Spieth became the first wire-to-wire winner at the Masters since Raymond Floyd in 1976, and this might have been even more special. Craig Woods in 1941 is the only other Masters champion who led by at least three shots from the opening round to the trophy presentation.
Phil Mickelson tried to make a run. So did Justin Rose. Neither got closer than three shots at any point, and it wasn't long before Spieth was making another birdie putt to take the drama out of the back nine.
Mickelson (69) and Rose (70) tied for second. It was the 10th time Mickelson has been runner-up in a major. Woods jarred his right wrist then he struck wood under the pine straw on the ninth hole. He recovered and closed with a 73, 13 shots behind.
Spieth won for the third time on the PGA Tour and fifth time worldwide. He will rise to No. 2 in the world, still a ways to go to catch McIlroy at the top. When McIlroy won back-to-back majors last year to establish himself as the game's best player, the quest was to find a rival.
Spieth answered that this week on perhaps the biggest stage in the sport with his record-setting week at Augusta.
