Getting into the field as the fourth alternate, PGA TOUR rookie Derek Ernst made the most of his eighth start this season by winning the Wells Fargo Championship in a playoff over David Lynn. 

With the victory, Ernst also secured his place in next week's PLAYERS Championship field. 

The 22-year-old recently switched to a PING Scottsdale TR (True Roll) Grayhawk putter at the Zurich Classic of New Orleans and posted his best finish of the season (T47). One week later picked up his first PGA TOUR win with the new putter in the bag.

Every club in Phil Mickelson's bag was working at the Waste Management Phoenix Open, but it was his new Callaway RAZR Fit Xtreme driver that gained the most attention during his four-shot win on Sunday in Scottsdale, Ariz.

Mickelson, who switched from a RAZR Hawk Tour driver to one of Callaway's latest driver offerings on Tuesday, following a productive range session, averaged 298 yards off the tee for the week, including a 358-yard drive during the second round.

“This driver spins so low that I can have more loft on the club, making it easier to hit," Mickelson said. "This has got to be good for every player I would think, but it sure as heck is good for me. And by having it be a low-spin driver with enough loft, and because it's that RAZR Fit Xtreme where you can fit it, I was able to get it dialed in to where it goes straight. But I'm able to make the same golf swing as my irons so you'll see me extend down the target line, you won't see this kind of tilt because it's not enough loft to get up and it's not low enough spin to not float, and it has been — it really could be a revolutionary club for me."

The 9.5-degree driver has an actual loft of 8.1-degrees with 5 grams in the toe and 3 grams in the heel. The 45-inch shaft is a Mitsubishi Rayon Fubuki K. 059 prototype model 70X.

Mickelson also made one other adjustment to his bag prior to the start of the first round, replacing the Callaway X Hot Prototype 3-wood he put in play during the second round of the Farmers Insurance Open with the TaylorMade RocketBallz 3-wood he's been gaming since last November.

Phil Mickelson's bag:

Driver: Callaway RAZR Fit Xtreme Driver (9.5 degrees) with a Mitsubishi Rayon Fubuki K. 059 prototype model 70X shaft
3-wood: TaylorMade RocketBallz (13-degree, bent to 11.5 degrees) with Mitsubishi Rayon Fubuki K 80X prototype shaft
5-wood: Titleist 980F 5-wood (17-degree) with a Graphite Design PM 902 shaft
Irons (4-PW): Callaway RAZR X Muscleback Irons with KBS Tour shafts
Wedges: Callaway JAWS Wedges (52 degrees, 60 degrees, 64 degrees)
Putter: Odyssey Black Series Tour Design #9
Ball: Callaway HEXBlack Tour golf ball

Russell Henley made quite an impression in his first PGA TOUR start. The 23-year-old rookie posted rounds of 63-63-67-63, including a back-nine 29 on Sunday that included five straight birdies, to win the Sony Open in Hawaii by three shots over Tim Clark.

His score of 24-under 256 set the record for the lowest total score at the Sony Open. In the process, Henley became the first player on the PGA TOUR to win with Nike’s new 20XI X golf ball.

Henley used Nike’s 20XI X last season on the Web.com Tour but decided to switch to the latest version, for his first event of 2013 because he felt the new ball, with its larger RZN core, went farther and felt softer around the greens.

Aside from the new ball, Henley also had 14 Nike clubs in the bag for his first PGA TOUR victory.

What Russell Henley had in the bag at the Sony Open in Hawaii:

Driver: Nike VR_S (9.5 degrees) with a Graphite Design HD-7X Shaft
Fairway wood: Nike SQ Sumo (13 degrees)
Hybrid: Nike VR Pro (18 degrees)
Irons: Nike VR Pro Cavity (3-6 iron), Nike VR Pro Combo (7-9 iron)
Wedges: Nike VR Pro (47, 53 and 59 degrees)
Putter: Nike Method 006 Prototype with a long slant neck
Ball: Nike 20XI X

Dustin Johnson’s four-shot win at the season-opening Hyundai Tournament of Champions earned him a return trip to Maui next year for the winners-only event.

But Johnson wasn’t the only winner on Tuesday -- TaylorMade Golf also picked up a big win as Johnson notched his seventh PGA TOUR victory using the company’s R1 driver, which was released on Jan. 3.  

Johnson employed a 10 degree R1 with a neutral face angle and an 8-gram shot shape weight in the toe and 2-gram shot shape weight in the heel for the 54-hole tournament. He averaged 275.9 yards off the tee and recorded a 405-yard drive during the final round, which was the longest in the field during Tuesday’s final round.

He also became the second player to win with TaylorMade’s RocketBladez Tour irons, joining Sergio Garica, who captured the Johor Open in December. 

Even though Johnson spent some time working with the irons during the offseason, he felt his irons were a bit too upright and had the entire set bent 1 degree flatter prior to the first round.

Dustin Johnson’s bag at the Hyundai Tournament of Champions:

DRIVER: TaylorMade R1 (10°) with a Fujikura Fuel 2.0 X shaft
FAIRWAY WOODS: TaylorMade R11S (15.5°) and R9 (19°) with Aldila RIP Series X shafts
IRONS: RocketBladez Tour (3-PW) with True Temper Dynamic Gold X100 shafts
WEDGES: TaylorMade TP xFT (54°, 60°) with with KBS Back Nickel shafts
PUTTER: Scotty Cameron for Titleist Newport prototype
BALL: TaylorMade Penta TP5
