Over the last few years, Titleist Brand Ambassador Kevin Na, equipped with his Scotty Cameron Studio Select Newport Tour model putter and Pro V1x golf ball, has consistently proven himself as one of the best putters on the PGA Tour.

He is ranked in the top 10 in many of the PGA Tour's putting statistics, including the new Strokes Gained stat, which shows how many strokes are gained or lost due to putting over the course of the season.

Kevin is also currently No. 2 in Total One-Putts (578), One-Putts Per Round (8.03) and One-Putt Percentage (44.6%), behind only Titleist Brand Ambassador Steve Stricker in each category.

Team Titleist caught up with Kevin earlier this week at The Barclays to talk about his putting prowess, which he credits to keeping a consistent tempo.

At this week's U.S. Amateur Championship at Erin Hills in Wisconsin, Titleist is once again the overwhelming #1 choice of many of the game's best amateur golfers.

Of the 315 players in the field, 252 are relying on Titleist Pro V1 and Pro V1x golf balls for their success, more than 10 times the nearest competitor with 24 and four times all competitors combined.

With Titleist golf ball players making up 80 percent of the field at the U.S. Amateur, Titleist is also the tee-to-green favorite across every major golf club category.

From drivers, fairway metals and hybrids, to iron sets, wedges and putters, no less than 41 percent of the field in any major equipment category are placing their trust in the superior performance and consistency of Titleist equipment at one of the most prestigious events in amateur golf.
