By his own estimation, Nicholas Mason rolled in close to “a hundred feet in putts” on Monday.

The last 25 gave the Leilehua and UH Hilo graduate a Thursday tee time in the Sony Open in Hawaii.

Although he “didn’t have it” for much of his round at Hoakalei Country Club, Mason leaned on his putter to earn a spot in a five-way playoff for two of the four Sony Open berths available in the qualifier.

After signing for a 4-under 68 in regulation, Mason’s 25-foot birdie putt on the first playoff hole — Hoakalei’s 450-yard par-4 17th — earned him a third appearance in the Sony Open at Waialae Country Club.

“I didn’t have my ball-striking, but my putter just did not let me down all day,” Mason said. “It was unbelievable.

“I just hung in there. I knew it would be a struggle because I hadn’t been hitting the ball that good and I just wanted a chance. I got into a playoff and hit another bomb.”

Luke List arrived at the course as the field’s second alternate, but played his way into his fourth event of the PGA Tour season with a 7-under 65. Nick Killpack followed at 66 and five players finished at 68. Mason and Byron Meth, a University of the Pacific graduate, then birdied the playoff hole to claim the final two berths in the first full-field event of 2016.

Mason, 33, splits his year between Ewa Beach and Denver and will represent Hoakalei in the Sony Open. He joins Moanalua senior Shawn Lu, Kahului’s Garrett Okamura and Punahou graduate Parker McLachlin as local entrants in the field.

He qualified for the Sony Open in 2010 and 2012 and missed the cut. He’s since played in the 2014 U.S. Open and won his second Hawaii State Open last month.

“I think I’m a better player now, and I’m more experienced,” Mason said. “Before when I played the Sony it was nerves. I was young, didn’t know what I was doing. Now I know what to expect. I just need to hit the ball a little better and putt the same.”

The Monday qualifier moved to Hoakalei this season after a lengthy stay at Turtle Bay’s Palmer Course, giving Mason a chance to play his way into the field on his home course. Mason said he thought his familiarity in the tradewinds would give him an edge, but there was only a hint of a breeze for most of the day.

“But still, knowing the greens is huge out here,” Mason said. “I don’t ever play them this fast, but (course superintendent) Les (Jeremiah) did a great job.”

List booked his ticket to Honolulu as an alternate, unsure of whether he’d be in the Sony Open field. He left no doubt Monday with a round of eight birdies and a 32 on the front nine.

List ranks fourth in driving distance on the Web.com Tour with a 316.7-yard average, but doesn’t plan on taking his driver out of his bag much at Waialae.

“So that’s fine. I like all courses that put a premium on getting the ball in the fairway, and I think Waialae is a very good second-shot golf course,” said List, who played in the 2013 Sony Open. “All of your second shots, you have to really have your numbers down and I’ve been hitting my irons pretty well, so I’m looking forward to the challenge of just going out there and seeing if I can make some putts out on those greens.”

Meth will make his professional debut this week after a college career that included a West Coast Conference title and the U.S. Amateur Public Links Championship in 2014 to earn a spot in The Masters last year.

“I knew if I hit one in there tight it would put a lot of pressure on the other guys, and I was fortunate to have a perfect number and hit a nice high 6 iron in there to about 8 feet,” Meth said of his approach on the playoff hole. “I love match play, so it was kind of right in my zone.”
