SCOTTSDALE, Ariz.

The par-3 16th hole is the centerpiece of the golf extravaganza known as the Waste Management Phoenix Open.

Unfortunately for the 20,000 fans who packed the rowdy stadium hole at TPC Scottsdale, the action was just getting started late Sunday afternoon when the final group moved on to the 17th tee.

That’s where Rickie Fowler self-destructed, first giving Hideki Matsuyama an unexpected chance in regulation, then handing the 23-year-old Japanese player the trophy on the fourth hole of a playoff.

Fowler blew a two-shot lead on the 317-yard 17th in regulation when his driver ran through the green and tumbled into the lake that wraps around the back and left side, with the ball traveling nearly 360 yards.

Using a 3-wood on the hole in the playoff, he pulled his drive left into the water just short of the green.

Matsuyama birdied the hole in regulation to tie for the lead, chipping to 2 1/2 feet. On the fourth extra hole, he chipped to 6 feet and two-putted for the win after Fowler missed a 10-foot par putt.

Fowler broke down in tears in the media center a few minutes later, overcome by emotion talking about his family.

Fowler forced the playoff with a 10-foot birdie putt on the par-4 18th after Matsuyama made an 18-footer. “The putt I made there was probably the best putt I have ever made in my life,” Matsuyama said.

The playoff was just as dramatic.

On the par-4 10th on the third extra hole, Fowler saved par with a 12-foot putt after driving into the left rough and skulling his approach long and right. Matsuyama made a 5-footer to extend the playoff.

They played the 18th hole twice to open overtime. On the first extra hole, Fowler chipped to a foot to set up a par after leaving his wedge approach short and right. Matsuyama rolled his 25-foot putt inside a foot. On the second playoff hole, Matsuyama topped Fowler’s 15-foot birdie putt with one of his own.

“Maybe from the outside it looked calm, but I was nervous inside,” Matsuyama said.

The crowd of 65,330 pushed the week total to a record 618,365, shattering the mark of 564,368 set last year. The event broke its own single-day golf record Saturday at 201,003 after drawing 160,415 on Friday.
