MARANA, Ariz --This was a battle of two of the PGA TOUR's resident bombers, but Jason Day was ready to take advantage of Bubba Watson's struggles on the greens.
Day's win was his second blowout of the week. He never trailed in the match after winning three of the first six holes with two birdies and a par to go 2 up.
Watson birdied the seventh to cut into the Aussie's lead but Day responded with a two-putt birdie from 43 feet at the par-5 eighth and went 3 up at the turn when his opponent bogeyed the ninth.
Watson and Day traded wins with birdies at the 12th and 13th. But Watson got into trouble in the desert at the driveable par-4 15th and eventually conceded the hole to end the match.
Day advances to the Accenture Match Play Championship quarterfinals for the second time in three tries at this event.
"It was just really steady golf," Day said. "Bubba gave me a couple early on and I just tried to hold that lead, and I tried to extend it. I think I was 4 under through 14 holes, so overall very, very happy with how I played. Like I said before, it was just steady."
SCORECARD STATS: Day made six birdies and nine pars in 15 holes. Watson had 11 pars, three birdies and a bogey.
HOLES WON: Day won seven holes. Watson won three holes.
NEXT UP: Day faces Graeme McDowell, who defeated Shane Lowry 3 and 2.
