de-railed me a little bit," he said. "I only had a nine-iron into the green, hit a good shot straight at it but it came up short.
"All of a sudden you turn that into a four and 15 into a four, that's four shots and you think of the shots I've left out there this week...
"I'm going to look back at what might have been, the signs are there that my game is there from tee to green, if I can just convert some of the chances I'm giving myself my season looks like it could be a really good one."
