MARANA, Ariz. -- Webb Simpson needed 18 holes to finally put away Gonzalo Fernandez-Castano, who nearly erased a 4-down deficit on the back nine.
Simpson was already 4 up after 11 holes in this match that started on the back nine. But the Spaniard launched a comeback -- winning the third hole when Simpson made bogey and the fifth and eighth with birdies to send the match to one last hole.
Simpson needed to halve to win, and he two-putted for par as Fernandez-Castano took three on the way to a bogey. This is just Simpson's second apperance at Dove Mountain, and it's the first time he's advanced past the first round.
"I played great for the most part," Simpson said. "I just kind of played super sloppy coming in. I made a couple birdies, but I just played sloppy.
"So for me I'm going to really dwell on my first nine holes and just try to keep playing well. Can't make those mistakes out here."
SCORECARD STATS: Simpson made five birdies, 11 pars and three bogeys and a double-bgoey. Fernandez-Castano made five birdies, 10 pars and three bogeys.
HOLES WON: Simpson won six holes. Fernandez-Castano won four holes.
NEXT UP: Simpson plays Hunter Mahan, who beat Martin Kaymer 5 and 4.
