What it means: It was the second win in as many weeks for Spieth, who won the Australian Open by six shots last week. At age 21, Spieth became the youngest champion in the 16-year history of this event. Tiger Woods won in 2001 at age 25.
Round of the day: Starting the final round with a seven-shot lead, Spieth kept the pedal to the metal throughout. Spieth's only hiccup was a double bogey at No. 14, but he immediately followed that with a birdie at 15.
Best of the rest: Day matched Spieth's 6-under 66, a round that was fueled by four straight birdies, on Nos. 11-14.
Biggest disappointment: Can you really have a disappointment in a hit-and-giggle event? Certainly Tiger Woods was disappointed with the way he chipped, chunking several over the course of the week (and he was joined in that category by Bubba Watson on Sunday). But overall Woods, who finished with a 72 that included a triple-bogey 8, had to be happy with his game.
