What it means: Spieth birdied two of the first three holes and never gave anyone much hope of catching him. When the Texan birdied the par-5 15th, he became the first player in Masters history to reach 19 under par. He bogeyed 18 to miss out on breaking Woods' Masters scoring record, but at 21 years, eight months and 17 days, Spieth is the second youngest Masters champion, just a few months older than Woods was when he won his first green jacket in 1997. He is just the fifth wire-to-wire Masters champion, joining Raymond Floyd (1976), Jack Nicklaus (1972), Arnold Palmer (1960) and Craig Wood (1941). With his second win of the season, and his sixth top-10, Spieth is projected to move to No. 2 in the world rankings.
Round of the day: McIlroy and Matsuyama both birdied 18 to shoot bogey-free 66s. World No. 1 McIlroy rallied Friday to make the cut, then went 10 under par on the weekend to grab fourth place. Matsuyama recorded his third career top-10 in a major.
Biggest disappointment: Charley Hoffman started the day at 10 under par and had an outside chance to catch Spieth, but he bogeyed the first hole and never recovered, finishing with a 2-over 74 and a share of ninth place. As a consolation prize, he'll be heading back to Augusta next year.
Shot of the day: Mickelson flashed his short-game magic several times in the final round, highlighted by holing his third shot from a greenside bunker at the par-5 15th for eagle.
