"This is my favorite tournament with the galleries, here and the Open Championship", Spieth said.
"I'm very pleased with the second round of this Masters and we're in a position now where we, I think, can go out there and win this thing, and certainly make a run", he said.
Spieth made up six strokes after starting the day trailing leader Charley Hoffman by 10 shots.
"I was a bit surprised at how loud the cheer was when my ball landed about 35 feet away from the hole", Spieth would say afterward about his performance at the hole, where he two-putted for par.
The 2015 Masters champion acknowledged afterward he was too aggressive as he settled over an approach shot at the par-5 hole with 98 yards left to the flag.
"Instead, I was stuck in the "15's a birdie hole" mentality and it kind of bit me a little bit".
Jordan Spieth posted another quadruple bogey at the Masters yesterday, carding a nine on the par-five 15 hole.
And, to make matters even worse, this isn't the first time such pain has been inflicted upon Spieth by the demanding Augusta National layout.
No matter, the exorcism was complete. and at that point, Spieth was shooting par on the day.
Danny Willett and Rory McIlroy left trailing in Charley Hoffman's wake
Pieters had threatened to set a daunting target when he raced to the turn in 32 and also birdied the 10th to reach five under par. Meanwhile, defending champion Danny Willett began the second round with a snowman, taking an 8 on the opening hole.
"And now three over, I feel like I need to snag something tomorrow". "But do it through patience and taking advantage of the par 3s".
Since then he has shot 74-73-73-75. It was his worst score at the Masters.
But on Thursday - in extremely hard conditions - Spieth had a bit of a struggle with an opening 3-over 75. Spieth's putt for a double-bogey 7 hit something on the green, bouncing up and leaving an 8-footer for triple bogey, which he missed.
As Spieth walked from the 18th green toward the clubhouse, his father, Shawn, put his hand on his son's shoulder, then patted him on the back and spoke into his ear.
"It was a really good day today at Augusta National", said Spieth, who shot 3-under 69 to break a string of four over-par rounds at Augusta.
And, minutes earlier, with a huge gallery and large media contingent closely watching, Spieth cleared a potential mental hurdle by making par on No. 12.
Spieth actually made it through the disastrous 12th hole that ended his 2016 Masters Title quest with a par on Thursday. "It was tough - tough today because you don't know exactly what the wind is going to do to the ball".
"Mr. Palmer sent letters each time after I won and they were always special", Spieth said.
"My low one is lower than everyone else's, so I can actually kill someone at head-high", Fitzpatrick said.
