Phil Mickelson came within a whisker of shooting a 59 on Thursday in the first round of the Waste Management Phoenix Open, a score even more impressive because it was the first competitive round he played with a new Callaway RAZR Fit Xtreme driver in his bag.
Mickelson carded 11 birdies to no bogeys in his 60, and hit 16 of 18 greens on the day. He shot a 7-under 29 on his first nine (the back nine at TPC Scottsdale) before cooling off a bit on the back.
''I finally gave our new RAZR Fit Xtreme a chance,'' Mickelson said after his round. ''And I tell you what, on Tuesday, when I hit it, I kept looking up and I was almost in disbelief at how easy it was, how straight it was, and the misses weren't bad. I put it into play in the pro-am yesterday and I hit it great.
''I drove it phenomenal, and felt really good with it,'' he added. ''And the thing that's so great about it is I can make the same swing with my irons as I do with my driver and the ball goes very straight and easy. … So that was the big thing. I drove the ball much better here.''
Callaway debuted the RAZR Fit Xtreme driver in late November, billing it as the longest fully adjustable driver the company has ever measured, and it is now available at retail. The Xtreme is the second adjustable driver Callaway has developed in the past year or so, following the original RAZR Fit Driver, and company officials say this one advances distance and overall performance over its predecessor.
Speed Frame Face Technology is the headliner of the technological advances in the RAZR Fit Xtreme. It combines Callaway's Variable Face Technology and Hyperbolic Face Technology to enhance the stress distribution across the club's titanium face for more efficient energy transfer from clubhead to ball. It also makes for a larger, more consistent sweet spot and increased ball speed, even on off-center contact.
The Speed Frame Face also saves weight that is then redistributed in the clubhead to improve the Center of Gravity and maximize Moment of Inertia, which leads to improved ball flight, stability and forgiveness. In addition, the face features a tighter bulge radius than the original RAZR Fit Driver for a more preferred look at address, along with more consistent sidespin and dispersion.
The driver's crown features Forged Composite – an advanced carbon fiber material that Callaway has been working with for more than four years. Using this patented, lightweight material, which weighs only 12.1 grams – and gives the RAZR Fit Xtreme the lightest crown in golf – allows Callaway engineers to precisely position saved weight to achieve the lowest Center of Gravity in any fully adjustable driver. This promotes higher ball speed and less spin off the tee for more distance.
Two OptiFit Technology elements make up the RAZR Fit Xtreme's improved adjustability: the OptiFit Hosel and OptiFit Weights. The hosel adjusts the face angle to Open, Square or Closed positions to improve accuracy and trajectory while allowing golfers to dial in their preferred look at address. The 13- and 1-gram OptiFit Weights shift the clubhead's Center of Gravity to promote noticeable Draw or Neutral ball flights. The higher lofts have more draw bias than lower lofts.
And speaking of lofts, the RAZR Fit Xtreme comes in more lofts that incorporate a greater range of face angle options, Center of Gravity bias options and CG height differences than the RAZR Fit Driver. Callaway has optimized the performance in each loft to suit the needs of the players that will use it. For example, they said, the 8.5-, 9.5- and 10.5-degree clubheads are 440cc (versus 460cc for other lofts) and feature a more open face angle.
The RAZR Fit Xtreme features two tour-grade shafts as stock offerings. The primary shaft, the Aldila Trinity, combines Aldila's three patented design technologies (RIP, S-Core, Micro Laminate) into a single shaft design. A secondary offering, the Matrix 7M3 Black Tie, is a heavier, lower launching, lower spinning option for players who generate higher head speed and higher spin.
And for golfers wanting to personalize their clubs, Callaway's udesign option has been expanded for the RAZR Fit Xtreme. Both the crown and the sole of the clubhead are now separately customizable with eight different color choices. And for the first time, custom laser engraving will also be available on the sole.
