Following a stellar final round on Sunday, Mickelson touted his new RAZR Fit Driver, which features Callaway's adjustable hosel and movable weights on the sole, designed to help dial in a player's ball flight.

"I certainly am confident now heading into some of our big events," Mickelson said. "I feel like my putter is back and I feel like I've got a driver that's dialed in with our new RAZR Fit Driver. I've got such control over my flight, trajectory and distance control."

Playing in the tricky weather conditions of beautiful Monterey Peninsula, Mickelson had much praise for his new HEX Black Tour Golf Ball.

"I had a big advantage this week, I felt, because when the winds started coming up, when the rain started coming up, I felt like I had an advantage by the way my ball was flying and controlled through that wind," the four-time major champion told Golf Channel. "We've got a new ball this year, HEX Black (Tour), and it just flew so good and penetrated through the air so much better in this thick, cold air. I felt like I had a big advantage."

In addition to his RAZR Fit Driver and HEX Black Tour Golf Ball, Mickelson's bag featured a full complement of Callaway equipment: a Big Bertha Diablo 3-wood (15 degrees), an X-Hybrid (19 degrees), RAZR X Muscle Back Irons (6-PW), a Callaway Prototype 5-iron and an X-Forged 4-iron. He used his Odyssey White Hot XG PT 82 Blade putter to roll in six birdie putts and an eagle putt. In fact, Mickelson was first in the field in Strokes Gained in Putting over the final two rounds, averaging 3.329 strokes gained. In shooting 70-65-70-64 over the four days on Monterrey Peninsula, Mickelson hit 75 percent of greens in regulation.

The soon-to-be-Hall of Famer's victory marked the second worldwide win with a RAZR Fit Driver, following Alvaro Quiros' convincing win at the Dubai World Championship in December. The RAZR Fit Driver features Callaway's OptiFit adjustability system - designed for easy use and noticeable changes in trajectory for each of the settings. The system allows golfers to adjust the club's face angle to three address positions: Open, Square and Closed. While rotation capabilities in the hosel enables golfers to choose a preferred look at address while also minimizing a slice or hook generated by the club's delivery to the ball. In the driver head, OptiFit weights (one weighing 12 grams and the other 2 grams) are featured in the sole's toe and heal positions. These are movable and can be exchanged to create a meaningful shift in the club's centre of gravity and a perceivable draw or neutral ball flight.

As for their new HEX Black Tour Golf Ball, Callaway claim it boasts several engineering advancements: an innovative Dual-Core construction, an exceptionally durable DuraSpin cover material and Callaway's HEX Aerodynamics. These features and others combine to deliver a five-piece golf ball that has, according to the company, better Spin Separation (the measured differential between the high spin generated on shorter approach shots and the optimal low spin off the driver) than any previous introduction from Callaway.
