The Masters takes place at Augusta National Golf Club, Georgia USA this week with Danny Willett defending his title. Lee was joint second with Justin Spieth last year.
Lee has had some good finishes in the Masters, 2nd in 2010, T3rd in 2012, T8th in 2013 and 7th in 2014.
He had a 13.19 (19.19 UK) tee-time on Thursday with Shane Lowry and Sergio Garcia. Playing in very blustery conditions, Lee was 3-over at the turn but fought back with 5 birdies in his final six holes to end his day 2-under par and in sole third place.
"...it was nice to make five birdies in a row. Really got some momentum going. Got me back in the Tournament", he said.
Lee made the cut set at +6 when he was 5-over for the day and 3 over for the event. Four players tie for the top on 4 under par.
Lee had a 13.10 start with Mark Leishman on Saturday. Lee was 1 under after the front nine and kept the bogeys off his card on the back nine. After birdying three of his last six holes, he finished 1 -under for the event and in T9th position.
"I did what I needed to do today", he said. "I needed to get into the red. Obviously I would like to be deep in the red, but one under is pretty good. I've got half a chance tomorrow if I can get a roll going on the front nine. I hit the ball pretty well, the short game was pretty good and I holed a few putts, so it was nice. With less wind it was more scoreable, but the tougher flags come out, the greens get firmer and get quicker so it's swings and roundabouts really. I feel I left a few out there on the front nine. I felt like I could have shot 65 quite easily".
He went out with Thomas Pieters at 14.05 (20.05 UK) and was 1-under for the outward nine, but three bogeys on the back nine saw him finish 1 -over for the event and in T18th place.
The day ended in an exciting sudden death finish which was won by Sergio Garcia, who becomes the 2017 Masters Champion.
