"Phil Mickelson will have a new Callaway driver in the bag at the Abu Dhabi HSBC Golf Championship. After spending a good portion of last season employing a driver-less setup — Mickelson used Callaway's taller-faced X Hot 3Deep fairway wood as his "driver" to win the British Open and Aberdeen Asset Management Scottish Open — Mickelson confirmed he would be carrying a 9.5-degree Big Bertha Alpha for the first time.
"As I look back on 2013 I played some of my best golf and had some huge breakthroughs," Mickelson said. "But I did most of it without a driver."
The low-spin Big Bertha Alpha features a "Gravity Core" in the sole of the club that allows spin and launch angle to be adjusted independently (also known as CG height).
"This year, we have the best driver I've ever hit that lowers my spin rate just like my 3‑wood," Mickelson said. "I drive it longer and straighter with my driver than I did with my 3‑wood. It's a whole different weapon in my arsenal now. And if I drive the ball well, like I have been in practice and I have been this off‑season, heading into this 2014 season, could be the best year of my career for that simple reason."
So not only lower spin rates, but notice 9.5 degrees? How many years ago was it most "pro" drivers for in the 6.5-8 degree range. Now man of them are higher than Phil's.
