TaylorMade's Ghost Tour Series putter line made its PGA TOUR debut at the Deutsche Bank Championship with two marquee names putting the new flat stick in play.
Sergio Garica switched to a Ghost Tour Maranello 81 and finished T4 for the week and 37th in strokes gained-putting. Garcia had been using an old Ghost Tour MA-81 but preferred the black parallel lines on the trailing edge that reinforced accurate alignment.
Jason Day used a Ghost Tour Monte Carlo 12 for the very first time and finished T13 and 13th in strokes gained-putting. Like Garcia, Day had used putters in the past with a similar head shape to Monte Carlo 12, making the transition to the new putter an easy one.
Phil Mickelson goes with full bag of Mack Daddy 2 wedges: After using a mixed bag of Callaway wedges (X Series Jaws 52, 56 degrees; Forged 60 degrees; Mack Daddy 2 64 degrees) for most of the season, Phil Mickelson put all Callaway Mack Daddy 2 wedges (52, 56, 60 degress) in the bag at TPC Boston and finished the week T58 in scrambling.
Angel Cabrera, Luke Guthrie bag S55 iron: Two-time major winner Angel Cabrera and Luke Guthrie switched to PING's new S55 at the Deutsche Bank Championship. Both players had been playing PING's S56 iron and liked the fact that S55 was more forgiving, and the slightly longer with the long irons.
Guthrie also went with a new shaft in his S55 irons — Project X's 6.5. Guthrie had been playing PX 6.0 since his sophomore year of college but felt the shafts were spinning too much, leading to a loss in distance.
Working with PING Tour rep Matt Rollins, Guthrie switched to the slightly stiffer PX 6.5 and saw an immediate improvement in the flight. He also saw a slight uptick in distance.
Rickie Fowler switches to Odyssey 2-Ball mallet: One week after Rickie Fowler switched from an Odyssey Versa #7 to a Scotty Cameron Notchback prototype at The Barclays, he made another putter switch at the Deutsche Bank Championship, going with an Odyssey White Hot Pro 2-Ball mallet.
Until the switch to Versa #7 earlier this year, Fowler had used a blade-style putter for most of his career. The switch to a new head shape showed in his first event, as Fowler missed the cut and finished near the bottom in strokes gained/putting (-1.865).
Divots: Callaway gave a few staffers a peek at two new prototypes that are currently in the works. The driver features a slidable weight channel that runs along the back of the driver, while the iron has an undercut in the cavity that could lead to increased ball speed. ... Dean Snell, TaylorMade's VP of Golf Ball R&D, did some prototype ball testing with a number of players, including Dustin Johnson, Justin Rose, Justin Leonard, Martin Kaymer, Martin Laird and Rory Sabbatini.
