MARANA, Ariz -- This was a battle of two players who have a wealth of match play experience -- and each were trying to go to the Accenture Match Play finals for the second time. Kaymer was second to Luke Donald in 2011, and Mahan won in 2012.
This match was over almost before it started, though.
Kaymer went 2 down after just four holes after he failed to birdie either of the opening par-5s at Dove Mountain. Mahan birdied them both, then birdied three consecutive par 4s starting at No. 6 to take a 5-up lead. The match was over when both played parred the 14th.
Mahan has now won nine consecutive matches at Dove Mountain, dating back to 2011. Kaymer was the last player to beat the American, ousting Mahan 2 and 1 in the third round in 2011.
The last time Mahan trailed in a match was the sixth hole in the first round a year ago, a span of 133 holes.
"Well, it's strange, I've always gotten off to good starts and get some leads and been hitting it well," Mahan said. "If you hit fairways and greens, you know you're going to put pressure on your guy. It's definitely nice to get a lead and that's the goal for everybody, but to do it, it's a good feeling for sure."
SCORECARD STATS: Mahan made six birdies and seven pars in 14 holes. Kaymer had 1 birdie, 1 eagle and 12 pars.
HOLES WON: Mahan won six holes. Kaymer won one hole.
NEXT UP: Mahan plays Webb Simpson, who beat Gonzalo Fernandez-Castano 2 up.
