Indeed, Appleby rode a Odyssey White Hot XG 330 putter to victory. This putter can be found at countless online sporting goods stores for a Benjamin plus tax, despite the fact that it is no longer part of Odyssey’s current White Hot XG offerings.
The White Hot XG 330 putter is a face-balanced mallet with a plumber’s neck hosel with full-shaft offset. It incorporates “Hi-Def” alignment stripes along the flange. A multi-layer insert with a “textured impact zone” is designed to clearly define the sweet spot. Appleby’s putter appears to have a custom double-bend neck instead of the stock hosel (as first noted in the comments section below).
Interestingly, if Appleby had gone with the stock hosel, it would have been the second time in three weeks that a face-balanced putter with a plumber’s or “crank neck” hosel had won a tournament. Louis Oosthuizen won the British Open with a custom Redwood Series PING Anser putter with a custom elongated hosel that makes the putter face balanced.
