Spieth was two strokes clear after seven holes of his final round at Augusta last year, when victory would have made him the youngest Masters champion and the first debutant to win since 1979.
But successive bogeys saw the American drop behind eventual winner Bubba Watson, and he ended up three shots back in a tie for second with Jonas Blixt.
Now 21, Spieth goes into this year’s tournament on the back of victory at the Valspar Championship and back-to-back runners-up spots.
He said: “Last year I remember being in here saying I had no expectations, didn’t know what it was going to be like, never played the tournament before.
“This year, I come in maybe expecting to play well on a course I feel very??comfortable on. I feel like it suits my game nicely and also I feel like I’ve??been playing well.
“Having been so close last year and having a little experience and riding some??momentum, I hope to put myself in contention and use what I’ve learned since??last year.
“I think last year’s event, I certainly took a couple things out of it, as??well as the positives that came from closing out a couple of tournaments at the??end of the year and a few weeks ago.”
Reflecting on last year’s final round he said: “That was definitely the highest amount of pressure I’ve ever felt. That first tee shot, I think I hit it into the ninth fairway and was just real quick off the tee. Played pretty much the entire round feeling different than I’ve ever felt on the golf course.
“I enjoyed it, but at the same time when you’re feeling that kind of pressure,??it’s hard to get comfortable picking fearless shots, and then I kind of bailed??out on a couple of swings, trying to look up a little quickly.
“I guess the hardest lesson taken from last year was that I had an opportunity??to make a dream come true, and I had it in my hands, and then I was just a??little anxious.”
