In late June, we introduced four new Titleist iron models to the worldwide professional tours as part of our performance validation process. The response on Tour to the new AP1, AP2, CB and MB (712 series) irons has been overwhelmingly positive, with many of our Titleist Brand Ambassadors putting the irons straight in the bag after initial testing.

Nick Watney (AP2), Chris Kirk (CB) and Scott Stallings (AP2) have each won on Tour since putting the new irons in play – performance validation at its best.

Given the buzz surrounding the new product introduction on Tour, we have received many comments and questions about differences between the new and previous generation Titleist irons. In an effort to address some of these questions, we’d like to take you “under the hood” of the new AP irons to illustrate how our most Advanced Performance technology to date is poised to help the games of serious golfers.

The new AP irons (712 Series) feature advanced multi-material designs that provide the high performance ball flight, stability, looks, feel and sound preferred by serious golfers. The new designs have been improved with internal weighting that utilizes a higher density tungsten material in order to distribute mass more efficiently. Redistributing the weight in this manner increases the moment of inertia (MOI) of the club without increasing the blade length. This means the new AP irons are more forgiving yet do not lose any workability or shot control.  The higher MOI designs of both the new AP1 and AP2 irons produce more consistent balls speeds over a larger area of the face, leading to better distance control.

Chris McGinley, Vice President of Marketing for Titleist Golf Clubs, says “good iron play is all about distance control. Increasing the MOI of the AP irons allows golfers to be more consistent with their irons shots, leading to more and better scoring opportunities."

“Traditionally, high MOI has been achieved by increasing the size of the club head,” adds Marni Ines, Director of Titleist Irons Development. “By concentrating weight in very specific locations with the high density tungsten, we can offer our most playable irons to date without sacrificing the workability that our target golfers demand.”

Fighting through high winds and heavy rains resulting from the remnants of Hurricane Irene, Brittany Lincicome trusted a Titleist Pro V1x golf ball to victory Sunday at the CN Canadian Open in Quebec.

Lincicome, 25, closed with a 2-under 70, getting her Pro V1x up-and-down for par on Hillsdale Golf & Country Club's par-4 18th to win by one shot and lead a three-win week for Titleist golf ball players around the globe, including Pro V1x loyalist Mark Calcavecchia's playoff-victory at the Boeing Classic.

Titleist golf ball players have now won 112 times across the worldwide professional tours in 2011, seven times the nearest competitor with 16 and more than all competitors combined.

Lincicome's winning pitch came from the downslope in front of the 18th green. Her Pro V1x golf ball landed soft on the soaked, slippery putting surface and took a few small hops before checking up and rolling to 3 1/2 feet from the hole.

 "The greens were pretty wet, so I decided it would kind of skip a little bit and then it was going to stop," she said.

"I hit it pretty good… I was trying to fly it 40 yards, and 40 yards of a lob wedge is not super easy. So it was great to get it up there close and not have too much pressure to tap it in."

Lincicome, who was recently selected to play for the U.S. Solheim Cup team, finished at 13-under 275 (68-68-69-70), finding the winner's circle for the second time in 2011. Fellow Pro V1x loyalist Stacy Lewis shot a final-round 5-under 67 and tied for second place at 12-under 276.

It's the first time Lincicome has won multiple LPGA tournaments in the same season.

"It was cool to finally check that off my list of things to do," said Lincicome, also a winner at the ShopRite Classic in June. "Beginning of the year was Solheim Cup, and then I locked that up, and then (the ShopRite Classic) and then now here. I've been very blessed this year, and hopefully it will keep going."

Lincicome was one of 116 players in the field that trusted a Titleist golf ball, more than nine times the nearest competitor with 12 and nearly three times all competitors combined.

CHAMPIONS TOUR: Pro V1x loyalist Mark Calcavecchia earned his first Champions Tour title with a playoff victory at the Boeing Classic.

 Calcavecchia birdied his final three holes in regulation Sunday at TPC Snoqualmie Ridge in Seattle to get into a playoff with Pro V1 loyalist Russ Cochran, who last month won the U.S. Senior Open. Cochran made his way into the extra session with a 12-foot eagle putt on 18.

Both players closed with 7-under 65s to finish the three rounds at 14-under 202.

On the first hole of the playoff, Calcavecchia two-putted for birdie and the victory.

"I think this will help me down the road," he told

Video: How Did You Get to the Playoffs?

There are many roads that lead to the PGA Tour's FedEx Cup Playoffs, as the saying (sort of) goes.

Team Titleist, for example, hopped on Interstate 95 toward New Jersey, relying on our trusty GPS navigation system to eventually guide us into the parking lot at Plainfield Country Club earlier this week.

Of course, Titleist Brand Ambassadors Gary Woodland, Brendan Steele, Scott Stallings and Kevin Na took different routes to The Barclays, made up of mostly of great golf swings, hard work and trust in their Titleist equipment.

Check out their stories in the video above.

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.

Check it out in the above video.

The driving range at Plainfield Country Club was jam-packed Tuesday, as players prepared for the start of The Barclays and the PGA Tour's FedEx Cup Playoffs.

Several Titleist Brand Ambassadors (such as Rickie Fowler, pictured below) also got their first look at the new Prototype Titleist Vokey Design SM4 wedges, which are making their PGA Tour debut this week.

Check out all of Team Titleist's pictures from Tuesday's practice round in the slideshow below.
