PGA Tour rookie and Titleist Brand Ambassador Brooks Koepka made his 2015 debut last week at the Waste Management Phoenix Open.

And he's off to a great start.

Putting the new Titleist Pro V1x golf ball in play for the first time in competition, Koepka closed with sizzling rounds of 64-66 for a 15-under-par 269 total and his first PGA Tour victory. He hit every green in regulation on TPC Scottsdale's back nine during the weekend.

 "I got a chance to practice with the new ball a lot while I was home the last couple of months and I feel really confident. The tipping point for me is its performance from 60 yards and in and its softer feel than the previous generation. The length off my metals and long irons is similar, but I love the reaction I get from it on my scoring shots, so I am looking forward to playing it under the gun," said Koepka earlier in the week.

And when it was on the line yesterday, Koepka held up under the pressure to make a pivotal eagle on the 15th hole to earn a share of the lead and he never looked back. After the win, Koepka had a chance to quickly reflect on his path to victory early in his young career.

"I'm just finding my way right now, and, you know, everything is in the right track. I've got a good team behind me. We're working hard."

Koepka posted six Top 25's in 16 PGA Tour events last year. In his first two events of the 2014-15 PGA Tour season, he finished T8 at the Frys.com Open and T4 at the Shriners Hospitals for Children Open. Koepka, who was named European Tour Rookie of the Year last year, captured the Turkish Airlines Open in November, the first time he put the new Titleist 915 driver into play.  

"I played a lot of golf last year and I was tired by the time the European Tour season was over. I was able to relax at home, and play and practice for the last couple of months and now I am ready to get the season going again. I got off to a good start in the fall and hope to continue performing that way. I want to be prepared every week I tee it up."

Welcome to the PGA Tour winner's circle, Brooks!

Some of the best players in the world have gathered in Scottsdale, Arizona for the Waste Management Phoenix Open. Featuring large, passionate crowds and very low scores, the WM Phoenix Open provides some of the most exciting tournament action all year. 

First time participant and Titleist Brand Ambassador Jordan Spieth is looking forward to the chance to play in front of over 100,000 fans who will attend the event each day.

"Yeah, it's a cool atmosphere. It's unlike any other FedEx Cup event. It's been a lot of fun the last couple of days."

Players will not only have to impress the large crowds, they will also have to face a redesigned layout, featuring new greens and a more difficult finishing hole.

"I like the looks of the redesign. The course is a little bit more demanding and the 18th hole is more visually intimidating. Overall I'm excited about everything," said Titleist Pro V1x Loyalist Rickie Fowler. 

With a beautiful setting, energized fans and a lot of birdies already posted, the Waste Management Phoenix Open is sure to offer golf fans plenty of excitement.

Be sure to check out the slideshow above for an inside-the-ropes look at the action from earlier this week.

BY THE NUMBERS: 2015 WASTE MANAGEMENT PHOENIX OPEN

 This week at the Waste Management Phoenix Open, Titleist is the overwhelming golf ball of choice with 83 players in the field trusting a Pro V1 or Pro V1x golf ball for their success. That's more than 5 times the nearest competitor with 15.

Titleist was also the top choice in the approach, sand and lob wedge (131) category.

Senior Vice President of Titleist Golf Ball R&D Bill Morgan and Director of Product Implementation Matt Hogge take us on a behind-the-scenes look at the process and people behind the development of the new Pro V1 and Pro V1x golf balls. 

Before a golf ball can become a Titleist, it must live up to the highest of expectations. Before we can make a million, we must make one.

The 2015 Waste Management Phoenix Open features one of the strongest fields of any non-major this year. The Stadium Course at TPC Scottsdale is also coming off an extensive 7-month renovation project which has resulted in many veteran players adjusting how they attack the layout.

And to get an insiders view, Team Titleist caught up with Titleist Brand Ambassador Graham DeLaet this week to learn his keys to success to scoring well at TPC Scottsdale.

 DeLaet tied for second place at last year's event, after firing a 65-65 on the weekend. A native of Canada and a graduate of Boise State, DeLaet resides in Scottsdale and plays and practices at TPC Scottsdale periodically when he is not traveling.

"I think with the alterations that have been made to the course it favors the high ball hitter if anybody," said DeLaet.

"The greens have been playing hard and 'springy' this week. You have to bring the ball into the greens at a high angle and play it about six to eight yards short of where you want it to end up. Players seem to be getting a little bit higher and bigger bounce than usual when it hits these greens. That may change as the week progresses depending on the weather we are expected to get, but right now that is the way they are playing and how we are preparing."

Statistically, DeLaet is among the longest drivers of the ball with a 305.7 average (13th) and is in the top 10 in par 3 scoring average (2.88/5th) and par 5 scoring average (4.42/10th), strengths of his game that will surely come in handy this week.

"The new changes force you to have excellent course management and hit tee balls that will set you up for the best angle to approach the green. It is going to be a little more difficult to attack the pins early in the week with the way they are receiving the golf balls, but I think you will see some low scoring if and when they soften up. And, as always, whoever is putting best will be in the hunt, but it will crucial to put yourself in position to make those middle range putts."

Good luck to Graham and all of #TeamTitleist this week!
