Spieth and Bubba Watson tied at -5 going into the final day.
Things started out great for the youngster. He hits this birdie putt on the second hole. Spiethtakes the lead at -6.
On three. Matt Kuchar would tie for the lead wiht an incredible chip shot.
But on the back nine things wouldn't go Spieth's way. As he takes a swim on twelve. Spieth bogeys the hole to drop to -5.
Which left it wide open for Bubba. Three stroke lead going onto the 18th. Nice on and would two put to win the Masters.
Watson takes the green jacket for the second time in three years.
Here's a look at the final standings. Watson finished at -8. Jordan Spieth and Jonas Blixt tied for second at -5.
"I don't remember the last few wholes. I just remember hanging on. I just kept thinking make pars, make pars. Somehow I did and walking up to 18 was a little bit easier this time. This time was different. The first time was for me it was almost like I lucked into it. This time was a lot of hard work, dedication and got back here," said Bubba Watson.
"Standing ovations for both of us to each green is a dream come true. I thought I fought hard and if I hit a couple puts a little firmer it could have been a different story but hats off to Bubba. When he is driving the ball well out here he is tough to beat," said Jordan Spieth.
